LONDON. Linnean Society, March 2.—Dr. A. Günther, F.R.S., President in the chair.—Mr. H. M. Bernard showed some microscopic sections of the digestive cæca of spiders, which had led him to the conclusion that digestive, assimilatory, and excretory functions are all performed by these.—Mr. J. E. Harting exhibited a male specimen of the rare King Eider (Somateria spectabilis) which had recently been forwarded in the flesh from Lerwick, and called attention to the colours of the soft parts, which differed materially from the colours represented by Gould in his folio plate of this species.
