Abstract
THE hypothesis1 that antibodies are not transmitted through placentæ of the epitheliochorial and syndesmochorial types and are transmitted through hæmochorial and hæmoendothelial types was at one time widely accepted. More recently it has been demonstrated in the rabbit2 and guinea pig3 in which the placentæ are hæmochorial that the transmission of antibodies occurs exclusively via the yolk sac. In the rat transmission occurs by way of the yolk-sac endoderm and by way of the gut, and in this species some transmission across the hæmochorial placenta could not be excluded4.
