VIVISECTION.

Although Magendie is rightly considered the true initiator of

experimentation upon living beings, the practice of vivisection is as

old as science itself.

Galien, the physician of Marcus Aurelius (in the second century of the

Christian era), dissected living animals, and yet he is regarded as

having merited his name (_Galenus_, "gentle") from the mildness of his

character. Five centuries before him, under the Ptolemies, Egyptian

experimenters had operated upon condemned persons. So, then, vivisection

is not, as usually thought, a diabolical invention of modern science.

[Illustration: Fig. 1-5 APPARATUS USED IN VIVISECTION.]

In all ages the necessity has been recognized of operating upon animals

that are nearest allied to man, such as the monkey, the hog, and the

dog, and who share with the king of creation the privilege of eating a

little of everything. Claude Bernard, however, had another way of

looking at things. It is true that he especially made researches into

the general laws of physiology, the secret of the vital functions, and

the operation of the various organic systems that constitute living

matter, but his immediate object was not to furnish weapons for the art

of curing. He left to physicians and surgeons the care of drawing

conclusions from his great work in biology, and of acting experimentally

upon animals allied to man in order to found a rational system of

therapeutics. So he preferred to operate upon beings placed low in the

animal scale--the frog especially, an animal that has rendered him

greater service than even man himself could have done. Cold-blooded

animals offer, moreover, the advantage of being less impressionable than

others, and the experiments to which they are submitted present more

accurate conclusions, since it is not necessary to take so much account

of the victim's restlessness. And then it is necessary in many cases to

choose subjects that possess endurance. The unfortunate frog, so aptly

named "the Job of physiology," becomes resigned to living under most

dreadful conditions, and when, through sheer exhaustion, he has

succumbed, his twitching limbs may still he used as an object of

experimentation for twenty-four hours. Thanks are due to nature for

giving so extraordinary a vitality to the tissues of a modest

batrachian! We owe to it the famous experiment of Galvani that led Volta

to the discovery of the pile and what followed it, the astonishing

conquests of electricity and those more marvelous ones still that are

now in their dawn. Science is much indebted to the frog, and may the

homage that we pay him help to alleviate the sufferings that have been

imposed upon this brave animal!

The simple fact that we have just enunciated pleads loudly enough for

the cause of vivisection to make it useless to defend it. No one,

however, has risen to ask for an absolute proscription of it, but it is

only desired that the abuse of an abominable practice shall be curbed.

Does the abuse exist? That is the question, and it may be answered in

the affirmative. Yes, we do sometimes impose useless sufferings upon

animals. It is a culpable folly, a beastly cruelty, to constantly repeat

barbarous experiments with the object of exhibiting a well known

physical fact, a hundred times verified and always the same, when it

would only be necessary to enunciate it. But this is not the place to

expatiate upon the subject. After proclaiming the utility of

vivisection, we give it as our opinion that the practice of it should be

confined within narrow limits. It is not too much to ask that it be

confined to the privacy of laboratories, with the exclusion of visitors,

and to require from students a diploma guaranteeing their knowledge and

giving a programme of researches to be made. It is useless to seek in

the living what a study of the corpse reveals in all its details.

And now, after these preliminary remarks, we present herewith a series

of cuts representing the various apparatus used in the practice of

vivisection, which are taken from a recent work by Claude Bernard. Fig.

1 shows the mode of muzzling a dog with a strong cord placed behind an

iron bit. Fig. 2 shows a method of tying a dog. Fig. 3 is a vessel in

which hares or cats are placed in order to anæsthetize them. Fig. 4

shows the mode of fixing an animal on its side, and Fig. 5 the mode of

fixing him on his back. Fig. 6 shows a dog fixed upon the vivisecting

table, and Fig. 7 a hare secured to the same. Fig. 8 exhibits the

general arrangement of a vivisecting table, properly so called. Fig. 9

shows (1) an anæsthetizing muzzle applied to a dog, and (2) the

extremity of the apparatus in section. Fig. 10 shows how the muzzle is

applied for anæsthetizing, and gives the details of construction of the

chloroform box. Fig. 11 exhibits the arrangement of the apparatus used

for holding the animal's jaws open upon the vivisecting

table.--_L'Illustration_.
