(That fat is a real formation, dependent for its composition on the work of living tissues, is clear from the well-known fact that the fat of one animal differs from that of another, and that it preserves its identity, no matter what the food may be, or in what form fat itself may be provided. Certain constituents of the animal's fat may be wholly absent from the fat of its food, yet they appear just the same in the fat produced under such diet. Even bees can construct their wax from proteid, or use unlike substances, as sealing-wax. But histological examination of forming adipose tissue itself throws much light upon t} jject Fat-«ells are those in which the protoplasm has buuu largely replaced by fat. The latter is seen to arise in the former as very smedl glohules. vUl \* Ite. 184.—KMiuBMr rUimI of huniMi femftto (ptter li6gMlm\ 1, rinflK, or dilatation of one at lac
