 upon calculi of the mixed kind, having the uric acid, phoa-o(

 of lime, intermixed in their strata. Suffice it to say, that 

 the very dilute marine acid speedily takes up the earthy „ 

 phosphats, leaves the laminae of the uric acid bare and -^

It would be trespassing too rAuch, on the already tried 

 indulgence of the Academy, to go further into the detail 

 of the circumstances necessary to be attended to, and ac- 

 quainted with, to insure success in the application of these 

 principles. These are already tolerably well detailed, in 

 the Connoissances Chimiques. To the gentlemen, profes- i 

 sors in the school of surgery, it more particularly belongs;., 

 and, from the zeal and talents now in full activity there, 

 what may not be expected? Created only the other day, 

 by a Cleghorn, (a name as deservedly as universally re- 

 vered ;) fostered, afterwards, by the-, anxious care and ta- 

 lents of Mr. Dease^ we find it already arrived at a state;, 

 of perfect maturity, and holding out, to the student, ad- 

 vantages, no where to be rivall(^d, if indeed equalled: and, 

 that nothing may be wanting, to a complete medical, as 

 well as surgical education, establishing a chair of botany,,
