Abstract
A FURTHER instalment of Dr. Raymond Pearl and M. R. Curtis's “Studies on the Physiology of Reproduction in the Domestic Fowl” appears in the Journal of Experimental Zoology, vol. xix., No. I. In this paper they deal with the distinction between “genetic” and “somatic” sterility. Some hens from high-laying strains, with the genetic characters for rich egg-production, were found to be sterile; the cause, when made evident by dissection, proved to be an oviduct with a mouth too narrow to afford entrance to the yolks, which, shed into the body-cavity, became absorbed through the peritoneum.
