When the microscope was first invented, it was regarded as a mere

accessory, a plaything, an unnecessary addition, and an imposition

upon the medical profession and upon the public in general. But since

1840, when the European oculists and scientists began to make

microscopical researches and investigations, not only in the medical

profession, but also in botanical and geological studies, etc., and

since 1870, when, throughout the civilized world, the microscope came

into general use in chemical analysis and other studies, it ceased to

be considered an accessory, and is now regarded as an extremely

necessary apparatus, especially in minute examinations and

investigations; also in the advancement of every branch of science and

art.

Had Galen, Celsus, Hippocrates, and the other great scientists of old,

known the use of the microscope, they would have made no such grave

blunders as in the advocation of the theory that the arteries of the

human body contain and carry air during life, instead of oxygenized

blood only. They were of the erroneous opinion that the blood stayed

in the extremities, not to nourish and sustain the tissues, but simply

to act as a humor in lubricating the same (tissues).

Then, again, had it not been for the microscope, the great English

surgeon and physician, James Paget, would not have discovered that

deadly parasite, the trichina-spiralis, which had already slaughtered

thousands upon thousands of human beings. And yet the existence of

trichina-spiralis may be dated as far back as the time of Moses, who

even then advocated prohibition of the use of pork as a food, and who

considered pork not only an unwholesome food, but dangerous and even

poisonous.

The microscope is certainly the best friend that a scientist can have.

A physician without a microscope is like a man without eyes: he is

uncertain and unprotected and must be considered incompetent, simply

because he cannot arrive at a correct and positive conclusion in

diagnosing and prognosing his case.

The value of the microscope cannot be overestimated, at least in the

examination of the sputa of a human being, and thus being able to

state positively whether or not the man is suffering from consumption

(Tuberculosis). How important it is to be able to state with certainty

at an early date whether or not the patient is suffering from cancer

of the stomach, by examining the vomits microscopically.

The microscope is composed of a simply constructed horse-shoe or

tripod base with a column, tube, reflector, and lenses of different

magnifying powers, ranging from one to five thousand diameters. It is

a most extraordinary and at the same time a most simple apparatus, an

invaluable instrument, whose use any person with a little skill can

learn in a few hours' practice.

Much has already been published of late years concerning the

microscope applied in a medico-legal sense (examinations). This surely

is a very broad field and much remains for future observation and

investigation. Everything that concerns medical examinations in a

legal sense or legal examinations in a medical sense can be

facilitated and accurately determined by the use of the microscope.

For instance, let me call your attention to the world-renowned

"Cronin" case of Chicago, in which the medical experts demonstrated to

a certainty that the blood, hair, and brain matter found in the

Coulson cottage and sewer drop were those of a human being. And what

was still more remarkable they demonstrated by the microscope

accurately and positively that the hair and blood found in the cottage

and fatal trunk were those of the late Dr. Cronin, only in a modified

condition.

Without a doubt the microscope is the most advantageous and most

efficacious apparatus that a scientist has ever invented and

constructed. It is an especially powerful factor in enlightening

complex and difficult cases concerning medico-legal examinations,

where the combined efforts of an attorney and an expert microscopist

are required. Within the last decade, scientists have demonstrated to

a certainty the possibility of distinguishing old and dried human

blood spots, whether on clothing, wood, iron, or any other object,

from those of animal blood. Scientists, especially pathologists and

histologists, have demonstrated the great value of the microscope in

distinguishing not only the skin, blood, hair, and brain matter, but

also the excretions and secretions of the human body from those of

animals.

Again, the microscope applied in medico-legal practice, particularly

in malpractice suits, suits for damages, those requiring the detection

of adulteration of food or drink, is of the greatest importance. It is

not less valuable in determining the purity of an article, especially

whether or not the food or drink has spoiled or undergone

fermentation, and in detecting the accumulation and development of

microorganisms such as germs, bacilli, etc. Prominent among these uses

are of course the detection of oleomargarine, the adulteration of

drugs, liquors, milk, groceries, sausages, etc.

The utilization of the microscope as a factor in the solution of legal

difficulties is as interesting as it is valuable, and in that

connection I wish to cite a few lines from an exhaustive paper read by

the Hon. Geo. E. Fell, M. D., F. R. M. S., before the American Society

of Microscopists, relating to the "_Examination of Legal Documents

with the Microscope_."

"This subject is of practical importance, in which the value of the

microscope has again and again been demonstrated. On several occasions

have we been enabled to clear the path for justice to ferret out the

work of the contract falsifier, and shield the innocent from the

unjust accusations of interested rogues. The range of observations in

investigations of written documents with the microscope is a broad

one. We may begin with the characteristics of the paper upon which the

writing is made, which may enable us to ascertain many facts of

importance; for instance, a great similarity might indicate, with

associated facts, that the documents were prepared at about the same

time. A marked dissimilarity might also have an important bearing upon

the case. The difference of the paper may exist in the character of

the fibres composing it, the finish of the paper whether rough or

smooth, the thickness, modifying the transmissibility of light, the

color, all of which may be ascertained with the microscope.

"The ink used in the writing may then be examined. If additions have

been made to the document within a reasonable time of its making,

microscopic examination will in all probability demonstrate the

difference by keeping the following facts in view: Some inks in drying

assume a dull, or shining surface; if in sufficient quantity, the

surface may become cracked, presenting, when magnified, an appearance

quite similar, but of a different color, to that of the dried bottom

of a clayey pond after the sun has baked it for a few days. The manner

in which the ink is distributed upon the paper, whether it forms an

even border, or spreads out to some extent, is a factor which may be

also noted. The color of the ink by transmitted or reflected

illumination is also a very important factor. This in one case which I

had in hand proved of great importance and demonstrated the addition

of certain words which completely annulled the value of the document

in a case involving several thousand dollars. And in a certain case

where the lines of a certain document were written over with the idea

of entirely covering the first written words, the different colors of

the inks could not be concealed from the magnified image as seen under

reasonably low powers of the microscope."

The value of the microscope in this field of research is so great and

the facts elicited by it so vital, I wish to emphasize its practical

utility as strongly as possible. Of course the principal object in

such an examination of written or printed documents is the erasures or

additions; then the coloring of different inks applied and the mode of

their execution. As to erasures, this can be accomplished in two ways,

either by the use of a penknife or by a chemical preparation. The

former is the one most commonly resorted to, and is effected in the

following manner. With a well sharpened knife blade the surface of the

paper is carefully scraped until all objectionable lettering and

wording appear to the naked eye to have been effaced; but under a

microscopical examination the impression made by the strokes of the

pen may easily be detected, while the different colors of the inks are

still plainly visible under the microscope.

The second method is by the application of a chemical preparation by

which the ink is made soluble and is then easily removed from the

paper by means of a blotter or absorbent cotton. Of course this method

is also an imperfect one and the letters can easily be traced by close

observation. When a chemical preparation has been used for erasing

purposes, I find that in most cases it leaves a stain and also that

the fibres of the paper are more or less destroyed by the chemical

used; thus always leaving evidence that the document has been tampered

with.

George E. Fell in his excellent paper says: "The eye of the individual

making the erasures is certainly not sufficient, and even with the aid

of a hand magnifier, the object might not be effectually accomplished.

We will find that the detection of an erasure made by the knife is a

very simple matter and may be detected by the novice. An investigation

may be made by simply holding the document before a strong light and

this is usually all that is necessary to demonstrate the existence of

an erasure of any consequence.

"This is, however, a very different matter from making out the

outlines of a word or detecting the general arrangement of the fibres

of the paper, so as to be able to state whether writing has been

executed on certain parts of the document; and again, when we enter

into the minutiae of the subject, we will find that the compound

microscope will give us results not to be obtained by the simple hand

magnifier."

On several occasions I have had the opportunity for demonstrating with

the microscope additions made to certain documents, two of which were

wills (testaments); these additions were made in the following

manner:--First an erasure was made and then the additional matter

written over the erasure. With the microscope I could at once detect

the erasure beneath the addition; also the different colors of the

inks. Then, and this is the most important result of the microscopical

examination, by close observation, I could discern the strokes of the

pen in the original lettering as well as those of the additional

lettering, and finally the general mode of their execution.

In regard to the examination of legal documents, United States

currency, printed and written matter, mutilated documents, including

forgeries, etc., from a legal point of view (as to their genuineness),

it will suffice to say that the principal features are, as already

stated, first, the detection of erasures and additions; second, the

comparison of the colors of the different inks used in the original

and in the additional lettering, and finally the mode of their

execution. This includes of course a careful observation of the

original writing as to the general and comparative expression. In the

observation of the characteristics of the letters constituting the

document, I will call attention especially to the shading and general

formation of the letters, that is, the stroke of the pen either in a

downward or upward movement. This comparison includes both capital and

small letters and even punctuation.

All these things, as well as the grammatical and orthographical

relationship and comparative differentiations, must be taken into

consideration in order to enable the microscopical examiner to give a

positive opinion.

A microscopical examination of paper documents, such as wills, notes,

checks, etc., as to whether or not they have been mutilated or forged,

is certainly the most reliable test, and by far the easiest and

simplest method of determining the authenticity or spuriousness of a

document. An expert microscopist and observer can at once arrive at a

correct and positive conclusion as to the genuineness of an autograph.

The use of the microscope in the examination of United States currency

is invaluable, and I believe the only perfectly reliable test for

distinguishing counterfeit currency from the genuine bills. In this

examination the following observations are necessary, to the last of

which I wish to call special attention: First, the quality of the

paper used; second, the general execution and finish of the bill;

third, the ink used for the printed reading matter as well as for the

autograph; fourth, the two red lines; these lines in a genuine bill

are produced by two red silk threads woven into the paper, and running

lengthwise of the bill. In a counterfeit bill these lines are not of

silk thread, but are simply two lines drawn with red ink. This is the

crowning test in the detection of counterfeit currency, and I have no

doubt that the same tests will hold good in the examination of foreign

currency.

A GRAIN OF GOLD.

BY WILL ALLEN DROMGOOLE.

Everybody said he would go to the bad; everybody expected it of him.

Whether it was the fulfilment of the promise, "As thy faith so be it,"

or whether he felt any conscientious obligation resting upon him not

to disappoint public expectation, nobody knows. Nobody was surprised,

however, when news went over the town that Jim Royal was going to the

penitentiary.

Going to "the pen" at sixteen years of age. Nobody thought of that.

Moreover, the old Tennessee prison contains scores of boys _under_

sixteen, for that matter; and if they do not work satisfactorily, the

lessees of the prison have made no complaint of them; therefore, they

_do_ work satisfactorily; for the lessees are not likely to pay the

State for the privilege of feeding worthless hands. But as for

vagabond Jim, if anybody thought of him at all, it was something after

this wise:

"Safe place. Keep him out of mischief. Protect other people's boys.

Bad influence, Jim's. Town's scourge. Bad mother before him.

Questionable father. Made to work."

Now there were two considerations in this category, concerning which

the public opinion was exactly correct. More so, indeed, than public

opinion is usually known to be. Namely: Jim would "be made to work."

No doubt about that. There were straps for the obstreperous, the

water-pump for the sullen, the pool for the belligerent, the lash for

the lazy, and for the rebellious--the shotgun.

Oh, yes; Jim would be made to work. The town was quite right about

that.

The other consideration, although not altogether so important, was a

trifle more interesting. Jim's "questionable father"!

It was his mother's fault that public _interest_ (?) was not

gratified. And it never forgave the poor outcast for leaving the

world with that seal of secrecy still unbroken. The heart broke, but

not the seal. They cast her off utterly when, poor girl-mother, she

stubbornly refused to reveal the name of her betrayer. To them there

was nothing heroic in the answer, "Because _my_ life is ruined, shall

I ruin his?"

So they treasured it against her in her grave, and against her son

after her, in his grave too, that living, loathsome sepulchre, the

State prison.

But they had surmised a good deal regarding Jim's paternal parentage.

They searched for resemblances, birthmarks, peculiarities of feature,

owning that nature always set her brand upon the bastard, and that the

features, as well as the iniquities of the father, are always visited

upon the illegitimate. If this be the case, Jim must have come of some

strange blood. And yet, knowing him and his history, some might have

traced the poor mother in the boy, although of that mother he knew

very little. He had been told--oh, yes, he had been told--that she was

found in a garret one December morning with a vagabond baby nursing at

her dead breast. And old Nancy Piatt, the only one who ever seemed to

dislike talking to the lad about it, had told him that she was "a

pretty corpse, as pretty as the grave ever held," and that the dead

lips wore a smile, those dead lips that never would, and never could,

give up their pitiful secret. Poor lips; death had granted that which

life denied them--a smile. Stubbornness, the town gossips called the

woman's silence. In other circumstances it would have answered to the

higher term of fidelity, or, perhaps, heroism. Jim was very like his

mother, old Nancy said, despite Dame Nature's habit of branding.

Surely Nancy ought to be authority, for when the boy was left, at two

months old, on the town, old Nancy Piatt, a drunken old crone, who

washed the clothes of the rich all the week, and drank her earnings

Saturday evenings, was the only one who offered to "take the cub" whom

the authorities were ready to give away.

A sorry chance had Jim, although he never realized that. At ten he

could drink as much liquor as Nancy herself, and outswear the ablest

lawyer in the town. At twelve he could pick a lock better than a

blacksmith, and was known as one of the most cunning sneak thieves in

the place. At fourteen he beat a little boy of eight unmercifully.

(Did anybody expect old Nancy to tell him that was the crown crime of

cowardice?)

Then someone suspected Nancy of a crime. One of those nameless crimes

concerning which the law is very jealous, not considering the slander

prevented, the "good name preserved," and the disgrace averted. All in

high circles, and all set in the scale against a useless little

baby,--a wicked little illegitimate baby, that is so heartless as to

be born, and thereby bring a world of trouble upon wealthy and

respectable people.

That old Nancy--for handsome considerations--had made away with the

selfish baby, Jim knew as well as anybody. And when he was offered

quite as handsome a sum to tell all he knew about it, his reply was to

plant his fist in the eye of the man who had made the offer. Not that

he cared for the cause the babe's coming had disgraced. He only meant

to stand by old Nance, and not all the money in the county's coffers

could have forced his lips to speak that which would hurt her. He was

afterward arrested and brought before the magistrate, together with

Nance, and swore, not by the calendared saints,--he hadn't made their

acquaintance,--but by "George," by "Gum," by "Gosh," and even by God

himself that he knew nothing at all about the matter. They knew he was

lying, but there was no way to prove it, as he attempted no dodge. He

was merely ignorant. Nance hadn't asked him to do this; she knew he

would do it if necessary. She had not attempted to win his love, his

confidence, or his gratitude. Perhaps she believed, in her blind way,

that these things are born, not won, like respect, and honor, and

admiration. He was fifteen when this happened. At sixteen Nance died

from the effects of a blow from a policeman's club while trying to

arrest her. Two weeks later the policeman died from the effects of a

blow from Jim's club while trying to protect old Nance. Two months

later the prison door closed on Jim, and the town took breath again in

a long, relieved sigh of "_Safe at last!_" As if vagabond Jim's

salvation had lain a weight for sixteen years upon their consciences.

It was certainly the face of a hardened creature that followed the

sheriff to the railroad station that June morning. June, sweet, old

love-laden, rose-burdened June. Of all the year to give up one's

freedom in June. And how many years before he would breathe the free,

rose-haunted air of another June. Twenty. Why, the twentieth century

would be dawning before he would be free again. Would his face be any

the less hard at the expiration of his term? _The penitentiary isn't a

hotbed of virtue_, and Jim wasn't wax. Nobody wasted any hopes on

him,--except the lessees, who, finding him able-bodied, young, and

healthy, sent him to the Branch prison to dig coal.

There an old gray-bearded warden offered a plea for his youth, and a

protest against the associations of the Branch, and was promptly

reminded that the Tennessee State prison was not a reformatory

institute, but that it had been leased as a financial speculation,

which was expected to yield at _least_ ten per cent. on the money

invested by the lessees.

So Jim went to the coal mines in the mountains, leaving his life, his

poor, puny sixteen years of dust and degradation, behind him. If there

was anything of brightness, any softening memory, any tender touch of

the human--_dream_ touches are they to the castaway--which Jim carried

with him, it was the memory of old Nance, drunken, filthy, murderous

old Nance, and the face of the gray-bearded warden who had lifted his

voice in his behalf.

It was noon of a day in June, early in the eighties, that Jim trudged

across the coal-sprinkled ridge upon which rose the great gray,

weather-beaten, rat-infested fence, which was dignified by the name of

stockade. To go out of life into a dungeon like that, and at noon of a

day in June. That Jim made no sign was accredited to his hardness of

heart. That, having registered and heard an official sneer at the

name, Jim Royal, and having passed through the hands of the barber,

and being duly entered at last among the State's hired help, and

dropped down on his ill-smelling bunk, a rat came and gnawed his ear,

and the vermin crawled unmolested over him, and still he gave no sign,

was set down to the account of his laziness.

"He won't be vicious," the warden said, "he is too lazy," and he

thought yearningly of the raw-hide lash hanging in the office. That

the stupor might be the result of weariness had never once suggested

itself. If it had, why still there was the lash. The lessees' ten _per

cent_. must be gotten out of that herd in the stockade, even if it

should be necessary to beat it out.

But when, the next morning, Jim fell into his place as brisk as any,

the warden began to waver between the lash and the pool. If he did not

need the one, he was fairly seen to require the other. All of them

needed some one, may be two, of the prison's medicines, and the warden

made a special point of spying out the diseases of new arrivals, and

applying the remedy as soon as possible. It told them, more plainly

than words, precisely the manner of treatment they were to expect in

case of any appearance of any of the several moral diseases with which

all convicts, young, old, rich, or poor, were supposed to be

afflicted.

Therefore, the warden "had his eye on Jim." And when the gang started

from the stockade across the black, coal-dusted mountains, to the

blacker mine beneath, he called to the new arrival, draining the last

of some sloppy coffee from a dingy tin cup at the greasy, board table

of the shed room that served for dining-room, and laundry, during the

week, and for chapel on Sundays.

"Come here, sir; what's your name, sir? At least what one did you

leave on the book out there?"

"The only one I've got," said Jim. "The clerk down there made it to

spell Royal."

"Royal." A sneer curled the lips of the official. "Here Black"--to the

guard,--"add this royal renegade to your company. Here, you fellow,

fall into line here, and be quick about it."

To Jim, accustomed from the day his dead mother's nipple had been

taken from his toothless gums to having his own free will, the surly

command came like a threat. He hesitated.

"Will you come, you bit of carrion, or shall I fetch you?"

Jim stood like a young lion at bay. His hands unconsciously drew up

into fists; one foot moved forward; the prisoners stood in wondering

groups, some recalling the day, five, ten, fifteen, aye, even fifty

years before, when they, too, had thought of defence. They, too, had

stood at bay. But they had learned the folly of it, and they knew Jim

would learn too; but still they half hoped he would get in that one

blow before the lesson began.

Such fists! such strength! And he came on like a young tiger, his eyes

ablaze, his nostrils quivering, his arm poised, his full chest

expanding, perfectly aware the officer was feeling for the pistol at

his belt, when, quick and noiseless, a small hand, white and delicate

as a woman's, reached out and drew the clenched fist down; a soft

voice, softened by despair, said: "It isn't any use; they'll down you

at last, and you only make it harder."
