The transference of the _Filaria bancrofti_, whose presence in the human

body in the adult stage is associated with various diseases of the

lymphatics, the most pronounced of which is the terrible elephantiasis,

is due to more than one species of gnat or mosquito. It is true that no

one has ever seen the actual transference of the _Filaria_ from the

biting organs of the _Culex_, _Anopheles_, _Panoplites_, or _Stegomyia_

into the human body, but the circumstantial evidence is so strong that

on it any jury would convict. Noè and Grassi have demonstrated a similar

mode of infection for the _Filaria immitis_, which exists in the adult

stage in such incredible numbers in the cavity of the right side of the

heart of dogs, especially in tropical and in sub-tropical countries,

that it is difficult to see how the circulation can be maintained at

all. It is therefore interesting to note that the proboscis of our

common house-fly frequently harbours a larval nematode which has been

described by Carter[12] under the name of _Habronema muscæ_; and again

(if it be the same species) by Generali[13] under the name _Nematodum

sp._ (?), and again by Piana,[14] who is inclined to think it is the

larval form of _Dispharagus nasutus_ (Rud.). What the further history of

this parasite is we do not conclusively know, but, judging by

analogy--and in the case of the grosser parasites it is not always wise

to do that--the nematode probably develops in some higher animal which

eats the fly. Piana brings forward a good deal of evidence that this is

the domestic fowl.

Another parasite which attacks flies is the fungus or mould _Empusa

muscæ_, whose growth is fatal to the insect. The hyphæ penetrate into

the body, and as they grow weaken the fly until it is unable to lift a

leg, but remains glued by its viscid feet to the object upon which it

rests. The fungus spreads and radiates out in all directions, covering

the fly as with a velvety pile, and giving off countless minute spores,

which are blown away, to alight, if they are lucky, on a further victim.

I think enough has been said to prove that flies are a very real danger

to our community. I have refrained from giving the appalling statistics

of our infant mortality, partly because of the difficulty of

discriminating between the claims of the flies and those of other

agencies which affect the lives of our babies--_e.g._, the insurance

companies which do a large trade in insuring infants. Legislation has

not attempted to control the latter. Sanitation might do much to destroy

the former. In well-administered towns slaughterhouses no longer ‘fill

our butchers’ shops with large blue flies’; they have been replaced by

abattoirs, under proper inspection. Stables should also be segregated or

controlled. The practice of backing the mansions of Berkeley Square by

stable yards should either be given up, or the manure-heaps in which the

flies breed should be under cover so close as to prevent the access of

the fly. A layer of lime spread over the manure effectively prevents

the fly laying. Creolin, in its cheap commercial form, is also

recommended, sprayed over the manure-heaps every two or three days. It

not only deters flies from ovipositing, but should they succeed in doing

so it kills the resulting larvæ.[15]

Ross has shown us how to clear Ismailia of malaria; the Americans have

rid Havana, for the first time in a century, of yellow fever; the same

could be done with flies, if only the people liked to have it so. The

motorcar, with all its destruction of nervous tissue, its prevention of

sleep, its danger to life and to limb, has one great merit--it affords

no nidus for flies.

CAMBRIDGE

‘_Our dear Cambridge._’

COWLEY:

‘On the Death of Mr. William Hervey.’

The grant of a charter to the Victoria University in 1880 marked the

beginning of a new era in English education. Not to speak of Scotland

and Wales, there are in England to-day six Universities which bring the

new learning and the old to the very doors of the vast populations which

surround their seats. Birmingham claims the Midlands; Manchester,

Liverpool, Leeds, and Sheffield instruct the manufacturing and

commercial centres of the North; while the University of London, full of

new aspirations, does its best for the huge and somewhat apathetic

population of the capital. The calculated prodigality of the State

endowments of Germany, the individual generosity of the citizens of the

United States, the vigour of the young Universities of Canada, have

smitten the national conscience, if not with shame, at least with fear.

But, while so powerful a lever as the dread of industrial decay may have

been necessary to overcome the intellectual inertia of the country, the

consequent impetus given to the study of science and (it may be hoped)

of letters is not dying away, but rather taking permanent shape; and it

is now impossible to say, as was said in 1903 by one of the members of

the Mosely Educational Commission, that ‘in this country ... we seem to

be doing nothing for its own sake, and least of all in education.’

The new edition of the ‘Endowments of the University of Cambridge’

suggests other, though kindred, reflections. The book has for its basis

a series of documents, beginning with the year 1293, and ending with the

year 1904. The learned Registrary has prefaced the account of each

bequest with an explanation, and, by his discriminating comment, has

invested his material with something of that charm which characterizes

all his work. In one aspect his book serves, and is intended to serve,

as a history of the progress of education in Cambridge; and the large

amount of new matter which has been incorporated since the previous

edition of the ‘Endowments’ in 1876 is, in this aspect, highly

satisfactory. Yet, though it is a mistake to suppose that the flow of

benefactions to the ancient Universities has entirely ceased, the fact

remains that Cambridge has twice appealed--once in 1898, and once again

in the spring of 1904--for help, without which she cannot meet her

national responsibilities. Oxford has at last been constrained to

confess that she is in a similar, if not yet so dire, a strait; and it

is easy to understand the effort which it has cost her, as well as her

sister University, to sue _in formâ pauperis_.

In truth, the neglect, almost absolute, of Oxford and Cambridge, while

the new Universities are finding generous benefactors, either leads to

the conclusion that the old Universities are condemned and found

wanting, or has its origin in a profound misconception of their efforts

and resources. It may be urged that neither alternative is true; that

the needs of the new Universities are more urgent, and that the needs of

Oxford and Cambridge will in turn receive attention. But a delay of a

few years may in these days involve damage which will not be repaired

for more than one generation. Of Cambridge, at any rate, it is asserted

that she is at the end of her means, that in the last forty years she

has, in her efforts at development, strained her resources to the

utmost, and that without assistance, which, to be effectual, must be

both prompt and generous, no further advance is possible. Science has

emptied the University chest, yet, as the late master of Trinity Hall

said, ‘Science is still hungry and aggressive.’ As the result of her

straitened resources Cambridge can no longer satisfy the just demands

either of science or of letters. When we compare this state of things

with that in Germany, where the University of Berlin enjoys a State

endowment of £170,000 per annum, or in the United States, whose

Universities have received from private benefactors alone £42,000,000

sterling in the last thirty years, apart from large funds provided by

the State, we are forced to recognize that much yet remains to be done

in England.

It is not difficult to suggest some reasons for the comparative neglect

of the older Universities in the matter of benefactions. In the first

place, neither of them can appeal to local patriotism; and an appeal on

the wider ground of national efficiency is not so easily nor so

effectively pushed home. Next, it is hard to imagine that a University

whose colleges enjoy a corporate income of something like £300,000 a

year can be in serious want of funds. Moreover, if this deficiency

really exists, it is generally regarded as the result of the squandering

of revenue on an extravagant system of ‘prize fellowships’--that is,

fellowships given as the reward merely for a high place in examination,

and held by barristers, doctors, and civil servants, professors and

lecturers in other Universities, and even successful men of

business--persons who do not contribute in any way to the efficiency of

the University as a teaching or as an investigating body.

* * * * *

We propose briefly to examine the University balance-sheet, the college

system, and the question of the fellowships, and to endeavour to give

the candid inquirer some ground for a judgment on the claims of

Cambridge. But we must first discuss what is perhaps the most serious

obstacle to the satisfaction of her needs. This obstacle is the belief,

apparently ineradicable, that the older Universities teach and care for

nothing but the ancient languages, theology, and mathematics. For the

persistence of this belief the daily press and public speakers are in a

great measure to blame. Scarcely a week passes without an allusion which

betrays, if not a culpable levity, a most unfortunate ignorance.

Cambridge men have listened with amazement to the covert attacks on

Cambridge science, and have wondered how long it may be before Cambridge

letters are also disparaged. Of late, too, another note has been heard;

and, notwithstanding the just aspiration of the new Universities to a

many-sided activity, alike in the literary and scientific fields, an

attempt, which must be stigmatized as ungenerous and illiberal, has been

made in the press and on the public platform to limit the functions of

the ancient Universities, and to drive them back into the grooves of the

thirties and forties, from which Cambridge, to say nothing of Oxford,

has so completely escaped. Whatever the reason may be, it is at least

certain that Cambridge is frequently written and spoken of as if she

were still the Cambridge of 1850.

It has been suggested, even in responsible journals, that Oxford and

Cambridge would do well to keep to the older lines of education, and to

leave newer studies to their younger rivals. The obsession of men’s

minds by an ideal which passed away half a century ago can alone account

for the impression that the policy of restriction to the ancient

learning is in any way possible, or has been possible for these fifty

years. Those who know Cambridge may well be astonished that responsible

persons should gravely speak of the University of Newton and Charles

Darwin, of Maxwell and Rayleigh, as still shrouded in medieval shadow.

It cannot be too often repeated that since the Commission of 1850, or

rather since the promulgation of the new statutes in 1856, the

University has advanced without pause to claim as her own the whole

field of modern knowledge; and that it is the rapidity of her advance

which has depleted her treasury. The state of things before 1850 need

here be referred to only for purposes of contrast. The only avenue to an

honours degree was then the Mathematical Tripos, or, for students of

classics, the Mathematical combined with the Classical Tripos. Science

formed no part of the regular course of instruction. Adam Sedgwick

himself, pre-eminent geologist as he afterwards became, knew nothing of

geology when admitted to his professorship. When he was appointed to his

chair, classics, mathematics, and, in a less degree, theology and law,

were well endowed; but effective provision for modern studies or for

science there was none. In 1851 was founded the Disney professorship of

archæology, and the creation of this chair may fairly be considered to

be the first step towards the recognition of the sciences of ethnology

and anthropology. The imperial value of ethnological and anthropological

research is incontestable, and to this research no more important

contribution has been made than by the bands of Cambridge travellers and

students.

Mention has been made in the first place of the studies more closely

related to the ‘humanities,’ because it does not seem generally to be

realized how thoroughly even the ancient learning is to-day imbued by

the scientific spirit. But, so early as the year 1851,[16] new avenues

to an honours degree were opened by way of the Moral Sciences Tripos

(embracing at present psychology, logic and methodology, political

economy, ethics, metaphysical and moral philosophy and psychophysics),

and the Natural Sciences Tripos (embracing chemistry, physics,

mineralogy, geology, botany, zoology, human anatomy, and physiology). In

1857 the Sadlerian professorship of pure mathematics was founded by the

consolidation of an old endowment; and Cayley was the first occupant of

the chair. In 1863 the block of buildings known as ‘The Museums’ was

commenced, with a view to providing accommodation for the professors of

the natural sciences; additions were made to the original buildings in

1877, 1880, 1882, 1884, and 1890, as new branches of science became

important. In 1858 the ‘Civil Law Classes’ were replaced by the Law

Tripos; the professor of civil law and the Downing professor of the laws

of England were given a colleague by the creation of the Whewell

professorship of international law in 1867; and the Law School has since

1904 possessed a worthy habitation, built partly at the expense of the

University, partly by the help of eminent Cambridge lawyers, and

completed by the generous donation of the law library by Miss Squire. In

1866 the professorship of zoology was founded.

The School of Medicine has grown continuously; and its progress is

associated with the great names, to mention no others, of Sir George

Humphry, Sir George Paget, and Sir Michael Foster. In 1883 were founded

the professorships of surgery, physiology, and pathology. The diploma of

public health was instituted in 1875, and the diploma in tropical

medicine--the first of its kind in the kingdom--in 1904. The latter

diploma is destined to a brilliant future in Cambridge; and the

University, together with the schools of tropical medicine in London and

Liverpool, is doing much to raise the scientific standard of research

in a study so vitally important to the teeming populations of our

tropical possessions. The students attending the School of Medicine in

Cambridge number nearly four hundred, despite the high standard of the

attainments necessary for qualification. In 1904 important new

buildings, with provision for bacteriology, pathology, and public

health, were opened by the King.

The year 1869 was marked by the foundation of the Slade professorship of

fine art, and the professorship of Latin. The endowment of the latter

chair is but £300 a year, half provided by the University and half by

the friends of the late Dr. Kennedy, the famous headmaster of Shrewsbury

School. That the University should have had to wait till 1869 for the

foundation of a chair of Latin, and that the parsimonious contribution

of £150 a year was all that could be spared towards the stipend of the

professor, scarcely lends colour to the prevailing belief that the

University, kindly and naturally as she may be disposed towards the old

learning, squanders on the teaching of ancient languages resources which

ought to be otherwise employed. In 1875 the Historical Tripos was

founded; and the School of History, starting under the influence of

Seeley, has become one of the most popular avenues to an honours degree.

A professorship of ancient history was founded in 1898.

The Historical Tripos already provided in some measure for the study of

political science and political economy as component parts of a liberal

education. But latterly the need for a more thorough study of economic

conditions has been felt to be imperative for those who look forward to

a career in the higher branches of business or in public life; while, as

regards the professional economist, it has been realized that his work

as a student must be carried much farther than has hitherto been

customary, if he is to attack with success those problems which bring

his science close to reality and to the needs of the practical man. A

Tripos in Economics has therefore been established, the first

examination for which was held in 1905. The advanced portion of it

includes such subjects as modern methods of production, transport and

marketing, trusts, the recent development of joint-stock companies,

railway and shipping organization and rates, banking systems, stock

exchanges, investment markets, international aspects of credit and

currency, tariffs and bounties; and it is expected that, as in the

second parts of most other triposes, a mass of new work, the result of

current research, not yet available in text-books, will be placed before

the students.

The Medieval and Modern Languages Tripos dates from 1886. It provides

for the study of English, French, German, Spanish, Italian, and Russian.

A colloquial test has recently been added. The Semitic Languages Tripos

was established in 1878; the Indian Languages Tripos was founded in

1879, and merged in the Oriental Languages Tripos in 1895. The

University founded a professorship of Sanskrit in 1867; and a chair of

Chinese has existed since 1888. The University possesses the finest

Chinese library in the world outside of China, the gift of Sir Thomas

Wade. Provision is made for the teaching of Arabic, Persian, Turkish,

Hausa, Burmese, and the Indian vernaculars of Bengali, Hindustani,

Marathi, and Tamil. The teaching of living Oriental languages for the

benefit of practical students is carefully co-ordinated under a recently

appointed director of studies; and not only are the most necessary

languages taught in their living forms by competent scholars, but these

latter are assisted by a staff of carefully selected native

_répétiteurs_. Towards the expenses of this work the University

contributes about £2,800 a year. A professorship of Anglo-Saxon was

founded in 1878.

In 1871 the chair of experimental physics was founded, a chair held in

succession by Clerk Maxwell, Lord Rayleigh, and J. J. Thomson; and in

1874 the famous Cavendish laboratory, the munificent gift of its late

chancellor to the University, was opened. The laboratory was designed by

Maxwell; and the chancellor himself, soon after its completion, provided

all the instruments which were immediately required. In 1894 the area of

the laboratory was increased, the cost being defrayed, in part, by a sum

of £2,000 saved by Professor Thomson out of fees received from students;

but the constant pressure on the available space by research students

coming from all quarters of the globe rendered further extension

urgently necessary, an extension which Lord Rayleigh’s generous gift of

the Nobel Prize has now enabled the University to undertake. Astronomy

has a traditional home in Cambridge; and the observatory, which in 1706

found a strange temporary site over the gateway of Trinity College,

began to be built on its present site in 1822. The observatory, which

takes its regular share of the work mapped out for the observatories of

Europe, has received important additions in the shape of both building

and equipment in recent years.

In 1875 the professorship of mechanism and applied science was

established; and in 1878 the first engineering workshops were built in

the University, and fitted with machine tools and other necessary

equipment. In 1894 the new engineering laboratories were opened during

the tenure of the professorship by Dr. Ewing, now director of naval

education. In 1894, also, the first examination for the Mechanical

Sciences Tripos, which gives a degree in honours to students of

engineering, was held. In 1899 the generosity of Mrs. Hopkinson and her

family made possible the addition of a much needed new wing to the

laboratory. The buildings of the department now contain lecture-room

accommodation which seats about 360 students simultaneously, a

drawing-office for a class of ninety, two rooms for elementary heat and

mechanics, a boiler-room, an engine-room with ten heat-engines of

different types, arranged so that the measurement of all quantities

concerned may be systematically made by the students, a large room for

dealing with strength of materials and with hydraulics, a dynamo-room

fitted with various kinds of dynamos, a motor-room fitted with motors of

all the usual types, and several other rooms for special purposes. The

greater part of the staff have had practical engineering experience of

some kind; and it is usual during the long vacation for one or two

members of the staff, as well as a number of the students, to go into a

drawing-office or into works in order to keep in touch with practice.

The school numbers at present more than 250 students, and supplies young

engineers with a scientific training to various public services, as well

as to mechanical and electrical firms.

The University chemical laboratory was built in 1887; and, while

planning it, the professor of chemistry spent some months in visiting

the newest laboratories on the Continent and in America. The importance

of botany has of late years so greatly increased that its study is

represented in Cambridge by a professor, a reader, and two University

lecturers, besides demonstrators, assistant demonstrators, and

attendants. In 1904 botany was housed in a separate building of its own,

the finest devoted to that science in the United Kingdom, and one of the

finest in Europe. The physiology of plants, bacteriological research,

and the cultivation of hybrids and seedlings, are completely provided

for. The extensive botanic garden belonging to the Senate is at the

disposal of the staff and the students, the more distinguished of whom,

after completing their degree course in Cambridge, start on a course of

research in this country or abroad. The importance of the department as

touching agriculture on its scientific side can hardly be overestimated.

The professorship of agriculture was founded in 1899, and endowed for a

term of years by the munificence of the Worshipful Company of Drapers, a

body which, with commendable breadth of view, recognizes alike the

importance of applied scientific instruction for the artisan and of

scientific investigation in all forms of the national activity. The

department of agriculture is conducted on the most practical and

progressive lines. It provides instruction in the principles of

agriculture for the sons of landowners, farmers, and others. It conducts

experiments on crops and live stock, making every effort to secure the

intelligent co-operation of farmers. The University experimental farm,

for the use of which the department is indebted to the generosity of a

member of Clare College, has an area of 140 acres. The County Councils

of Cambridgeshire and nine neighbouring counties co-operate in the work

and assist it by subsidies. The field experiments of the department

extend over ten counties. Parties of farmers visit the experimental

plots every season in order to see the results of the experiments and to

discuss them with members of the staff; and reports which summarize

these results are widely distributed in the districts concerned. Of the

suitability of Cambridge as a site for a school of agriculture, and of

the importance of the work undertaken by the school, it may be well to

leave the late professor to speak for himself.

‘I have but recently become a member of the University, and, like a

good many others, I at one time doubted the possibility of founding

a thoroughly satisfactory school of agriculture in one of the old

English Universities. But I no longer doubt; and as one who, before

coming to Cambridge, was a teacher or student in five British

Universities, I will venture to say that nowhere else do such

opportunities exist. Apart altogether from the exceptional

facilities for the study of science possessed by the University,

and apart, too, from the exceptional practical skill of the farmers

in the surrounding counties, the old University appears to me to be

more disposed to extend a helping hand to agriculture than many of

her younger sisters; and nowhere has a more friendly reception been

given than at Cambridge to the new organization fostered by the

activity of the Board of Agriculture....

‘American experience leaves no room for doubt that modern

scientific methods are capable of greatly increasing the prosperity

of agriculture, and that the farmer has no better ally than the

laboratory worker. But, if we wish to make these benefits ours, we

must cease to be satisfied with imported information; ... we must

aim at securing for agriculture the services of British

specialists, men who will give their whole time to the study of one

subject under the conditions which prevail in our own country. To

the extent of our resources this has been the policy of our

agricultural department in Cambridge.
