Proceedings of the Royal Society for November, 1867

The monthly evening meeting of the Fellows was held on Tuesday, the 12th. November, J, Barnard, Esq., in the chair.
Captain W. Crosby, who had been previously nominated by the Council, was after a ballot declared to be duly elected a Fellow of the Society.
Mr. M. Allport brought for exhibition some living miscroscopic objects either identical with or closely allied to Volvox globator. Before placing them under the instrument, Mr. Allport remarked that his attention was first drawn to these specimens from the fact, that out of several small fish ponds one only contained the volvox, and in that pond the perch fry invariably grew more rapidly than in any of the others, leading to one of two conclusions—either that the minute fish feed upon the volvocines which are distributed through the water in countless myriads, or the volvocines supply food to a number of small insects or crustaceans, which in their turn go to feed the fish.
