October 1st, 1874. After the summer recess, the first evening 

 meeting, being the sixth of the year, was occupied with a lecture 

 by Mr. W. Lant Carpenter, 15.Sc., *' On the Physical Theory of 

 Under- currents, and of Oceanic circulation generally, with some 

 account of H.M.S. Challenger ^ 



IS'oYember 3rd, 1874. At the seventh evening Meeting Dr. C. 

 Hudson gave a lecture on " Bristol Eotifers, their haunts and 

 habits." Some remarks on their classification were first made, 

 of which a report appears above, and then the lecturer passed on 

 to describe a few types, which were most eff'ectively shown by 

 large coloured diagrams illuminated as transparencies. Among 

 those exhibited in this way were Stephanoceros^ Floscularia, 

 (Elcistes, Linmias, Megalotrocha, Brachonus, and Rotifer viilgaris. 

 The difi'erent ponds and difeches round Bristol where these were 

 most likely to be found were added, and many useful hints given 

 about their capture. 



Mr. E. Tawney then read "iN'otes on Trias Dykes," while the 

 "Notes on the Eadstock Lias," and Mr. Stoddart's on *'The 

 Geological Distribution of Mosses in the Bristol District," were 

 taken as read. All appear above.

 W. W. Stoddart, F.G.S., read the second part of his paper on 

 the '' Geology of the Bristol Coal-field. — Silurian and Devonian." 

 It was illustrated by numerous large diagrams, and by a collection 

 of fossils from the beds referred to.
