H. C. Lewis read a paper upon the results 
of his last two Aima geological work in Europe. Glacial action 
was essentially identical on both sides of the Atlantic. The ice- 
sheet which once covered the greater part of Ireland was com- 
posed of confluent glaciers, ie distinct ies glaciers occurred 
in non-glaciated areas. There seem to have been five centres of 
glaciation. No evidence of ree great marine submergence was 
discovered. Ice coming from Scotland across the North Channel 
seems to have joined the Irish sheet, and a mass of ice filled the 
Irish Sea, overriding the Isle of Man and Anglesea. Wales had 
fessor Lewis enunciated the principle that whenever marine shells 
occurred in glacial deposits at high levels it was not owing to 
submergence of the land, but to the advance of the ice out of 
the sea on to the land. He also believed that there had been but 
one advance of the ice. Probably the land had been elevated 
ve hundred feet, with a fall of temperature of about 10° 
Fahr. Professor Heilprin exhibited a series of fossil shells of the 
genus Fulgur, showing the derivation of the forms from each 
other. Miss L. E. Holman told of a new mode of multiplication 
of amcebe. A smaller one was a by a larger and after-

covery, in the Miocene beds of Tampa, Fla., of three pear ‘of 
Partula, a genus now confined to a small group of Polynesian 
islands. The probability of a former connection between the 
Atlantic and Pacific was spoken of. A fossil cowry from Florida 
was distinguished from all we probes forms by the presence of a 
sulcus from the mouth around the 
October 24.—Mr. Meehan ane some facts of local plant dis- 
tribution. In one case, under the shelter of a blackberry-bush 
in a cleared spot in a wood, twenty-two species not found in 
other parts of the wood had sprung up. Professor Ryder ex- 
hibited a curious fish, related to Gastrostomus, dredged by the 
“ Albatross” in fifteen hundred and nine fathoms. Professor 
Scott presented a paper on Mesonyx and Pachyzen 
November 2.—Professor Ryder spoke Asar deian the last ex- 
periments in oyster culture carried on by the United States gov-
