It is not difficult for us to see that sports and games and

play help to physical development, but it is not so plain that

they may be made to develop the best qualities of character.

It is a fact, however, that all the important elements of

character are tried out in games and sports. Enthusiasm,

self-confidence, the adventurous spirit, alertness, promptness,

unselfishness, cooperation, quick judgment--all these have

their training and discipline on the game field. They comprise

those fundamental native qualities that have gone to make

humanity what it is. The young should have this training, and,

if of the right kind, it may be made to contribute to the

making of the best kind of character. The same quickness and

accuracy of judgment that enable a boy to win a point in

football may in later life be used to win a battle or save a

business venture. Beyond this, there is of course gained the

strong body that makes work easy and stress less difficult to

bear.

Hall calls attention to the fact that two generations ago,

Jahn, the great builder of German physique, roused the then

despairing German nation by preaching the gospel of strong

bodies. He created a new spirit in Germany, and the whole

nation was aroused and seized with an enthusiasm for outdoor

games and sports, and there arose a new cult for the body. His

pupils sang of a united fatherland and of a stronger race. The

Germans are in the habit of reminding us that it was about one

generation after Jahn that the German Empire was founded and

Germany became a world power.

Every argument for the physical training of boys applies with

equal force to girls. Women need to be physically as strong as

men. No race will remain virile and progressive unless both the

fathers and mothers have the physical stamina that produces

healthy, vigorous offspring. In this age, when women are going

out into the world to compete with men it is highly important

that they be physically strong if they are to stand the stress

successfully. It was from rough barbarians, the rude war-loving

Teutonic men and women described by Tacitus, that the

Anglo-Saxon race inherited those splendid qualities of mind and

body that have made their descendants masters of seas and

continents.

It has been objected that gymnastics and field sports make

girls coarse and mannish. The exact opposite has been found to

be the case. It has been observed in colleges that when young

women are properly led, their sports, in place of making them

mannish, have a marked refining influence. They care more for

correct posture because this is made one of their tests in

athletic sports. They develop better manners and a new sense of

pride in their appearance. They soon learn to avoid slang, loud

talking and boisterous behavior. In the University of Chicago

where they have excellent training, many of the girls have said

that they came to have a new sense of dignity and to care more

for their personal appearance.

They also develop the finer elements of character, a

cooperative spirit, obedience to commands, patience,

self-confidence, a spirit of comradeship, a democratic attitude

and an appreciation of good qualities in others wherever found.

All of these esthetic, social and moral qualities, woven into

the texture of the growing character, and with the vigorous

health that the physical training brings, are the best

contribution to the making of the most effective type of the

womanly woman. All games and sports and athletics for the young

should therefore make for refinement and esthetic development.

The state needs now, and will always need, men and women who

have sound bodies and abounding energy.

The harsher phases of the human struggle may pass and wars may

cease, but the old contests of races, nations and individuals

will continue under other forms.

As the race grows older life will become more largely mental.

The increasing complexity of human relations and the more

delicate adjustments that these relations require will bring a

new and finer social order that will make higher demands upon

reason.

While there is no evidence that experience or time or training

will ever change the structure of the brain, it is probable

that we have as yet but imperfectly utilized our mental

possibilities. Stratton says:

Out of the depths of the mind new powers are always

emerging.[2]

[2] "Experimental Psychology and Culture," George M. Stratton.

Back of the mental life, and making it possible, are the

energies of the body, the functioning of the animal in man,

which in the brain are changed to the higher uses of the mind.

The ability to execute, to act effectively, to do and keep

doing, to do the work of the professional man, the banker, or

the scientist, all this is primarily physical, and from top to

bottom of man's activities the physical test is applied. With

the mental and emotional strain of civilized life goes the

physical strain which is the other half of the struggle, and

which now and always is both mental and physical. The Greeks

recognized this unity of mind and body twenty-five hundred

years ago and their results remain unmatched by any race.

They saw that the thought-out movements of physical training

resulted in mental training and this law of mental development

through physical training was a fundamental principle in their

educational plan.

The nation that will again make this an ideal will produce a

finer race of men, and other things equal, will excel in all

that makes a people great.

EDWARD JENNER AND VACCINATION

BY PROFESSOR D. FRASER HARRIS, M.D., D.Sc.

DALHOUSIE UNIVERSITY, HALIFAX, N. S.

WE are so exceedingly apt to take our blessings as a matter of

course that at the present time a large number of us have quite

forgotten, and some of us have never known, what a terrible

disease smallpox is and from how much suffering national

vaccination has saved us. But even many of us, who may not be

included amongst those who know nothing of smallpox, do come

within the group of those who know next to nothing of the life

and work of Dr. Edward Jenner. A number of persons think he was

Sir William Jenner, physician to Queen Victoria.

An infectious or communicable disease is one caused by the

admission of some form of living matter into the body of a

human being or of a lower animal. All diseases are clearly not

communicable in the sense that they are due to the presence of

living things. Indigestion, for instance, I can not communicate

to my neighbor, however serious my dietetic indiscretions.

Now, while the actual microorganisms causing many of the

infectious diseases have been discovered in these recent days

through the agency of the microscope--one of science's most

valuable gifts to suffering humanity--a few diseases

undoubtedly infectious have, even up to the present time, not

had their microorganic causes discovered. Smallpox or variola

is one of these. The term variola is from the Latin varus, a

pimple.

The name Small Pox, which first occurs in Holinshead's

"Chronicle" (1571), was given to this disease to distinguish it

from the Great Pox or syphilis, the French disease, or Morbus

Gallicus which attained the proportions of an epidemic in

Europe about 1494. The expression "The Pox" in the older

medical literature always refers to the Lues Venereal The word

"pox" is the plural form of pock; the spelling "pox" is

phonetic; "pocks" is the correct form.[1]

[1] Thus the following expression in Galt's "Annals of the

Parish" is justified--"My son Gilbert was seized with the

smallpox and was blinded by THEM for seventeen days."

Smallpox is unquestionably a highly infectious or communicable

disease, and in the language of a past day, there is a virus or

poison which can pass from the sick to the unaffected; when

this transference occurs on a large scale we speak of an

epidemic of smallpox. As Sir William Osler truly says, "It is

not a little remarkable that in a disease, which is rightly

regarded as the type of all infectious maladies, the specific

virus still remains unknown." The same, however, is true of the

common diseases of scarlatina, measles and chickenpox. Of some

diseases, the virus is a bacillus or coccus, excessively minute

fungi recognizable only under the microscope; but the

bacteriologists are now beginning to speak of viruses so

impalpable that they, unlike ordinary bacteria, can go through

the pores of a clay filter, are filter-passers, that is are of

ultra-microscopic dimensions. Some authorities conjecture that

the virus of variola belongs to the group of filter-passers.

The virus of smallpox, however, is very resistant and can be

carried through the air for considerable distances; it clings

for long periods to clothes, books, furniture, etc.

I shall not now digress to give the clinical details of a case

of smallpox; the eruption may be slight or it may be very

extensive. It occurs in three forms, discrete, confluent and

hemorrhagic. The most dangerous form of smallpox is the

confluent, in which the face and arms particularly are covered

with large pustular areas of a most disfiguring appearance.

The disease called chickenpox, or varicella, has no

relationship to smallpox and does not protect from it, nor does

smallpox protect from chickenpox.

HISTORY OF SMALLPOX

There seems very little doubt that the home of smallpox was

somewhere on the continent of Africa, although it is true that

there are traditions pointing to its existence in Hindustan at

least 1000 B.C. One Hindu account alludes to an ointment for

removing the cicatrices of eruption. Africa has certainly for

long been a prolific source of it: every time a fresh batch of

slaves was brought over to the United States of America there

was a fresh outbreak of smallpox.[2] It seems that the first

outbreak in Europe in the Christian era was in the latter half

of the sixth century, when it traveled from Arabia, visiting

Egypt on the way. The earliest definite statements about it

come from Arabia and are contained in an Arabic manuscript now

in the University of Leyden, which refers to the years A.D. 570

and 571. There is a good deal of evidence that the Arabs

introduced smallpox into Egypt at the sacking of Alexandria in

A.D. 640. Pilgrims and merchants distributed it throughout

Syria and Palestine and along the north of Africa; then,

crossing the Mediterranean, they took it over to Italy. The

Moors introduced it into Spain whence, via Portugal, Navarre,

Languedoc and Guienne it was carried into western and northern

Europe. The earliest physician to describe smallpox is Ahrun, a

Christian Egyptian, who wrote in Greek. He lived in Alexandria

from A.D. 610 to 641. The first independent treatise on the

disease was by the famous Arabian physician, Rhazes, who wrote

in Syriac in 920 A.D., but his book has been translated into

both Greek and Latin. The first allusion to smallpox in English

is in an Anglo-Saxon manuscript of the early part of the tenth

century; the passage is interesting--"Against pockes: very much

shall one let blood and drink a bowl full of melted butter; if

they [pustules] strike out, one should dig each with a thorn

and then drop one-year alder drink in, then they will not be

seen," this was evidently to prevent the pitting dreaded even

at so early a date. Smallpox was first described in Germany in

1493, and appeared in Sweden first in 1578.

[2] Osler thinks the pesta magna of Galen was smallpox; Marcus

Aurelius died of it.

The contributions of Sydenham, the English Hippocrates, to the

knowledge of smallpox, are classical.

Throughout the Middle Ages, owing to the very crowded and

unsanitary state of the cities of Europe, smallpox was one of

the various plagues from which the inhabitants were never free

for any length of time.[3] Leprosy, influenza, smallpox,

cholera, typhus fever and bubonic plague constituted the

dreadful group. In most countries, including England, smallpox

was practically endemic; an attack of it was accepted as a

thing inevitable, in children even more inevitable than

whooping-cough, measles, mumps or chickenpox is regarded at the

present time. There was a common saying--"Few escape love or

smallpox." In the eighteenth century so many faces were pitted

from severe smallpox that it is said any woman who had no

smallpox marks was straightway accounted beautiful. Very few

persons escaped it in either the mild or the severe form in

childhood or in later life.

[3] England was by no means exempt, but it was not infection in

the modern sense that Shakespeare meant when he wrote--

"This England,

This fortress, built by Nature for herself

Against infection and the hand of war."

Now it is characteristic of a microorganic disease that a

person who has recovered from an attack of it is immune from

that disease for a longer or shorter time, in some cases for

the remainder of life. This is, luckily, as true of smallpox as

of any of the other acute infections. We do not now need to

enquire into the theory of how this comes about; it is a

well-recognized natural phenomenon. The modern explanation is

in terms of antigens and anti-bodies and is fast passing from

the stage of pure biochemical hypothesis into that of concrete

realization. Persons who have recovered from smallpox rarely

take it a second time; the few who do, have it in a mild form.

It follows, then, that if smallpox is purposely inoculated into

a human being he will for a long time be resistant to the

subsequent infection of smallpox. The fact of smallpox

protecting from smallpox is by no means without analogy in

other diseases. Thus in Switzerland, in Africa, in Senegambia,

it has been the custom for a long time, in order to protect the

cattle from pleuro-pneumonia, to inoculate them with the fluid

from the lung of an animal recently dead of pleuro-pneumonia.

Of course since the time of Pasteur we have been quite familiar

with the inoculation of attenuated virus to protect from the

natural diseases in their fully virulent form, for instance,

anthrax, rabies, plague and typhoid fever.

As it was, then, known to mankind from a very early period that

a person could be protected from smallpox by being inoculated

with it, inoculation grew up as a practice in widely distant

parts of the globe. The purpose of intentional inoculation was

to go through a mild attack of the disease in order to acquire

protection from the much more serious natural form of the

disease--to have had it so as not to have it. A very high

antiquity is claimed for this smallpox inoculation, some even

asserting that the earliest known Hindu physician (Dhanwantari)

supposed to have lived about 1500 B.C., was the first to

practice it. Bruce in his "Voyages to the Sources of the Nile"

(1790) tells us that he found Nubian and Arabian women

inoculating their children against smallpox, and that the

custom had been observed from time immemorial. Records of it

indeed are found all over the world; in Ashantee, amongst the

Arabs of North Africa, in Tripoli, Tunis and Algeria, in

Senegal, in China, in Persia, in Thibet, in Bengal, in Siam, in

Tartary and in Turkey. In Siam the method of inoculation is

very curious; material from a dried pustule is blown up into

the nostrils; but in most other parts of the world the

inoculation is by the ordinary method of superficial incision

or what is called scarification. By the latter part of the

seventeenth century inoculation for smallpox was an established

practise in several European countries into which it had

traveled by the coasts of the Bosphorus, via Constantinople. In

1701 a medical man, Timoni, described the process as he saw it

in Constantinople. Material was taken from the pustules of a

case on the twelfth or thirteenth day of the illness. As early

as 1673 the practice was a common one in Denmark, Bartholinus

tells us. In France inoculation had been widely practiced; on

June 18, 1774, the young king Louis XVI., was inoculated for

smallpox, and the fashionable ladies of the day wore in their

hair a miniature rising sun and olive tree entwined by a

serpent supporting a club, the "pouf a l'inoculation" of

Mademoiselle Rose Bertin, the court milliner to Marie

Antoinette. In Germany inoculation was in vogue all through the

seventeenth century, as also in Holland, Switzerland, Italy and

Circassia. In England the well-known Dr. Mead, honored, by the

way, with a grave in Westminster Abbey, was a firm believer in

inoculation, as was also Dr. Dimsdale, who was sent for by the

Empress Catherine II. to introduce it into Russia. Dr. Dimsdale

inoculated a number of persons in Petrograd, and finally the

Grand Duke and the Empress herself. The lymph he took from the

arm of a child ill of natural smallpox. For his services to the

Russian court Dr. Dimsdale was made a Baron of the Russian

Empire, a councillor of state and physician to the Empress. He

was presented with the sum of 1,000 pounds and voted an annuity

of 500 pounds a year. At the request of Catherine, Dr. Dimsdale

went to Moscow, where thousands were clamoring for inoculation.

The mortality from smallpox in Russia seems to have been still

higher than in the rest of Europe. The annual average death

rate on the Continent at the end of the eighteenth century was

210 per 1,000 deaths from all causes, while in Russia in one

year two million persons perished from smallpox alone. In

England in 1796, the deaths from smallpox were 18.6 per cent.

of deaths from all causes.

A great impetus was given to inoculation in England by the

letters of Lady Mary Wortley Montague, the wife of our

ambassador to Turkey, Edward Wortley Montague, and daughter of

the Duke of Kingston. In 1717 Lady Mary wrote a letter to her

friend Miss Chiswell, in which she explained the process and

promised to introduce it to the notice of the English

physicians. So convinced was Lady Mary of the safety of

smallpox inoculation and its efficacy in preserving from

subsequent smallpox, that in March, 1717, she had her little

boy inoculated at the English embassy by an old Greek woman in

the presence of Dr. Maitland, surgeon to the embassy. In 1722

some criminals under sentence of death in Newgate were offered

a full pardon if they would undergo inoculation. Six men agreed

to this, and none of them suffered at all severely from the

inoculated smallpox. Towards the close of the same year two

children of the Princess of Wales were successfully inoculated;

and in 1746 an Inoculation Hospital was actually opened in

London, but not without much opposition. As early as 1721 the

Rev. Cotton Mather, of Boston (U. S. A.), introduced

inoculation to the notice of the American physicians, and in

1722 Dr. Boylston, of Brooklyn, inoculated 247 persons, of whom

about 2 per cent. died of the acquired smallpox as compared

with 14 per cent. of deaths amongst 6,000 uninoculated persons

who caught the natural smallpox. There was, however, great

popular opposition to the practice of inoculation, and Dr.

Boylston on one occasion was nearly lynched.

While successful inoculation undoubtedly protected the person

from smallpox, sometimes the inoculated form of the disease was

virulent, and certainly all cases of inoculated variola were as

infectious as the natural variety. Inoculated persons were

therefore a danger to the community; and there is no doubt that

such persons had occasionally introduced smallpox into towns

which had been free from the natural disease. At the end of the

eighteenth century, just about the time of Jenner's discovery,

public opinion was strongly against the continuance of the

practice of inoculation, and as natural smallpox had not at all

abated its epidemic character, the times were ripe for "some

new thing."

Now there is a disease of cows know as cowpox or vaccinia (from

the Latin vacca, a cow) which is communicable to human beings.

It is thought to be due to the same virus which in pigs is

called swinepox and in horses "grease." Jenner believed

vaccinia to be the same pathological entity as human smallpox,

modified, however, by its transmission through the cow. For a

long time this view was stoutly resisted, but it has now been

accepted as probably representing the truth. The identity of

vaccinia and "grease" is certainly much more doubtful.

To many of Jenner's contemporaries the view that vaccinia had

at one time been a disease of human beings seemed unlikely; but

we are now in a far better position to admit its probability

than were those of Jenner's time. We have since then learned

that man shares many diseases with the lower animals,

tuberculosis, plague, rabies, diphtheria and pleuro-pneumonia,

to mention only a few. We have also learned that certain lower

animals, insects for instance, are intermediary hosts in the

life-cycle of many minute parasites which cause serious

diseases in the human being, amongst which malaria, yellow

fever and the sleeping sickness are the most familiar.

It appears to have been understood before Jenner's time that

persons who had acquired cowpox by handling cattle, but

especially by milking cows, were immune from smallpox. In the

reign of Charles II. it is well known that the court beauties

envied the dairy-maids because having had cowpox, they could

not take smallpox which all women so dreaded. Dr. Corlett tells

us that the Duchess of Cleveland, one of the King's mistresses,

on being told that she might lose her place in the royal favor

if she were disfigured by smallpox, replied that she had

nothing to fear as she had had cowpox. In 1769 a German, Bose,

wrote on the subject of cowpox protecting from smallpox. In the

year 1774 a cattle dealer, Benjamin Jesty, at Yetminster, in

Dorset, inoculated his wife and three children with cowpox.

None of them ever took smallpox during the rest of their lives

although frequently exposed to its infection. Jesty died in

1816, and it is recorded on his tombstone that he was the first

person who inoculated cowpox to protect from smallpox. Cowpox,

or vaccinia, though infectious for cows, is not transmissible

among human beings, in other words, as a disease of man it is

not infectious. Edward Jenner, the Englishman of Berkeley in

Gloucestershire, was the first person to think scientifically

on the fact that cowpox protected from smallpox. John Hunter

had said to him, "Jenner, don't think, try." Luckily, however,

he did both. Thinking alone avails little, experimentation

alone avails not much, but the one along with the other has

removed mountains. Just as Newton thought scientifically about

that falling apple and reduced our conceptions of the universe

to order, just as Watt thought scientifically about that

kettle-lid lifted by the steam and so introduced the modern era

of mechanical power brought under man's control, so Jenner

thought about and experimented with cowpox until he had

satisfied himself that he had discovered something which would

rid the human race forever of the incubus of an intolerable

pestilence.

It was in 1780 that Jenner set himself to study cowpox in a way

that had never before been attempted, for he was convinced that

in the having had an attack of the disease lay the secret of

the conquest of that world-scourge. He confided in his fried

Edward Gardner about "a most important matter . . . which I

firmly believe will prove of essential benefit to the human

race . . . should anything untoward turn up in my experiments,

I should be made, particularly by my medical brethren, the

subject of ridicule." Luckily he was quite prepared for both

ridicule and opposition; for has not everything new been

ridiculed and opposed? Galileo was opposed, Bruno was opposed,

Copernicus was opposed, Harvey was opposed, George Stevenson

was opposed, Pasteur was ridiculed and opposed, and so were

Darwin, Simpson and even Lister. The physiological inertia even

of the educated has too often blocked the path of advancement:

but Jenner is in illustrious company, a prince amongst the

hierarchy of the misunderstood.
