Abstract
THE method elaborated by Manoilov for distinguishing the sexes has been used by us in the case of the fowl. Male can certainly be distinguished from female by this test. Seven birds which previously functioned as hens but now, having undergone complete sex-reversal, are fecund and potent cocks, all exhibit the female reaction indubitably. This being so, this test may be expected to provide valuable corroborative evidence concerning the genetic sex of certain kinds of sexually abnormal individuals.
