“At this stage of the inquiry we examined the action of light on the eyes of living animals.… We accordingly instituted a series of experiments which were practically very troublesome. We examined the eyes--(1) of the living cat; (2) of the living pigeon; and (3) of the living owl. In all cases the animals were deeply under the influence of chloroform during the experiments.
“1. The Cat.--The animal was securely fixed in Czermak’s rabbit-holder. The skin around the orbit was reflected. The zygomatic arch was snipped through by bone forceps, so as to expose as much as possible of the side of the orbit. The cellular tissue of the orbit was then pushed aside along the superior and the lateral aspect of the eyeball, so as to reach the optic nerve with as little disturbance as possible to the vascular arrangements of the eyeball. On exposing clearly the optic nerve, and staunching hæmorrhage, the nerve was cut through transversely with sharp scissors. When this was done the globe could be pulled downwards, inwards, and forwards, so as to expose a clear transverse section of the nerve. With the head firmly fixed, one narrow clay point was now placed on the cornea, while the other was in contact with the transverse section of the nerve.”--“On the physiological actions of light,” by Dr. McKendrick and Mr. James Dewar.--_Trans. Roy. Soc. Edin._, 1876, p. 160.

“Dr. McReddie (Proceedings of the N.W. Provinces Branch of the British Medical Ass., 1883), after injecting strychnine into dogs, has tried the effects of antidotes on the animals, using inhalations of chloroform, amyl nitrite, atropine, and eserine. He finds that all these remedies are inefficacious, neither preventing the fatal result nor arresting the convulsions.”--_Brit. Med. Journ._, May 19th, 1883, p. 973.
