Abstract
LONDON Royal Microscopical Society, October 9.—H. J. Slack, president, in the chair.—This was the first meeting of the present session. Numerous presents were announced and acknowledged, and Major Festing and John Borland were elected Fellows of the Society.—The president called attention to a specimen of the perforating proboscis of a moth which had been received from Colombo, and compared its structure with that of a species which had been the subject of discussion at a former meeting.—An interesting paper was read by Prof. Owen upon certain fossils found in the middle Purbeck, to which he had given the name of Granicones, and which, after careful comparative examination, he had decided to be the dermal scutes of a lacertian closely resembling the now existent Australian species, Moloch destructor. He pointed out that the remains found in these rocks were chiefly those of marsupials, and that in the rnesozoic strata both animals, plants, and shells had now their only living representatives at the antipodes.—Communications were read from Col. Woodward on the modification of the illuminator for balsam-mounted objects, also from the American Microscopical Congress recommending the adoption of the 1/100 millimetre as the standard for microscopical measurements.—A discussion ensued, in the course of which it was suggested that much advantage would arise to microscopists from the more careful adherence on the part of makers to the Society's standard screw, and also greater uniformity as to size of tube, eye-pieces, and other mechanical details.
