Rh 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 remarkable fact noticed in this memoir, is the presence of silex in a few specimens. Dr. Yelloly finds reason to believe that the average number of calculous disorders occurring in Scotland has been much underrated ; that, on the other hand, the proneness to these complaints is very small 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 deplore 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-
