This Study, the fourth of a series on merino foetus, is concerned with the effect of age on (a) general body form, (b) body weight. (c) C.R. length, and (d) the relationship between the increase in weights and C.R. length. A comparison (e) is also made with the human foetuses. The changes observed are well illustrated in the Plates and five Charts. Previous Studies should be consulted for particular regarding material. In conclusion, we wish to record our indebtedness to Messrs. T. Meyer and G. C. Walker for their excellent work in regard to the Plates and Charts.
