the year 1814, under the presidency of Sir Henry Halford, Dr. 

 Yelloly, Dr. Marcet, and other influential members, conceiving 

 that great advantages would result to the Society, and its perma- 

 nence be better secured, by its being incorporated under a Royal 

 Charter, took the proper measures for accomplishing this object. 

 The necessary forms were gone through, and the grant was on the 

 eve of being signed, when an unexpected opposition was suddenly 

 raised by the College of Physicians, who finally prevailed on the 

 Privy Council to refuse the prayer of the petitioners. Dr. Yelloly, 

 however, lived to see the great change which has since taken place 

 in the spirit of the times ; for, in the year 1 834, his favourite scheme 

 was realised, all opposition had subsided, and the Society obtained 

 at once from the Crown the Charter under which it is now consti- 

 tuted as the Royal Medical and Chirurgical Society of London. 



Although Dr. Yelloly diligently availed himself of the extensive 

 opportunities afforded by his public appointments, and had acquired 

 universal respect and esteem by the suavity of his manners and the 

 kindness of his disposition, it is remarkable that he nevertheless failed 

 to obtain more than a very moderate share of private practice. In 

 course of time his family had become very numerous, while his pro- 

 fessional income was by no means increasing in an equal ratio ; and 

 prudential motives prevailing over his attachment to the metropolis, 

 he at length determined to quit London, and establish himself at 

 Carrow Abbey, in the immediate vicinity of Norwich. He resided 

 there during many years, engaged in practice : he was soon elected 

 one of the Physicians of the Norfolk and Norwich Hospital, and in- 

 troduced into that establishment many useful reforms. It was du- 

 ring this period that he undertook the examination of the urinary 

 calculi, of which the Hospital contained a large collection. He com- 

 municated to the Royal Society the result of his labours in a paper 

 which was published in the volume of our Transactions for 1829*. 

 In this paper he gives an account of the structure and chemical com- 

 position of 330 calculi, which had either been purposely divided or 

 accidentally broken in their extraction. The results are arranged in 

 tables, exhibiting, in the order of their superposition from the centre, 

 the consecutive deposits of which each calculus is composed. It ap- 

 pears from these tables, that not less than two-thirds of all urinary 

 calculi consist of the lithates, or have those substances for their nu- 

 clei : whence Dr. Yelloly inferred the probability that a large pro- 

 portion of them owe their existence to the previous formation of such 

 a nucleus, and was led to suspect that carbonate of lime, although
