following year published an account of his ' Travels ' in that country. 

 In 1813 he removed to London and commenced the publication of a 

 scientific periodical under the title of the ' Annals of Philosophy ; ' 

 but having been appointed Lecturer on Chemistry in the University 

 of Glasgow in the year 1817, and this office being converted in the 

 next year into a Regius Professorship, he found it necessary to quit 

 London, and after a time to resign the editorship to his friend Mr. 

 Richard Phillips, from whose hands it subsequently passed into those 

 of Mr. Richard Taylor and is now incorporated with the ' Philosophical 

 Magazine.' He married in 1816 Miss Agnes Colquhoun, daughter 

 of a distiller near Stirling ; and has left a son (also a valued Fellow 

 of our Society) and a daughter married to her cousin Dr. Robert 

 Dundas Thomson, who for the last twelve years assisted his uncle 

 in the duties of his chair. Dr. Thomson was elected a Fellow of 

 the Royal Society in 1811 and of the Linnean Society in 1812 ; and 

 died at Kilmun, in the county of Argyle, on the 2nd of July last, in 

 the 80th year of his age. It would be out of place in this Society 

 to enter into any detail of his numerous and valuable contributions 

 to the science of chemistry, which he enriched not only by the pro- 

 duction of a series of standard works, remarkable for the amount of 

 conscientious labour which they involved, but also by many im- 

 portant discoveries and inventions whicii were entirely his own. But 

 it is right to mention, as more particularly connected with natural 

 history, his 'Outlines of Mineralogy, Geology, and Mineral Analysis,' 

 published in 1836 ; with a view to which he had formed a fine 

 mineralogical collection, which remains as a substantial monument 

 of his taste and of his devotion to science. 



Frederick Thomas Wintle, M.D., was for six-and-twenty years re- 

 sident Physician to the Warneford Asylum for poor lunatics, in the 

 neighbourhood of Oxford. His constant ill-health prevented his 

 appearing much before the world as a man of science ; but he con- 

 tributed to the ' Lancet ' several memoirs on subjects connected 

 with his profession. He became a Fellow of the Linnean Society 

 in 1831 ; and died at the age of 50, on the 14th of February in the 

 present year, at Cheltenham, whither he had gone for change of 

 air and relaxation from the cares of his office. 



In our Foreign List we have to lament the loss of 

 The Baron Leopold von Buch, Chamberlain of the King of Prussia, 

 and one of the most distinguished geologists of the age, who was a 

 native of Prussia and born on the 25th of April 1773. He received his
