142 PROCEEDINGS OF SOCIETIES. 



Harker, Esq., F.R.M.S., was elected in 1857 and died November 16tli, 

 1871. Of the death of Mr. Wilkinson the Secretaries failed to obtain 

 any accurate record : he was elected in 1863. Sir Eoderick Murchison, 

 Bart., F.R.S., &c., became a Fellow of the Society in 1816, but 

 it does not ajipear that his attention was at any time directed to 

 microscopical research. He was, however, highly distinguished by 

 his various contributions to geological science, and in particular 

 by his great work, ' Siluria,' in which he treated of the whole of 

 the deposits of the Silurian strata from his own close observation in 

 all parts of Europe. This work, the last edition of which appeared 

 in 1867, includes the materials of the Silurian system, with such 

 additions and corrections as were needed to the above-named date, 

 and is a monument of geological research. One of the points which 

 has been settled from Sir Roderick's observations is the position of 

 the rocks of the north-west coast of Scotland, which had been sup- 

 posed to be old red sandstone, but were at length foimd to underlie 

 rocks containing Silurian fossils, and therefore to be classed as 

 Cambrian. These rocks were, in fact, found to be the oldest Cambrian, 

 lying below the fossil-bearing Cambrians of the Welsh coast and of 

 the east of Ireland, which were esteemed the lowest fossiliferous rocks 

 until the discovery of organic remains in the Laurentian rocks of 

 Canada, in the valley of the St. Lawrence. 



Sir Roderick, having acted for five years as secretary of the 

 Geological Society, became president of that body in 1831-2, and 

 again in 1842-3. He was one of the founders and most active 

 members of the British Association for the Advancement of Science ; 

 for several years he acted as general secretary, and presided over its 

 meeting at Southampton in 1846. He has from year to year taken 

 the leading part in the business of the Geographical Section, and has 

 communicated many important papers. In 1844 he was elected 

 president of the Royal Geograj^hical Society, was re-elected in the 

 following year, and again in 1852 and in 1856.
