 four lemons in the twenty-four hours. 



From the second experiment, upon a healthy boy, set.

 sour cream, and honey; that the natural deposit, varying 

 from three quarters of a grain, to one grain and a half, 

 totally disappeared, upon the use of a diet chiefly ani- 

 mal; and was only observable, where indigestion of the 

 acid kind supervened upon so unusual and unnatural a 

 regimen. 



The third experiment, we find merely corroborative of 

 the former. But, from the fourth, as well as some others, 

 we learn, that even acid ingesta, or lemon juice, where the 

 action of the skin is vigorous, and assisted by exercise, 

 contribute very little to the increase of the uric acid de- 

 posits of urine; and from this and other experiments, insti- 

 tuted upon himself, as well as others, Avhile under the in^ 

 fluence of sudorific medicines, he concludes, that the uric 

 acid passes off, (in part at least,) by the skin, under the 

 circumstances already mentioned. 



From the fifth, on the same boy, that, whilst living for 

 twenty-four hours, chiefly on beef and salt fish, (though 

 Avith an allowance of small beer and potatoes,) no deposit 

 of uric acid took place; but, upon turning over, for the 

 saine interval of time, to bread, milk, apple-duuiplings 

 and sugar, it amounted to one grain.
