 culus affections, by causing a separation, and crystalliza- 

 tion of the lithic acid contents of urine, within the body: 

 not pretending, however, to deny the existence of other 

 causes, inherent in the system itself, occasionally produc- 

 tive of similar effects, as has been already observed. 



I shall now proceed to the second part of this inquiry, 

 namely: how far, or in what manner, alkaline matters are 

 conducive to the alleviation of these complaints.
