Within recent years it has been l earned that the growth and development of the organs of the albino rat can be expressed in terms of human development; that is, certain ages of days or months in the rat are comparable to ages of months and years in the human being. With this discovery the albino rat has become the subject of a widespread and thorough investigation and has grown in popularity and in value as a laboratory animal. Donaldson (3), Drake and Heron ( 4). allthough there are several articles giving the effect of abnormal conditions, Cummins (2) and Gould (5), in the internal ear, we have been able to find only one article on the normal development of the cochlea and cochlearis in the albino rat, Wada (14) , which deals with the development of the cochlearis after birth . Believing that there is need for investigation on the fetal development of the cochlea and cochlearis in the albino rat , this problem is presented.
