Theseconditiqns are shown in diagram III. The replacement of body substances by water in the different partsof the body, and the almost complete destruction of fat, demonstrates ^* For this determination 25 grams of lean muscle from corresponding partsof the leg were selected, weighed and dried. The quantity of air-dried musclewas determined, then the dried material was powdered and the water content ofthis powder determined. NUTRITION AND GROWTH: I. 33 that all the animals on low diet were in a stage of starvation. Indeed^while their body weights remained constant, or were increased slightly,the animals were losing body substance, so that, while 1 gram of liveweight of dog VI represented only 0.55 calories, the same weight of dog Vrepresented 1.42 calories. This latter value agrees well with Rnbnersfindings (1 gram of dog equals 1.50 calories). Nearly two-thirds of theenergy which dog number VI had stored at the time the experiment beganmust have been consumed during the experiment.

Diagram 3.- Ash Protein ral -Composition ot bones of dogs V and VI of Experiment II. It is quite interesting to compare the composition of the dogs whichwere kept on a low diet and the body weights of which remained con-stant or even increased slightly with that of adult animals which haveundergone starvation. During starvation of adult animals all parts of the body, even theskeleton, lose in mass. Skin, hair, and organs lose more than the muscles,but in our young dogs the muscles lose considerably more than theorgans, which suffer scarcely any loss. Muscles, organs, brain, and spinalcord of a starved adult dog have the same water content as they havewith normal dogs; the blood even becomes somewhat richer in solids.The converse is true with our dogs for there is a large decrease of solids,which is the most pronounced in the blood. However, in one respect thephenomenon is the same for starved young and for adult dogs, that is,the loss of fat from the muscles is comparatively greater t
