Weights of Brains and Organs of 132 New and Old World Monkeys¹

THE MATERIAL here presented has been derived from the autopsy records of 132 monkeys of various New and Old World species, and has been compiled to-gether with similar material on 246 Macaca mulatta and 70 anthropoid apes published in conjunction with the present paper. The literature concerning such data has been discussed in the paper on Macaca mulatta. There, also, in the larger series of complete autopsies, evaluation of the statistical data has been made.All autopsyprocedure and compilation of figures has been done in the same way in all three groups,—the grouping into anthropoids, Macaca mulatta and “other monkeys” was made largely for convenience. In all papers the animals are those used in the Laboratory of Physiology, Yale School ofMedicine, during the past 10 years.
