[The chondrocranium in sheep and goat. I. (author's transl)].

The morphogenesis of primordial cranium was studied in 12 merino-sheep fetuses (between 25th and 67th day of development) and in 10 goat fetuses (between 24th and 52nd day of development). On the base of histological sections a reconstructional model of the nasal capsule was made.from a 67-day old sheep fetus. In the work, the stages of chondrocranial development in both the two small ruminats were indicated, and the main differences in the construction of chondrocranium in sheep and goat, are like wise shown.
