Peryphus littoralis. Stenus pusillus. 



Notioijhilus biguttatus. Stenns laavis.

Several Planariae, and ova, or spawn, of various fishes and insects, were 

 procured from beneath the stones in the shallow channel of the river. 

 Viola hirta was found in full and luxuriant blossom, thereby adding 

 another to the already numerous localities of this species in Berwick- 

 shire ; which had been considered by Sir W. Hooker as of very rare 

 occurrence in Scotland. S}Tnj)hytum tuberosum was likewise observed 

 in considerable quantity, but not in flower. A rather singular twist, 

 resembling in shape the top of a saddle, was observed in the limestone 

 rock about a mile above Ninewells House, on the east side of the 

 river. Beneath a projecting slab of this rock, a considerable quantity 

 of acicular crystals of saltpetre was collected. — After dinner, Dr F. 

 Douglas read an account of the recent drying up of the river Teviot, 

 and explained, to the satisfaction of the party, the probable cause of 

 such a singular phenomenon. 



The Eev. Mr Wallace forwarded his annual summary of observations 

 of the barometer, thermometer, and hygrometer, made at the manse 

 of Abbey St Bathan's, in 1838. By this table it appeared that, not- 

 withstanding the unusual severity of the months of January and 

 February in that year, the mean temperatiu'e for the year only aver- 

 aged about 1^° F. lower than the previous year. 



Mr Selby read a very interesting paper on the effects which the 

 winter of 1838 had produced upon animal and vegetable life. Mr 

 Selby also read an account, and shewed a drawing, of a curious 

 aquatic Larva found in a water jug at Twizell. It was chiefly curious 

 on account of the unusual means which it employed to convey food to 

 its mouth. On each side of the mouth extends a number of bristles, 

 which diverge and open like a fan, and which appeared to be put in 

 motion by two small clickers at their base. In this manner the food 

 is brought to the mouth of the Larva. It unfortunately died previous 

 to undergoing a metamorphosis. 



On the 19th June the Club met at Coldingham. There were present 

 Rev. T. Knight, President ; Eev. T. Riddell ; Dr Johnston ; Eev. J. 

 Tixrnbull — who were joined by the Eev. Mr Tough ; Eev. Mr Eobert- 

 son ; Mr M'Laurin, jun., and the Eev. Andrew Thomson as visitors. 

 The latter gentleman was subsequently admitted a member on the 

 nomination of the Eev. Mr Tui-nbull, seconded by Dr Johnston.
