and we touched and rubbed the cornea, as sensible a part as it is, without any 

 more sign of his being sensible of it, than if he had been dead. Yet his eye- 

 Hds had a convulsive motion ; his hearing was quite lost; and his feelings though 

 at first he seemed to have some small sense of it when we touched his wound, 

 yet afterwards it was so dull, that we pinched his claws and flesh with pincers, 

 and bored holes through his ears, without his moving, or seeming to be the 

 least sensible of it. It is worth observing, that in the midst of his sleep, being 

 sometimes seized with a convulsive motion of his diaphragm, and other muscles 

 that help respiration, he would bark strongly as if he were awake, and in a little 

 time would be quiet again; so that in less than a quarter of an hour his rest 

 would be disturbed three or four times, with this violent barking. But consi- 

 dering this more attentively, we found that at the very time he barked, he was 

 as void of sense as before; for we could neither make him bark, nor leave off 

 barking, by either beating or pricking him ; but in a little time he would leave 

 off of himself, and return to it again some time after. Thus in 3 hours after 

 the injection, spent in sleeping and barking, he died; and having opened his 

 body after he was dead, we found the bronchia of the lungs filled with a thick 

 froth. 



A few days after, we injected a larger quantity, viz. an ounce of oil of olives, 

 into the jugular vein of a dog, which suffocated him the same moment. — -After- 

 wards, the same quantity of oil of olives, being injected into the jugular vein 

 of a dog, killed him in an hour's time. He was seized with a great sleepiness, 

 snorting, and wheezing, and a bloody water ran plentifully out of his mouth. 

 In this dog, though he did not die immediately, we did not observe the bark- 

 ing, as in the former, but in all that were suffocated by oil, we found their 

 lungs filled with a very thick froth. 



February the 27th, we injected 10 drachms of highly rectified spirit of wine 

 into the crural vein of a dog. The dog died in a very little time very quietly, 

 and as it were with pleasure, licking his jaws with his tongue, and breathing 

 quick, but easily, without barking, crying, or any convulsive motion. In the 

 vena cava, and right ventricle of the heart, the blood was concreted into a 

 great many little hard clots ; which appeared yet more conspicuous and harder 

 in some blood that flowed back from the vein into the syringe. In this dog we 

 found the emulgent artery of the left side to be double. 



March the 2d, we injected three drachms of rectified spirit of wine into the 

 crural vein of a small dog; which made him apoplectic, and as he were half 

 dead. In a little time he recovered from his apoplexy, but became giddy; and 

 when he endeavoured to go, reeled and fell down. Though his strength in- 

 creased by degrees, yet his drunkenness still continued, his eyes were re^i and
