XIII. Contributions to the anatomy of fishes. II. The air-bladder and Weberian ossicles in the siluroid fishes

Abstract

An abstract of the first part of this memoir, which dealt with the structure and relations of the air-bladder and Weber’s ossicles in the Siluridæ, was published in the Proceedings of this Society three years ago (‘Roy. Soc. Proc.,' vol. 46, 1889, pp. 309—328). The present contribution is a discussion of the physiology not only of this remarkable mechanism, but of the air-bladder in general.
