abundance, and vary in size from half an inch to several 

 inches in length. Mr. Travers believed that, notwith- 

 standing their artificial aspect, they were formed merely by 

 the cutting action ot wind-driven sand, as it drifted over an 

 exposed boulder bank which forms the higher part of the 

 isthmus. Dr. Hector, while adopting this view, had re- 

 marked that if they had been elsewhere associated with 

 works of human art, they would have been referred to the 

 so-called stone period. 1 Dr. Hector thought that the Umus 

 of the Maoris (the kjokkenmoddings of New Zealand) were 

 places likely to favour the production of these stones, being 

 generally on rising ground among sand dunes. Sir P. 

 Egerton said that Lord Selkirk had given him a stone, 

 polished by driving sand, which he had found in Egypt nine 

 years ago. This he would bring to the Club (see next page). 

 Mr. Evans felt some doubt about the origin assigned to 

 these stones, but reserved his opinion till he had an oppor- 

 tunity of examining them. 



May 27th, 2O2nd meeting. Mr. Sclater said that a few 

 days previously a living specimen of the rare mammal 

 Ailurusfulgens, the correct zoological position of which is still 

 doubtful, 2 had arrived at the Zoological Gardens. It had 

 been obtained near Darjeeling, and brought to England by 

 Dr. Simpson. 



June lyth, 2O3rd meeting. Mr. Prestwich referred to the 

 subway then being constructed under the Thames, which 

 was expected to be finished in about two months. The 

 tunnel was about 9 feet in diameter, and some 20 feet below 

 the bed of the river, being cut entirely through the London 

 clay, at the rate of about 9 feet a day. 



1 They are described and figured by Mr. J. D. Enys in Quart. Jour. 

 Geol. Soc. vol. xxxiv. (1878), page 86. Specimens have been placed by 

 myself in the Sedgwick Museum, Cambridge, with sand-worn stones 

 from near Wady Haifa, Egypt, given to me by Colonel H. G. Lyons, 

 F.R.S. These dreikanter, etc., have been often noticed in recent geological 

 literature. 



- Aelurus fulgens, the panda, is placed by the late W. T. Blanford, The 

 Fauna of British India (Mammalia), page 189, in the Procyonidae (racoons, 

 etc.). The genus contains but a single species peculiar to the Himalayan 

 region.
