Abstract
LONDON. Royal Microscopical Society, October 17.—Mr. Heron-Allen, president, in the chair.—H. Sidebottom: Recent Foraminifera dredged by H.M.S. Dart off the east coast of Australia in 465 fathoms. The locality lies off the coast of New South Wales, about 250 miles north of Sydney, and more than fifty miles from the coast-line. In this area the coast slopes rapidly down to Thomson Basin, an isolated deep (maximum 3000 fathoms) area between 24° and 52° S. and 149° and 165° E. Pteropods are found only in tropical and subtropical areas, and are of extremely limited occur rence in the Pacific. A great number of specimens are recorded, but few of more than local interest, the principal feature being a streat variety of certain modi fications of the genus Discorbina.—F. M. Duncan: Mounting and preserving marine biological specimens. The author described the methods adopted and standard ised by him tor the microscopical investigation of marine Algae, Protozoa, general Plankton, Hydromedusae, Ecninodermata, larval and adult Crustaceans, Ascidians, etc. The importance of standard percentage solutions of formaldehyde, value of mentnol as a general narcotic, advantages of turpineol as a clearing media for Crustacea, and the disadvantages of fixing with chromic acid or bichromic salts were also fully discussed.
