Forty-two embryos and fetuses of Frisian cattle, distributed onto 14 groups on the basis of crown-rump lengths between 1.3 cm (about 23 days) and 9.5 cm (70 days), were to study the morphogenesis of the bovine stomach. The work is divided into three parts. Part 1 deals with the ruminoreticulum and parts II and III the omasum and abomasum.
