Attention has been frequently directed to the prenatal development of various animals, as well as of man. This embryonic development of the bovine foetus is to be the subject of special investigation by the Agricultural College of the University of Missouri, and this analysis of a new born calf is intended as one of a series of contributions on that point. Most analyses of this nature have been confined to the mineral constituents, at least parallel work is not available here. In fact, very little similar work of any kind has been done on domestic animals. Still a comparison of work similar in any respect is interesting and may be of value, although the composition of a new born calf, or of a calf embryo, may be slightly different from that of any other species.
