rarely found in a separate form in calculi, is not an unfrequent con- 

 comitant of phosphate of lime. With the assistance of Dr. Prout 

 and Mr. Faraday, he ascertained the presence of carbonate of lime in 

 some of the specimens which were not previously supposed to contain 

 it ; a result which was confirmed by the analysis of several calculi 

 from the collection of the Hunterian Museum, and also from the 

 Museum of Guy's Hospital. 



He presented to the Society, two years afterwards, a sequel to this 

 paper, recording, in a tabular form, the analysis of SS5 additional 

 specimens, Avhich had, in the interval, been divided*. The most re- 

 markable fact noticed in this memoir, is the i^resence of silex in a 

 few specimens. Dr. Yelloly finds reason to believe that the ave- 

 rage number of calculous disorders occurring in Scotland has been 

 much underrated ; that, on the other hand, the proneness to these com- 

 plaints is very sm.all in Ireland ; and that, on the whole, a much larger 

 proportion of calculous cases occurs in towns than in the country. 



For some years before his death. Dr. Yelloly had relinquished 

 practice, and resided at Woodton Hall, near Bungay ; his attention 

 being chiefly turned to agricultural pursuits. From thence he re- 

 moved, about two years ago, to Cavendish Hall, in the neighbour- 

 hood of Clare, in Suffolk ; where, in February last, his valuable life 

 was suddenly terminated by an attack of apoplexy, while taking an 

 airing in his carriage. 



The Earl of Macclesfield was born on the 24th of February, 

 1755. He married, 25th of May 1780, Mary Frances, daughter and co- 

 heir of the Rev. Thomas Drake, and died last March at the advanced 

 age of eighty-seven. He was Lord Lieutenant of the county of Ox- 

 ford. In former times he used often to attend the meetings of the 

 Royal Society ; to which, indeed, it was natural that he should feel 

 something of an hereditary regard, descended as he was from one of 

 our former Presidents, 



Among those Fellows whose loss by death this Society has to de- 

 plore since my last annual address, Mr. Gage Rokewode should 

 not be forgotten. 



This gentleman, long so well known for the admirable manner in 

 which he discharged the duties of Director of the Society of Anti- 

 quaries, was the youngest son of Sir Thomas Gage of Hengrave, in 

 Sufi'olk, the sixth Baronet of that ancient family. 



If this were a fit place from which to pronounce an eulogium on 

 private worth of the highest order, the memory of no one could de- 

 serve it better, and to his friends (and no one had more) the loss is 

 irreparable. But to the public also the loss is most considerable, 

 and to this more particularly it is my duty to refer. 



At an early period of his life he evinced an attachment to the 

 study of those antiquities for the knowledge of which he afterwards 

 became so eminent. I need but refer to the pages of the ' Archseo-
