Abstract
Routine consecutive autopsies were made on 216 Macaca mulatta. The effects of sex, wt. and health on the wts. of brain, endocrines and visceral organs of 118 of these are presented and analysed, with particular attention to a group of 103 immature animals weighing between 1,000 and 4,500 g. The wt. of the brain alone is influenced by the sex of the animal. The mean brain wt. of the [male][male] in this group being 85.7, and that of the [female][female] 76.5 g. Increasing body wt. with age is accompanied by a concomitant increase in absolute organ wt.; the relative increase is different for the different organs, the small endocrines increasing less than the larger structures. The glandular tissue is less, the fatty tissue of the thymus more in the heavier (older) animals. Poor health, as indicated by loss of wt. in a group of 52 animals without serious gross disease, affects various organs in different ways. The chief loss of wt. occurs in structures other than the endocrines, or visceral organs, chiefly in the fatty tissues. Loss of body wt. is accompanied by marked loss of glandular and fatty tissue from the thymus; there is loss of wt. in spleen and pancreas, and to a less degree in testicles and ovaries. The wt. of the remaining organs is little affected.
