study in its University, graduated tliere in 1796. Four years after- 

 wards, he settled in London, and became a Licentiate of the College 

 of Physicians. In 1806, he married Miss Tyssen, heiress to a con- 

 siderable landed estate ; and established himself in Finsbury Square. 

 About this time, also, he was elected Physician to the Aldersgate- 

 street Dispensary ; and, in 1817, succeeded Dr. Cooke as Physician 

 to the London Hospital. He became a Fellow of this Society in 

 1814. 



Endowed by nature with great activity of mind. Dr. Yelloly ap- 

 plied himself with indefatigable industry to the acquisition and the 

 extension of medical knowledge. His views were not confined to the 

 narrow circle of his own individual advancement, but, embracing a 

 wider range of utility, they extended not only to the improvement, 

 but also to the general diffusion of science, and to whatever was cal- 

 culated to raise the character and exalt the dignity of the profession 

 to which he belonged. This liberal public spirit, indeed, was, 

 throughout life, the main spring of his exertions ; and one of its prin- 

 cipal fruits was the formation, in conjunction with his friend Dr. 

 Marcet, of the Medical and Chirurgical Society of London. The 

 objects contemplated by such an institution were to establish a closer 

 bond of union than had previously existed among the several branches 

 of the medical profession ; to collect a comprehensive medical library 

 for their use ; to read and discuss medical papers at the evening 

 meetings ; to publish a selection of these papers in the form of Trans- 

 actions ; to promote a free interchange of information, and to culti- 

 vate liberal and kindly feelings among the members. Many of the 

 most eminent practitioners, both in Medicine and Surgery, were in- 

 vited to join this new Society, which, from small beginnings, soon 

 increased in numbers and in reputation, so as in the course of a few 

 years to comprise a large portion of the professional rank and talent 

 of the metropolis. It was to the active exertions and persevering 

 zeal of its two founders that this Society was mainly indebted for its 

 early success and its continued prosperity, amidst occasional difficul- 

 ties with which it had to contend. Dr. Yelloly, in particular, de- 

 voted himself to its welfare with the attachment of a parent. At its 

 commencement he officiated as Secretary, in conjunction v/ith Mr. 

 Charles Aikin ; and for many years he was scarcely ever absent from 

 its meetings, taking a lively interest in all its proceedings, and an 

 active part in the discussions of the evening. To its Transactions 

 he contributed many valuable memoirs'^. At a later period, about
