whole body, a loud noise that he made, notwithstanding his jaws were tied, a 

 great difficulty of breathing and palpitation of the heart, with convulsive mo- 

 tions of almost all parts of his body; in a little time all these remitted, and he 

 was seized with a profound sleep, as if he had been in a lethargy or apoplexy. 

 Having let him loose, he lay upon the ground, without moving or making any 

 noise, in so deep a sleep, that he would not move with beating. About half an 

 hour after, if we beat him, he would move a little, but presently lay down 

 again. After an hour, if we beat him, he would move a little more; and by 

 degrees his sleepiness a little decreasing, in an hour and half or 2 hours time, 

 when he was beat he would make a noise, and walk a little, but seemed very 

 heavy and stupified, and reeled as he went; but as soon as we left off beating 

 him, as if he had forgot every thing that had passed, he presently laid himself 

 down again, and fell asleep. Next day when we viewed the place where he lay, 

 we found a great quantity of fetid excrements, like corrupted blood, or the 

 diluted opium that he had taken; but still his drowsiness continued, and though 

 we beat him with whips, that he ran crying about the room, yet he presently 

 forgot it, and immediately fell asleep again. In this sleepy condition he con- 

 tinued three days, refusing whatever was offered him to eat, or rather not mind- 

 ing that or any thing else. On the fourth day we found him dead: but perhaps 

 he would not have died of the stupifying quality of the opium, if, considering 

 the extreme coldness of the weather, we had put him in a warmer place, and 

 had forced him to have taken some broth. 



February the 8th, we found in the bladder of a tortoise, adhering to its coat, 

 a flat porous stone, about twice as large as a lentil. — February the gth, a drachm 

 and half of common salt, dissolved in an ounce and half of water, was injected 

 into the jugular vein of a dog. After the injection, he was thirsty, and drank 

 water greedily, but in other respects he seemed to be pretty well, and the next 

 day was quite recovered. 



February the 20th, 1679, we injected into the crural vein of a little dog, 



half an ounce of warm oil of olives, which we did with a great deal of difficulty, 



and very slowly, by reason of the smallness of the vein and thickness of the 



liquor. For half a quarter of an hour, that we were injecting the liquor, the 



dog did not seem to be uneasy, or out of order; but after that, he barked, 



cried, looked dejected, and fell presently into a deep apoplexy; so that his 



limbs were deprived of sense and motion, and were flexible any v/ay at pleasure ; 



his respiration still continuing very strong, with a snorting and wheezing, and 



a thick watery humour flowing in great quantity out of his mouth, which was 



sometimes mixed with blood. He lost all external sense: his eyes, though 



they continued open, were not sensible of any objects that were put to them;
