" infants vomit." It deferves to be here remarked that thefe 

 obfervations are ftated as matter of opinion, and not the refult 

 of any experiment. I determined however to try them as far 

 as polfible by this teft. I took equal quantities of three different 

 kinds of milk, put them into bottles flightly corked, and thefe 

 bottles into water, the temperature of which was kept up by a 

 fpirit of wine lamp as near to 96° of Farenheit as poffible. 

 But after frequently examining each bottle, during the courfc 

 •of the experiment, at the expiration of feveral hours there was 

 not the fmalieft tendency towards coagulation to be perceived 

 in any of them. As ufual, the cream was thrown to the furface 

 thick and adhefive, and entirely feparated from the fluid 

 underneath, which had fomewhat of a grey wheyifh ap- 

 pearance. 



As the matter vomited by Infants is fometimes more adhefive 

 than we might fuppofe cream to be, I fufpeded that the curd 

 might be fo entangled with the cream as to be with difficulty 

 feparated from it ; I therefore colleded a quantity of rich cream 

 from a large quantity of milk of different women, and repeated 

 the former experiment with precifely the fame event. Towards 

 the conclufion I added acids, both mineral and vegetable, but 

 without producing any thing like curd. Indeed I had little 

 doubt, before any experiment was attempted on this fubjedl, 

 that Dr. Young was miftaken in the idea of milk feparating 

 into curds and whey in a certain degree of temperature; for 

 was this fad we fhould every day meet with flagnant milk in 

 the mammas, where it is expofed to the heat of the human body,
