Ablation of the gluteal muscles in rats, three weeks old, has been shown to result in an average diminution of 7 % in the other blocks of hip muscles. Concurrently, the weight of the innominate bone is reduced by 7 % and its dimensions by an amount varying between 1 % and 8 % and averaging about 3 %. This reduction in size and weight is comparable with that obtaining in the rat skull following bilateral masseterectomy. The dimensions of the innominate bone most affected by the reduction in muscular pull are those of the iliac blade, whose proportions, however, remain unaltered–a finding indicative of an appreciable measure of genetic control of this feature.
