.Robert Marcus Gunx, M.A., M.B., F.R.C.S. (1851-1909).— 



Mr. Gunn was an eminent oculist who, while busily engaged in his 

 profession, found time for much original investigation ; he published 

 many scientific papers on the comparative anatomy of the eye and 

 on the physiology of vision, he also pointed out the . importance of 

 visible changes in the blood-vessels of the retina as indicating 

 alterations of even graver significance in the general system. In 

 his holidays he devoted himself enthusiastically to natural history 

 and geology ; he made a large collection of fossils from the Jurassic 

 rocks of Sutherland — his native county — and from the Old Red 

 Sandstone of Caithness. He was the discoverer of the famous 

 Palceospondylus c/unni. Up to the time of his death he was 

 collaborating with Prof. Seward in a memoir on the Jm*assic Flora 

 of Brora, based mainly on his own collection, which has now been 

 placed in the British Museum (Natural History). He was elected 

 a Fellow of this Society in 1908. 



He died at Hindhead on December 2nd, 1909. 



Hindericus Martinus Klaassen (1828-1910). — Mr. Klaassen 

 was born at Kritzura (Hanover) in 1828. In 1874, on retiring 

 from business in London, he entered University College, London, as 

 a student of Natural Science, paying particular attention to Geology. 

 He became a member of the Geologists' Association in 1875, and in 

 1883 communicated a paper to it ' On a Section of the Lower 

 London Tertiaries at Park-hill, Croydon ' (Proc. Geol. Assoc, vol. viii, 

 pp. 226-248). This is a valuable record of observations made 

 during the excavation of a railway-cutting through the hill. This 

 cutting also yielded to Mr. Klaassen the remains of some new 

 species of fossils, the most interesting of which are Corypliodon 

 croydonensis and Gastroruis 7daasseni, both described by Mr. E. T. 

 Newton, F.R.S. 



Mr. Klaassen was elected a Fellow of the Society in 1877. He 

 died on January 22nd, 1910. 



William Fokd Stanley, J.P. (1828-1909).— Mr. Stanley was 

 born at Bunting-ford (Hertfordshire) in 1828. At an early age he 

 was apprenticed to his father, a well-known mechanical engineer, 

 and in 1854 he began business on his own account. As an inventor, 

 designer, and manufacturer of scientific instruments he met with 

 remarkable success. He was the author of several books, some 

 speculative, such as 'The Nebular Theory in relation to Stellar, 

 Solar, Planetary, Cometary, & Geological Phenomena,' and one —
