"You may open the abdomens of living cats, guinea-pigs, and rabbits, and apply irritating chemicals to their exposed intestines, causing what you are pleased to term 'peculiar rhythmic movements' and 'circus movements,' but what the unlearned would call violent spasms and convulsions, as was done by Dr. Batten and Mr. Bokenham, at St. Bartholomew's Hospital, last year. You may dissect out the kidneys of living dogs and cats which you have first paralyzed by curare--the 'hellish oorali' of Lord Tennyson's poem, so called because the animal's sufferings are intensified by its use, and it is unable to move a limb, or to bite, scratch, howl, or otherwise interfere with the operator's comfort. You may do this, as was done by Dr. John Rose Bradford, at University College, London. You may infect ninety cats with cholera poison, and bake numbers of them alive, as did Dr. Lander Brunton. You may inoculate the eyes of rabbits and guinea-pigs with the material of tubercle, fix glass balls filled with croton oil--a horribly irritating drug--and stitch them into the muscles of the backs of rabbits, then crush them amongst their tissues, as did Dr. Watson Cheyne, at King's College, London. You may slice, plough, burn, and pick away the brains of monkeys and dogs, as did Dr. Ferrier. You may slowly starve to death animals whose vagi nerves have been cut and stimulated by electricity, as was done by Dr. Gaskell, of this University, in 1878. You may cut out the spleens and livers from living rabbits, pigeons, and ducks, as was done by Dr. William Hunter, of St. John's College, Cambridge, in 1888, or do a thousand other acts which in a coster-monger or a farm laborer would be termed and dealt with as acts of atrocious cruelty, punishable by imprisonment. But you have not learned the cure for a single malady which afflicts the human body." THE MOVEMENTS OF THE TONGUE There is another mode of proceeding by which satisfactory results can be obtained, and which was the only one I resorted to in the beginning and for many years afterwards; namely, the watching of the movements of the tongue.
