PREFACE

There is nothing thrilling in the following pages. They contain the

story of the life-work of a very modest man deeply interested in and

enamoured with the science of chemistry, who sought also to inspire

others and to familiarize the general public of his time with the

intimate connection of chemistry with manufactures and things which

enter so largely into every-day occupations. He was an active member

of a small group of chemists who, in the early years of eighteen

hundred, caused thousands of the laity to give thought to the

possibilities of Chemistry, and in addition was a pioneer in

pyrotechnics, on which account he is deservedly entitled to every

recognition. More than a century has passed since his most serious

efforts were put forth. However, it will not be long until that early

galaxy of chemical enthusiasts of which he was a member will be

accorded a high place in the history of the development of the science

in America.

JAMES CUTBUSH

AN AMERICAN CHEMIST

1788-1823

It is scarcely conceivable that anything pertaining to the development

of chemical science in America would fail to interest its chemists.

The response to the needs of the Nation in the last few years has

shown how marvelously they wrought and the wonderful things which they

brought to light. Yet in the long ago--in the days of which we only

know by hearsay, and through desultory reading, there lived chemists

with enthusiasm, knowledge and initiative, whose aim it was to have

their chosen science contribute to the welfare of humanity. In the

labors of such men as James Woodhouse, Robert Hare, Adam Seybert,

Henry Seybert, John Redman Coxe, Joseph Cloud, Gerard Troost, and many

others, the scientific spirit predominated, although with it went the

purpose, more or less sharply defined, of making their acquirements

useful. Particularly noticeable was this in the instance of Woodhouse.

The general consensus of opinion among present-day chemists is that

chemistry should be helpful to all. It may and should be scientific,

but its principles ought to be scientifically applied in every useful

manner.

The reader, desirous of learning the aims and ambitions of the fathers

of the science in our country, will profit by turning to the files of

the _Aurora_, an old daily paper of Philadelphia, for the year 1808,

and beginning about the middle of July will there encounter a most

interesting series of articles on the applications of chemistry under

the general heading

APPLICATION OF CHEMISTRY TO ARTS AND MANUFACTURES

There are fifteen separate papers. In considering the

period--1808,--the age of the young Republic, and that the times were

far from quiet; that unrest and uncertainty prevailed as to the fate

of the Republic, it does not surprise that thought should have been

given to means of protection; hence gunpowder was the very first

product to engage the author of the series of articles. The proving

and analysis of the powder are discussed at length. The methods appear

very primitive in the light of present-day knowledge, but one must not

forget the period. One hundred years hence the masterpieces of

present-day chemists will perhaps provoke smiles upon the

countenances of those who perchance read them. In this pioneer

contribution on gunpowder analysis the charcoal of the powder is often

called "oxid of carbon." In referring to the separation of potassium

and sodium it is recommended to precipitate out the first in the form

of tartrate. Naturally, nitre itself comes in for serious thought and

the explosibility of the mixture of charcoal, nitre and sulphur

arrests the author's attention, for he emphasizes the fact--

"that, independent of the formation of gases or airs, the

agency of caloric, or matter of heat, generated in the

process of combustion, considerably facilitates the strength

of the powder, in consequence of producing the expansion of

these airs."

Recently, under the pressure of a national necessity, which will not

soon be forgotten, the problem of getting nitre--nitrates and kindred

bodies--had the earnest attention of chemists. So, in the period

before and after 1808, methods of forming nitre had grave

consideration. For instance, this question, now amusing, was

propounded--

"How much nitre could be manufactured from the refuse animal

and vegetable matter of the City of Philadelphia in case of

emergency? What quantity could be prepared by elixating or

washing the rubbish of old buildings, the earth of stables,

cellars, etc., and the soil of certain tracts of the United

States?"

It is quite proper that mention should have also been made of the

natural _nitre beds_, as well as of the artificial beds built up from

slow experience. Reference is made that in France nitre was won from

the lime and rubbish of old, ruinous buildings, and from the floors of

stables and pigeon houses, while it is also recorded that during the

American Revolution, the

"same means, by the hand of economy and industry, afforded

quantities of this article in certain of the then Colonies,

and"

that in the Southern portions it was obtained from the earthen floors

of tobacco houses.

The presentation of the earliest methods of getting nitre is extremely

interesting, extended and elaborate, giving the reader a full view of

pioneer conditions and endeavor. The scheme of purification of nitre

for gunpowder use is illuminating and attractive. Attention is

directed to the saltpetre rock and caves of the western portion of

our country.

The preparation of charcoal is discussed. The adaptability of charcoal

from various sources receives careful thought in connection with its

use in gunpowder; so, too, the sulphur used for this particular

purpose, and there is recommended as a source of this ingredient, the

common pyrites so abundant throughout the States. Among other topics,

of vital interest in these days, discussed in the continuing articles,

is the manufacture of spirit from potatoes. The method employed in

Germany is presented in detail after which it is said--

"Potato spirit of excellent quality has been made in this

city (Philadelphia). It is found, not only to be much cheaper

than grain used entirely, but to afford better flavoured

liquor and other qualities which give it a decided

preference."

Fermentation, yeast and baking receive mention. Brewing and the

different kinds of beer are fully examined. In those days adulteration

was practiced, for wormwood and quassia were found as substitutes. The

preparation of beer and ale for home consumption would very likely

find little favor in the "dry-bone" spirit of the present, much less

would the refining of wines and other spirituous liquors of high

alcohol content meet with approbation. However, such prohibitory

questions as are now discussed did not vitally concern our

forefathers, so that it was most proper and praiseworthy to advise the

public how, through the instrumentality of chemistry, many of the

needed articles of life might be made in the highest degree of

purity. In many homes there existed miniature brewing plants.

At the other extreme, among useful commodities, were the manufacture

of fish glue, common glue, gelatine, albumen, magnesia alba, etc.

The several articles thus published in one of the most respected and

influential papers of that early day--1808--had for their purpose the

education of the general public in the application of a science to

their use, but there was also a desire to arouse a deep and steady

interest in science in general, which seems quite plain from a

quotation from that remarkable address of Dr. John Morgan--at one time

Physician-in-Chief of the American Army. The passage was--

"Oh! let it never be said in this City or in this Province,

so happy in its climate and in its soil, where Commerce has

long flourished and plenty smiled, that science, the amiable

daughter of liberty and sister of opulence, droops her

languid head, or follows behind with a slow, unequal pace."

Doubtless deeply moved himself by this impassioned appeal, the author

of the _Aurora_ papers exclaimed--

"I pronounce with confidence this shall never be the case.

Every useful kind of learning shall here fix a favorite seat

and shine forth in meredian splendour, to accomplish which

may _every_ heart and _every_ hand be united."

And then, probably overpowered by an inner, compelling force and

conscious of the possibilities of his science in the cause of man and

the undeveloped resources of our country, quietly awaiting the

oncoming alterations to be performed by applying chemistry, he

continues with like spirit--

"If ever there was a time to bring the Arts and Manufactures

to perfection in this Country, it is the present; for the

season is approaching, when, of necessity, which is the

mother of invention, our internal resources, and the

application of them to our wants, will advance a brilliant

and glorious epoch in the annals of our Country--second to

none but the declaration of independence. Who is to establish

the _chain_ of manufactures--to convert the crude productions

of Nature into useful articles; but you enlightened citizens,

men of _science_ and _improvement_, _artists_ and

manufacturers. The laboratory of Nature will be thrown open

to you, and to use the scriptural phrase, 'Ye shall know

even as ye are known.'"

Throughout the whole series of these papers there is manifest that

noble patriotic spirit which shows itself in the last paragraph. There

exists also an intelligent and unselfish spirit, so that as one

finishes his reading there comes to mind a query as to the author who

wrote thus in 1808--who was this early advocate of applied

chemistry--this enthusiast in chemistry? Each article bears at its

conclusion the initials _J.C._, which in several of the earlier

articles are erroneously given as I.C. They throw no light on our

curiosity and probably no one would ever have known whom _J.C._

represented had not the man himself in later life confessed that as a

lad of twenty years he penned these papers. They are exceedingly well

composed. They show a wide, general knowledge and also great

familiarity with the science of chemistry. Their young author was

_James Cutbush_.

When Robert Hare was twenty years of age he gave to the world one of

the finest discoveries made by a chemist. Cutbush presented known

chemical facts for the use and improvement of natural conditions.

Might not the young men of these days, surrounded by every sort of

help, make similar earnest and worthwhile contributions? They surely

can do this if they are imbued with the spirit of the forefathers--the

American spirit in chemistry.

Additional evidence of Cutbush's chemical activity at this early age

may be seen in a contribution to the Philadelphia _Medical Museum_

(1808) upon mercury fulminate. This interesting body he declared to be

mercury oxalate and cited as his authority Aikin's Chemical and

Mineralogical Dictionary. He believed that its oxalic acid content was

due to the action of nitric acid upon alcohol. Such being the case, he

argued that he saw no reason why the salt could not be prepared in a

way by which "no alcohol is employed." Accordingly, he mixed

intimately two parts of salt of sorrel and one part of red

precipitate. Upon this mixture he poured sixteen parts of water, and

rubbed the solid mass intimately together. In time the red-colored

mass assumed an ash color, when it was collected on a filter and

dried. In his own words--

"On trying a part of this powder on an anvil with a hammer,

it exploded very violently, the comparison of which to that

prepared by Howard's process was nearly equal."

While Cutbush was in error, relative to the true composition of the

fulminate, he at least gave to the scientific world a characteristic

property of mercuric oxalate, which does explode with considerable

violence, while at 180° C. it quickly breaks down with a mild

explosive effect. Singularly enough, he seems not to have abandoned

the view that the interaction of alcohol and nitric acid give rise to

oxalic acid.

While doing experimental work, Cutbush was active in the dissemination

of science facts through the medium of his pen. Thus it was in this

year (1808) that he published the "Useful Cabinet."

The surroundings of Cutbush were congenial. Woodhouse was at the

zenith of his career. John Redman Coxe figured largely in Philadelphia

science circles. The delightful and widely trained Benjamin Smith

Barton was a prime favorite with the younger men of science; Adam

Seybert was laying the foundations of mineralogical chemistry and

Gerard Troost was soon to appear and give additional zest and impetus

to chemical research. To all these men Cutbush was known and favorably

known, judging from his own allusions to them in his scattered

writings. Of them all he seems to have entertained the strongest

attachment to the celebrated Barton and the talented Coxe, although he

wrote of Dr. Woodhouse as "an experimenter unequalled." It is strange,

however, that his references to Robert Hare are few and meagre. It is

not easy to understand why this should be the case. True, there

existed local prejudices and cliques in the closing decades of the

18th Century and the opening decades of the 19th Century. They are to

be deplored, but humanity is frail and perhaps it is wisest to pass

them by, yet so many things could be better understood if all the

facts were laid bare. Frequent favorable mention was made by Cutbush

of John Redman Coxe, hence probably the appearance of several of his

contributions in the pages of the Philadelphia _Medical Museum_,

edited at this particular time by Coxe. For example, in 1809, Cutbush

published an article on the formation of ether in this journal, and

suggested that the product of the interaction of sulphuric acid and

alcohol could be best purified by distilling it over manganese or lead

dioxide and not over caustic potash as was customary. He also dwelt on

the production of ethylene in this process, attributing its presence

to the dehydrating action of sulphuric acid upon the alcohol.

Momentarily, he rejoiced over this observation, believing it was new,

but promptly subsided when he discovered that Fourcroy and Vauquelin

had long before made the same observations and given the same

explanation. Two years later (1811), in the same journal, Cutbush

reported results gathered from experiments to determine the value of

the hop to brewers. He said much in regard to its essential oil in the

preparation of malt liquor and repeated earlier personal observations

upon the importance of chemistry in the brewing operations--

"An art in which, to the principles of chemistry, many

improvements have been made. To our worthy and ingenious

countryman, Mr. Hare, much praise is due for various

improvements in this art, which, we may add, were in

consequence of his correct principles in chemistry and

natural philosophy."

Here is one of the few references to Robert Hare made by Cutbush. It

was when Hare was devoting most of his time and mental energies to the

development and improvement of his father's business. He applied his

scientific knowledge to it, only in the end to have it fail through

the conditions which came upon the country during the period of the

War of 1812. One cannot easily forget the filial devotion of Robert

Hare to his father in this particular business. Gladly would he have

pursued pure science, but he knew his duty and assumed it, although

unable to devote much time to science until 1818. But that story has

been told. Another appreciation from Cutbush which appears years later

reads as follows:

"The deflagrator of Professor Hare of Philadelphia is an

apparatus well calculated for many interesting experiments

on galvanism. To that gentleman we are indebted for the

compound blowpipe, which produces a very intense heat by the

combustion of hydrogen in contact with oxygen gas.

Notwithstanding Professor Clark of England has laid claim to

the apparatus, and the use of hydrogen gas in this way, the

merit of the discovery is due to our learned and ingenious

countryman."

The next few years in the life of Cutbush were most interesting. He

enjoyed mingling with his fellows, and it is recorded that in 1810 he

became a member of Lodge No. 2, Free and Accepted Masons, comprising

in its membership General Peter Muhlenberg and many other

distinguished Philadelphians in various walks of life. Upon them he

made an exceedingly favorable impression, because in June of 1811,

Cutbush was made presiding officer of his Lodge and frequently

thereafter he was invited to address his brethren upon some of the

topics of the moment. It is quite certain that he also availed himself

in his dignified position to inculcate a knowledge of science, and his

favorite science chemistry in particular, for on the pages of the

_Freemason's Magazine_ for 1811 may be seen "Subjects and Importance

of Chemistry"--an article for laymen in which is plainly set forth how

the science enters every walk of life. In many respects it recalls the

introductory chapter of Parke's Chemical Catechism, for it advises how

chemistry

"removes the veil from the fabric of Nature, and makes us

acquainted with all the phenomena which happen around us."

The offerings of Cutbush were fitting and most timely. They aroused

the interest of his audience and induced many to enter upon scientific

pursuits. At one place he enlarged upon the wonderful medicinal

properties of a chalybeate water near Colestown, N. J., giving its

analysis and the healthful effect it seemed to produce on those who

used it.

Again, in the December issue of the _Freemason's Magazine_ (1881), he

presented a most interesting, readable and succinct historical sketch

of our science which concludes as follows:

"Thus chemistry is become an entirely new science. It is no

longer confined to the laboratory of the arts: it has

extended its flights to the sublimest heights of philosophy,

and pursues paths formerly regarded as impenetrable

mysteries. Placed forever in the elevated rank it now holds,

rich with all its new conquests, it is become the science

most adapted to the sublime speculations of philosophy, the

most useful in advancing all the operations of the arts, and

the most rational for scientific amusement. Exact in its

process, sure in its results, varied in its operations,

without limits in its applications and its views, severe and

geometrical in its reasoning, there is scarcely any human

occupation which it does not enlighten, and upon the

perfection of which it may not have great influence. It

bestows great enjoyment to every class of individuals: and

who would not be ambitious of becoming acquainted with a

science which enlightens almost every species of human

knowledge?"

Imagine for a moment the effect of such an enthusiastic proclamation

of the powers of chemistry on the readers of the Magazine! It would

be and no doubt was contagious, with the consequence that our science

was called upon to aid infant industries. Cutbush was far-visioned and

dreamed of the development of our Country's national resources. He had

the spirit of Woodhouse, Seybert and others, who, too, were actuated

for our Country's welfare, for its development physically and

spiritually, and how better could this be accomplished than through

the medium of science, and in large measure by chemical science?

In his historical resume Cutbush mentions some

"of the philosophers who have ... cultivated and enriched the

new theory of chemistry with discoveries which will forever

give immortality to their names, we have to notice Aikin,

Babington, Bancroft, Beddoes, Blagdon, Cavendish, Chenevix,

Crichton, Cruickshank, Davy, Lord Dundonald, Lord Dundas,

Fordyce, Garnett, Hatchett, Henry, Higgins, Hope, Howard,

Kirvan, Bishop of Llandaff, Murray, Nicholson, Pearson,

Tennant, Tilloch, Thompson, Wedgwood, and Wollaston; and

Achard, Crell, Gilbert, Gren, Goetling, Humboldt, Hermbstadt,

Klaproth, Lowitz, Richter, Scherer, Tromsdorff, Westrumb,

Wiegleb, Bertholet, Chaptal, Fourcroy, Lagrange, Guiton, Van

Mons, Proust, Sequin, Vauquelin, etc., etc."

To the modern chemist these names probably represent little. Perhaps a

few sound familiar, but the majority are unknown to him. For instance,

who would be apt to say much about the Bishop of Llandaff, who wrote

to Henry, author of one of the earliest and most delightful texts:

"CAMBRIDGE, Oct. 28, 1787."

"Sir--

"Allow me to return you my thanks of the obliging manner in

which you conveyed to me the kind notice, which the Literary

and Philosophical Society were pleased to take of my essay;

and to assure you at the same time that it will give me great

pleasure to be acquainted with a gentleman who is so

eminently distinguished for his skill in chemistry, as you

have shewn yourself to be. I have been told by good

authority, of an odd fact relative to calcined mercury, the

fact is this: A bottle which contained some calcined mercury

which had been purchased in London was left standing without

its cork for near thirty years without being looked at. When

it was examined, the greater part of it was revivified.

"I have the honour to be, Sir,

"Yr obliged servt

"BP. LLANDAFF."

And this celebrated Bishop was no less a personage than Dr. Watson,

whose "Chemical Essays" are most charming, instructive reading at the

present moment. Students of the history of our science will find them

to be so.

But all these early chemists--ancient, if you please--are gone. They

cultivated chemistry with pleasure and ardor. Some left visible

imprints, while scarce a vestige remains of others. Their labours have

made our path easier. A century hence, many honoured to-day and

respected for their achievements, will receive scant consideration,

though the work of the present looms up large in our judgment.

The founding of the Columbian Chemical Society in 1811 was an event in

the chemical circles of Philadelphia. The old Chemical Society of

Philadelphia went out of existence in 1809, with the death of

Woodhouse. The new organization was founded "by a number of persons

desirous of cultivating chemical science." It comprised many young men

zealous in research. The names of eminent foreigners and distinguished

Americans are upon its rolls. Its meetings were monthly. Each year, at

the fall opening, "an oration on some chemical subject" was delivered.

Every month some member was appointed to read "an original chemical

essay." It was recorded that

"any person desirous of membership ... previous to his

election ... shall read an original essay on some chemical

subject on which any member may speak not more than ten

minutes."

This feature was held to be important; at least the daily papers made

note of it, as is evident from the subjoined excerpt:

"The following gentlemen have been elected Junior members of

the Columbian Chemical Society, during the last year, after

having read original dissertations, the subjects of which are

attached to their respective names:

"Mr. T. W. Robertson, 'Objections to the Existence of a

Principle of Repulsion.'

"Mr. Francis Brognard, 'On Chemical Affinity.'

"Mr. Lewis Gerhardt, 'On Light.'

"Mr. Dudley Burwell, 'On the Chemical Properties and Medical

Uses of Arsenic.'

"Mr. Jeremiah J. Foster, 'On the History, Nature and

Properties of Oxygen Gas.'

"Mr. J. C. Foster, 'Objections to the Antiphlogistic Theory

of Combustion.'

"Mr. Charles Gignilliat, 'On Hydrogen Gas.'

"Mr. John Bent, 'On Oxygen Gas.'"

The monthly meetings were announced in the city papers. The

announcements appeared at intervals through a period of years, hence

it may be assumed the Society was an active organization and that its

members regarded it as of consequence. The personnel of its official

family is not devoid of interest at present. A single volume of

memoirs, printed in 1813, is still extant and may occasionally be

seen; from it will be learned that the "Hon. Thomas Jefferson, Esq.,

was the Patron" of the Society and its President was "James Cutbush,

Esq., Professor of Natural Philosophy, Chemistry and Mineralogy in St.

John's College."

Turning to the table of contents two contributions from the President

are observed. The first relates to the "Prognostic Signs of the

Weather" and the second is "On the Oxyacetite of Iron as a Test or

Reagent for the Discovery of Arsenic." There is little chemistry in

the first contribution, and the second possesses value chiefly in the

qualitative way. They were evidently dashed off with the idea of

arousing discussion, in the hope that serious efforts might be set in

operation in certain directions.

The thought which intrudes itself in looking through the _Memoirs_,

noting the character of the individuals in the membership, and upon

recalling the chemical activities of Cutbush, is as to the man

himself. Why should he, barely twenty-three years of age, be chosen to

such an important and prominent station as that of President of the

Columbian Chemical Society? What manner of man was he? What his

qualifications, his fitness and his position in the science world of

Philadelphia? A search through ancient volumes in many libraries

failed to bring to light any facts bearing on these points. The only

fact discovered that had any value came from a newspaper advertisement

bearing the date October, 1819. It read:

"_Bleaching Liquor_, _Artificial Musk_, _Phosphate of Mercury

and other chemical Preparations_, prepared and sold by

"JAMES CUTBUSH

"Chemist and Apothecary

"No. 25 South Fourth Street, Phila.

"where complete collections of chemical reagents are kept as

usual."

Here is a hint as to the occupation of Cutbush. He was a

chemist--presumably a manufacturing chemist, supplying the necessary

reagents to persons desiring them for their chemical studies; and

further he was a pharmacist serving the various requirements of the

medical men of the City.

Thorough search through newspaper files disclosed that from the year

1811 and perhaps two years earlier, and extending up to the year

1813--various announcements were made by Cutbush as to lectures of a

public nature. These help us realize the character of the individual

and his work. For example--

"Dr. Cutbush's course of _Evening Lectures on Chemistry_ will

commence early in the second week in November, at the

Laboratory in Videl's Court, in Second, near the Corner of

Chestnut St."

and several months later the following notice was found--

"_LECTURES_

on

_THEORETICAL AND PRACTICAL PHARMACY_

"The subscriber, at the solicitation of several medical

gentlemen, proposes to give a series of Lectures on the

Theory and Practice of Pharmacy, accompanied with the

necessary chemical elucidations.

"Tickets may be had at 25 South Fourth St.

"Price 20 dollars.

"JAMES CUTBUSH."

This was in the year 1812. Early in 1813, a year after the preceding

announcement, there appeared--

"J. Cutbush has the pleasure to announce to the ladies and

gentlemen composing his class that the lectures on Chemistry,

as well as those which are to follow on Mineralogy and

Natural Philosophy, will be given in St. John's Lyceum in a

building lately erected at the Corner of Chester and Race,

between Eighth and Ninth Sts.

"N.B. The next lecture will be delivered this evening

(Saturday) when, at the request of several ladies, the

nitrous oxide or the exhilarating gas will be exhibited."

These announcements exhibit a phase in the development of chemical

science which is worthy of pause and reflection. Science subjects had

taken hold of many persons in the early years of the Nineteenth

Century. Some of them became ardent enthusiasts and missioners in the

extension of those subjects. As early as 1808 M. Godon gave lectures

on Mineralogy, and in 1810 announced a work of two volumes with a

quarto supplement of charts. The science of chemistry also had its

advocates. Cutbush was evidently one of them, although not the first.

This honor belongs to Dr. Patrick Kerr Rogers, father of William B.

Rogers, founder and first president of Massachusetts Institute of

Technology and President of the National Academy of Science, of Dr.

Henry D. Rogers, the eminent geologist, and of James B. and Robert

E.--both distinguished in the chemical field.

It was in 1802 that Patrick K. Rogers received his medical degree and

embarked upon practice. Having spare time, he began public lectures on

the sciences, confining himself from 1807 to chemistry. He was very

successful. One of his advertisements as it appeared in the _Aurora_,

in 1809, read:

"EVENING LECTURES

MEDICAL AND CHEMICAL

For Gentlemen

DR. P. K. ROGERS

"Having commenced a course of experimental lectures on

Chemistry to ladies, proposes to give a similar course to

gentlemen at a different hour. Twelve o'clock is the hour

fixed for the former, but as the gentlemen of the city are

variously engaged in business during the day, an evening hour

will be more convenient for them. The evening course is

particularly intended to accommodate men who have a taste for

scientific information and who cannot, on account of their

respective engagements during the day, attend the lectures

in the University.

"A course for gentlemen will commence on Tuesday and will

terminate in the last week of February. The hour will be

seven o'clock in the evening. Two lectures at least,

sometimes three, will be delivered every week. About 1500

interesting experiments will be exhibited and submitted to

the familiar inspection of the class. Several important

experiments not hitherto introduced in any series of chemical

demonstrations in this place will be displayed in the

illustrations of different subjects.

"The laboratory is in the lecturer's house in South Ninth

Street, opposite the University and is furnished with an

excellent chemical apparatus.

"The tickets for this course will be ten dollars. The persons

to take tickets will be entitled to the use of the

lecturer's excellent medical and chemical library during the

season.

"Persons wishing to attend this course will please call at

the lecturer's home at any time before next Tuesday in order

to enter the names on the list.

"Ladies are informed that the list of subscribers to their

course will not be closed until next Monday at twelve o'clock

at the hour the next lecture, properly the first of the

regular series, will be delivered. Gentlemen are not admitted

to these lectures."

In 1810 Dr. Rogers gave out a Syllabus of 12 octavo pages "On

Experimental Lectures on Natural Philosophy and Chemistry," in which

great emphasis was laid on the practical application of these

sciences. It also stated that "it is even esteemed, in some measure,

a cause of shame, for persons of respectable education, to be

ignorant of their general principles." In one newspaper announcement

Rogers said that in order to get sufficient space for his audience he

had procured the "use of the elegant and spacious ball room of M.

Guillou." In this special work he was repeating the labors of Sir

Humphrey Davy in London. In reality, Rogers and his contemporaries and

coadjutors were pioneer University Extension Lecturers. They sought to

popularize the natural and physical sciences and also broaden the

vision or outlook of their hearers. In the case of Cutbush there was a

strong desire to utilize chemistry in manufacture. This he emphasized

more strongly than any other lecturer.

Another participant in the science propaganda was Dr. Thomas P. Jones,

who devoted himself to Chemistry. The following notice of his lecture

course is not devoid of interest:

"On Saturday, the 13th inst., at seven o'clock in the

evening, at Dr. Jones' Chemical Lecture Room, S.W. Corner of

Fourth and Chestnut Streets, a lecture will be delivered on

the properties of nitrous oxide, or the exhilarating gas,

accompanied with a number of experiments. A large quantity

will be prepared to exhibit its effects when inhaled.

"Tickets at fifty cents each may be had at A. Finley's

Bookstore, S.E. Cor. of Chestnut and Fourth Streets, or at

the lecture room on the stated evening."

On perusing early chemical texts and advertisements, such as those

just given, attention is pointedly called to nitrous oxide, especially

to its exhilarating properties, for then it was "_laughing gas_!" One

Philip H. Nicklin published a brochure entitled

"THE ONLY GENTEEL WAY OF GETTING DRUNK

"A character representation of the effects produced by

inhaling nitrous oxide gas. The accuracy of which no man

breathing can deny. Price 25 cts."

To-day, nitrous oxide means a benign anæsthetic, so helpful and

merciful when one is brought under the knife of the skillful surgeon.

The honor accorded Cutbush by his election to the Presidency of the

Columbian Chemical Society was merited. He was not only an active,

intelligent chemist, devoted to the advancement of his science in all

directions, but he seems to have been an ardent enthusiast in the

cause of education, for on the 7th of November, 1811, he delivered an

Oration on Education before the Society for the Promotion of a

Rational System of Education. His audience was large and consisted of

the very best people of the city. The printed oration shows that in

addition to his chemical knowledge he was versed in the humanities, in

mathematics, in philosophy and ancient history. To-day the intelligent

reader would pronounce the oration scholarly in every particular. His

chief purpose seems to have been to introduce into what was then the

customary curriculum in schools a definite amount of science--natural

and physical. This is marked in the title of the organization before

which he appeared on the occasion referred to, in Old St. John's

Church. The whole community was interested in education. A society of

educators had existed for a number of years. Neef had for a long time

been advocating a system which was in reality a modification of the

Pestallozian System, and men in every walk of life were seriously

considering the innovations and advancements in this all-important

subject.

Little can be found in regard to the Society for the Promotion of a

Rational System of Education, but it may be inferred that the society

had branches throughout the city and perhaps far beyond, because

elsewhere Cutbush spoke of the society as under the Presidency of John

Goodman, Esq., and that its purpose was to bring about a reformation

in education. Further, Goodman was a prominent layman in the Church of

Old St. John, who with his associates, Messrs. Greiner and Braeutigam,

fellow churchmen, deeply impressed with the new thought, seem to have

established a school "formed out of the Lutheran congregation of the

Church of St. John ... instituted several professorships ... one of

which, that of Chemistry, Mineralogy and Natural Philosophy" was

conferred upon Cutbush, who proceeded to deliver courses on these

subjects.

Desirous of learning something in regard to St. John's College, the

authorities of St. John's Lutheran Church were consulted. It must be

remembered that this is the oldest English-speaking Lutheran Church in

America. It was founded by General Peter Gabriel Muhlenberg, and a

unique distinction of this church is that in a period of 113 years it

has had but three pastors. Nothing in the minutes of the church showed

that a movement toward the establishment of a college had ever been

made. Moreover, search in the archives of the State Department failed

to bring to light the granting of a charter for an institution bearing

the name of St. John's College, although in an old directory of

Philadelphia, reference is made to St. John's College, and to the fact

that Cutbush was Professor of Chemistry, Mineralogy and Natural

Philosophy in it. The same source of information declared that "the

lectures were held back of St. John's Church in Race Street." It may

be questioned whether Messrs. Goodman, Greiner and Braeutigam, who

were the leaders of the congregation in the early years of 1800, and

enthusiasts in regard to the reformation in education, did not,

perhaps, carry out their thought without consulting the rest of their

church associates. In the history of the church there is a singular

reference to the purchase of houses and lots which were known as "the

fourteen chimneys" and the statement is made that the object of the

purchase is not given. These "fourteen chimneys" may have been the

buildings back of St. John's Church on Race Street.

Benjamin Smith Barton was another professor in St. John's College, who

devoted himself to Natural History and Botany. Mr. Greiner, who was

associated with Messrs. Goodman and Braeutigam also taught in the

institution, and the head of the college or school was a Mr. Bachman,

who later became a Lutheran clergyman and naturalist of high repute in

South Carolina.

It is interesting at this far-away day to note the purposes of the

Society for the promotion of education as set forth in its

constitution. Among other things, it is said "the education of youth

in useful knowledge ought to be a primary object with parents and

friends, that more especially ought every endeavour to be made in a

religious community to lay a sure and solid foundation for every moral

and social virtue. Impressed with a conviction of this important

truth, a number of the members of St. John's congregation, willing to

give every aid within their power toward the establishment and support

of a Rational System of Education, have formed themselves into a

Society for that purpose."

The copy of Oration on Education, printed by Cutbush, which it was the

privilege of the writer to peruse, was the copy handed by Cutbush "To

Dr. Seybert with the compliments of the author." In spite of age,

these words are very clear and legible, and if the only relic by which

to judge of the character of Cutbush, would indicate him to be a man

of intelligence.

There were many other societies extant at this period and through

subsequent years which had for their object the promotion of

scientific education. Among these was the Linnean Society, of which

James Cutbush was Vice-President.

Cutbush had the honor of being one of the few of the original Society

of Philadelphia for the Promotion of National Industry, whose essays

excited the attention of the citizens of the United States. Samuel

Jackson, M.D., Professor in the College of Apothecaries, was one of

the most active members.

Amidst all the activities of Cutbush as a manufacturing chemist, as a

teacher of the science, as a promoter of educational reforms, as a

member of many organizations, he was very busy in a literary

direction. For example, in 1812 he published a brochure on

Hydrostatics, in which were described various hydrometers and their

application. Numerous tables appear in it as well as many interesting

and serviceable problems. It was designed for and was helpful to

artisans and to beginners in the science of physics and chemistry. It

is appropriately dedicated to the Columbian Chemical Society.

In the year 1813, Cutbush placed before the public his "Philosophy of

Experimental Chemistry" in two volumes. It was dedicated to the

"Professors and Students of the University of Pennsylvania and to the

Trustees of St. John's College." One cannot fail to wonder why Cutbush

should have so honoured the University when there is no record

anywhere that he ever pursued studies under the ægis of the

University. Indeed, it will probably remain a query as to where he

was educated. He is often spoken of as "Doctor Cutbush" and in at

least two instances the title "M.D." is placed after his name, yet it

is a fact that in no place where he personally was responsible for the

printing of his name is there any title affixed to it. Every source of

information from which it was hoped to ascertain where Cutbush might

have obtained the Doctorate in the first decade of the 19th Century

failed to produce the fact. Libraries were searched and volumes that

ordinarily convey such information were studied without positive

result.

The little contribution on the "Philosophy of Chemistry" was favorably

known, for Silliman, in his reference to Gorham's Chemistry as the

first book upon this subject by a native American, credits Cutbush

with having written a similar work, but speaks of the effort of

Cutbush as more elementary and not as exhaustive as that of Gorham.

The introduction in the first volume of Cutbush's work will always be

interesting to American students of the science. For example, this

quotation:

"Several original works have, accordingly, appeared, and some

editions of European treatises have been published with

revisions, corrections and additions by our countrymen. The

Chemical and Economical Essays of Pennington, the edition of

Chaptal enlarged by the late James Woodhouse ... that of

Henry's Chemistry by Professor Silliman of Yale College, with

some others, evince not only the learning and talents of our

countrymen, but a growing taste for the encouragement of

learning and the acquisition of chemical knowledge. Besides

these, in the Transactions of our Societies and in the

journals, or periodical works, several valuable papers have

appeared. The genius of the medical students of the

University of Pennsylvania, in particular, has been shown in

a number of excellent inaugural dissertations, some of which

have added to the improvement of chemical science.

"The first teacher of chemistry was Dr. Benjamin Rush ... who

may justly be styled the father of chemistry in America. He

commenced a course of lectures on this science in the then

College of Philadelphia; and although chemistry at that day

(1768) may be said to have been in its infancy, yet the

Doctor did honour to the chair, the school, and his country.

We now speak of him only as a chemist.... The advancement of

chemistry in our city ... is also indebted to other

institutions. The American Philosophical Society, the College

of Physicians, instituted in 1787, the Medical Society,

formed in 1771; the Chemical Society under the patronage of

Doctors Woodhouse and Seybert, which has since been

dissolved; the Linnean Society, instituted under the

presidency of the learned Dr. Benjamin Smith Barton; the

Columbian Chemical Society, founded in 1811; the Academy of

Natural Science--all show the zeal for useful knowledge and

philosophical inquiry.... For the introduction of popular

chemistry, the citizens of Philadelphia are also indebted to

Doctors Rogers and Jones, and to Benjamin Tucker, who have

taught Chemistry with much zeal and talents."

Many attractions are found in the Philosophy of Experimental

Chemistry. The first discussion is that on Chemical Affinity. Two

experiments are introduced. In the first it is stated

"If equal parts, by weight, of sulphur and mercury be

introduced into a crucible, and in this situation exposed to

a sufficient heat; a compound will be formed, called

sulphuret of mercury."

In the second experiment the student is advised to

"Mix together sulphur and potash, and throw them into water;

the sulphur will separate. If the same articles be put into a

crucible and melted, and then thrown into water, the sulphur

as well as the potash will be dissolved."

And next comes the

"_Rationale._ In the first experiment there is an instance of

chemical action, as well as of single affinity, for the

sulphur and mercury would remain separate if heat was not

applied. In consequence of this agent, they unite into an

uniform whole, totally inseparable by mechanical means, and

possessing characters distinct from either of its constituent

parts.

"In the second experiment, the union of sulphur with potash

is effected by heat; for if a sulphuret was not formed, no

solution of the sulphur would take place. Hence it is that

chemical action is the consequence of a power, without which

it could never ensue, and with which it always acts in

unison. This power is affinity."

Then it is remarked:

"Chemistry is a science, which has for its object to discover

the constituent properties of bodies, the result of the

various combinations, and the laws by which those

combinations are effected. Its operations being either

analytical or synthetical, consist of composition, or

decomposition. The laws which govern chemical changes have

been resolved into those of attraction or affinity. Affinity

of composition of chemical affinity differs from that of

aggregation or cohesion or corpuscular attraction, by acting

upon matter of a different kind; or by taking place between

the ultimate constituent parts of bodies, producing by its

action, substances possessing properties frequently very

different, and sometimes contrary to those of the constituent

parts."

Throughout the book the order of presentation is the experiment,

rationale, and remarks. A study of the "Philosophy" shows clearly

that Cutbush presented his material in a rather original fashion. His

method is not observable in any of the text-books of that date.

In discussing potash, Cutbush wrote:

"It has been supposed ever since our countryman, Dr.

Woodhouse, made an experiment with potash that this alkali

had an inflammable base. I am disposed to believe that the

Doctor was the first one who hazarded this conjecture as to

the inflammable nature of potash _when treated in certain

ways_. The Doctor found that a mixture of pearl ash with

soot, calcined by a very intense heat in a covered crucible,

when cold caught fire on the affusion of water. The

experiment was repeated with charcoal with the same result

and the inflammation probably arose from the action of the

base of the alkali on the water."

He says:

"That Thomas Cooper ... repeated this experiment, and

succeeded, I think, after several attempts, in procuring the

metal. Dr. John Redman Coxe and myself also performed it, but

in our attempt we failed. The professor, however, persevered,

and finally procured it.... My brother, Dr. Edward Cutbush,

succeeded in procuring it by using the heat of a

black-smith's forge. I have not heard of any other attempts

in this country except by a gentleman in New York, who was

also successful."

These statements substantiate the idea that Woodhouse isolated the

metal potassium quite independently from any European chemist; it even

looks as if he may have isolated it in the manner referred to before

Sir Humphrey Davy had separated it with the aid of the electric

current.

In the first volume of the Philosophy there is a frontispiece, a lamp

furnace, consisting of a brass rod, fastened to a piece of metal,

furnished with rings of different diameters, and thumb screws to raise

or lower the lamp and rings when in use. By this furnace evaporation,

digestion, solution, sublimation, distillation and other processes,

which require a low temperature, may be performed.

And in the second volume there is a frontispiece representing a

portable universal furnace, made of strong wrought iron plates and

lined with bricks bedded in fire-proof loam. The height of the furnace

is two feet. The body of the furnace is elliptical. There are three

openings in front of the furnace, one above the other, furnished with

sliding doors, and fitted with stoppers made of crucible ware.

Both pieces of apparatus represent a marked advancement. They were

evidently exceedingly useful. By their means it was possible to

execute excellent work.
