XV. On the urinary organs and secretions of some of the amphibia. By John Davy, M. D. F. R. S. Communicated by the Society for the Improvement of Animal Chemistry

Abstract

T he urinary organs of the amphibia have been imperfectly described by authors; but I am not aware that any account has hitherto been published of the urinary secretion of any of this class of animals. Since I have been in Ceylon, both subjects have excited my attention, and on both I have had favourable opportunities of gratifying my curiosity. It may not be uninteresting to the Society, to know the results of my observations. I shall briefly state them, confined as they are at present to a few animals of four natural families.
