Abstract
MANCHESTER
Scientific Students' Association, Oct. 20.— Mr. John Plant, F.G.S., in the chair.—Mr. Wm. Gee lectured on Polytrichum commune (the common Hair-moss), as a type of mossstructure, commenting on the points of differentiation between true mosses and cryptogams erroneously associated with them, tracing the life-cycle, the minute anatomy of the organs, and the function of mosses in nature and art.—The Chairman exhibited a collection of Ammonites from the Kimmeridge Clay and from the Tertiary Sand near Alexandria.—Mr. C. Robinson showed local drift-shells; and Mr. Gee a miner's lamp-glass, tempered by the new process to withstand change of temperature, although of the usual thickness (¼ inch).
