Regarding to the origin of the domestic cattle in East Asia, the author studied the cranial bones of foetus and found that the results obtained were in a fair agreement with those from his previous research with respect to the cranial construction of adult cattle.
The conclusion of the present paper is as follows:
1. The cranial bone of foetus of the Corean cattle were found to present those of Bos taurus and somewhat to be defferent from the materials employed by Duerst and Wilckens. They were proved to be rather resemble those of the Mongorian cattle foetus.
2. The cranial bone of cattle foetus of North China were found to be quite similar in their construction to those of Bos zebu indicus.
3. The cranium of the Manchurian cattle foetus resembles very much that of the Corean cattle foetus, but there was found also a resemblance between the former and that of the Mongorian. From this facts it may be said that the Mongorian cattle have characters of Bos zebu indicus.
4. The cranium of the Mongorian cattle foetus showed an intermediate form between Bos taurus and Bos zebu indicus, representing that of the Carolaise cattle foetus reported by Duerst.
