recovered, and the rest better. 2d, All of them were pretty well ; and they 

 continued so. 



Several dogs, who had eaten of these fish, and especially of the guts and bones, 

 seemed affected in a higher degree than the men. Their illness might perhaps 

 have begun in the night, but was not perceived till next morning. One, in 

 particular, had violent retchings, a paralysis, especially of the hind legs, lay 

 down, rolled, howled, and showed other signs of great pain. More saliva or 

 froth hung about his mouth ; and, when fatigued with struggling, would fall 

 down, and seemingly breathe with great labour. Two of them continued in 

 the same way all day ; tliough others that had eaten as much appeared but 

 slightly affected, their principal symptom being only weakness in the hind legs. 

 It was observed, tliat most of them were troubled with a swelling of the penis. 

 One lay the first day, all the afternoon, without being able to move, but groaned 

 perpetually, and lay in appearance in great anguish. Next day, they seemed 

 all somewhat better, except one, to whom tobacco-juice had been given the 

 day before, to make him vomit : he died in the afternoon. On the 3d day, 

 though the dogs were more free from pain, yet they continued almost motion- 

 less, nor did they begin to eat. On the 4th day, they were all much better, 

 the worst of them running about, and eating his victuals. On the 5th, all of 

 them seemed recovered, one excepted, who had not been so soon or so violently 

 attacked as the others. This remark was made of the men likewise ; to wit, 

 that those who were more slightly and later attacked continued ill as long as 

 the others. Some days after, the same dog became so paralytic in his hind 

 legs, that he could not stand ; but afterwards he recovered the use of them 

 pretty well. -c 



A hog, which had eaten of the offals, died next morning ; as did a perroquet 

 on the 2d day, which had got from his master some of the boiled fish. It will 

 be proper to add, that another hog died, which had fed on the entrails of that 

 fish of which Captain Cook had eaten a bit of the liver ; and that a dog, 

 which about 3 weeks after had eaten of a fish of the same species, died, after a 

 lingering illness, of the same nature with that which had affected others of iiis 

 kind. 



XXXFIII. Exper'imenls on Ignited Substances. By Mr. John JVhiteJmist. 



p. 375. 

 The experiments of Buftbn on ignited bodies seem to j^rove, that when 

 heated to the degree he mentions, they are more ponderous than when cold. 

 The experiments wliich I have made on heated metals, suggest a different idea, 

 and contradict the fact he relates ; so that I am induced to believe, that some 

 circumstance, not attended to, has introduced a mistake in the account this learned
