pared according to Dr. Faulkner's proportions. No crys- 

 tallized appearance, after seven days. This result we might 

 well expect, fi-om the relative large proportion of its al- 

 kaline salt; having already seen equally good effects, from 

 half an ounce only, of Kinsley's soda water, containing a 

 mere fraction of alkaline matter. 



EXPERIMENT XI. 



To three ounces of urine, were added two grains of the 

 common salt of tartar of the shops; containing, accord- 

 ing to Mr. Kirwan, 0,82 of alkali. The same results, as 

 in the former experiments, even aftei' six days. 



EXPERIMENT XII. 



Having no pure mineral alkali, three grains of the common 

 crystallized soda of the shops, containing, according to 

 Mr. Kirwan, 0,64 of alkali, were added to four ounces of 

 urine. The result as in the former: Avhich was equally 

 produced, by two grains only; and, perhaps, would have 

 been equally so, by one. 



Wishing to be more fully convinced, that the very large 

 proportion of disengaged carbonic acid gas, in our soda 

 waters, did not counteract the usual alkaline effects:
