Abstract : The main emphasis of the report is applied to the cochlea of the Chiroptera and Rodentia. Analysis of the many tape recordings made of the sounds emitted by these mammals has enabled the workers to postulate, and in some cases, verify theories of echolocation and voice production. This work naturally stimulates thought into the more pertinent problems of human auditory perception and voice production. New apparatus and techniques were developed to meet the specialised nature of these investigations. A reference collection is now available of both preserved specimens and serially saectioned slides - of many species of both the bats, rodents and other mammals. (Author)
