URINARY CALCULI. 



453 



On t/te lamince of vesical and renal calculi, and on their 

 quantitative analysis. 



In the analysis of urinary calculi it is of the greatest im- 

 portance to observe the order in which the different laminae 

 were deposited, and in connexion with this subject, and with 

 the relative proportion in which different sorts of calculi occur, 

 we may especially refer 1, to Brand's 1 paper on the urinary 

 calculi in the Hunterian Museum ; 2, to Marcet 2 on the calculi 

 at Guy's Hospital; 3, to Wood 3 on the calculi at the Canter- 

 bury Hospital, the Windmill Street School, and Mr. Cross's 

 collection; 4, to Yellowly, 4 and 5, to Marcet, for their account 

 of the Norwich Hospital collection ; 6, to Henry 5 on the Man- 

 chester collection ; 7, to Smith on the Bristol collection ; 8, to 

 Rapp 6 on the Swabian collection ; 9, to Lecanu and Segalas? on 

 Segalas's collection; 10, to Scharling on the calculi in the 

 Copenhagen Museum ; and, 11, to Taylors on the calculi in the 

 Museum at St. Bartholomew's Hospital. 



The following table affords a view of the relative proportions 

 in which the most common calculi occur :
