The experiments to be described in this paper have been in progress in the Zoological Laboratory of Harvard University since the year 1900. They were begun for the study of conditions sex inthe higher animals, but have yielded results bearing on certain other questions, which alone will be considered in this paper. The animals used, guinea-pigs and rabbits, were selected because of their early maturity and fecundity. To provide them with food and shelter and to give them the necessary daily care, in addition to keeping records as full as possible, have been no small task. In this connection I am indebted for invaluable assistance to a number of persons. First of all to Prof. E. L. Mark, director of the zooloaical laboratory, without whose encouragement and support the experiments could never have been undertaken, and whd has more than once come to the rescue when the material resources at mv command were exhausted and further progress seemed impossible. The director and other officers of the Musel mo f Comparative Zoology, and the President of the University, have generously provided quarters for the animals and in other ways have aided the enterprise. Finally, when the increasing cost became a burden too heavy for the laboratory to bear, it was assumed by the Carnegie Institution of Washington in the form of a grant to Professor Mark and rnyself for experimental studies in heredity. Under the auspices of the Carnegie Institution the work has been in progress since January, 1904, and this paper is presented as a first detailed report upon it. In the course of the experiments about 3,000guinea-pigs and several hundred rabbits have been reared. For valuable guinea-pigs and excellent practical suggestions I aln indebted to lMiss Jeannette Soule, secretary of the National Cavy Club for an interesting stock of albino rabbits I am indebted to Prof. R.
