It is evident then that the formation of creatin in muscle is inde¬ pendent of the growth of that tissue.

The development of body weight, liver and creatin in chickens during incubation. -and O indicate body weight. -and □ indicate creatin. -and X indicate liver. Abscissae represent periods of incubation in days. Ordinates represent weights of liver, body and creatin respectively. Outside figures weights of liver in grams. Middle figures weights of body in grams. Inside figures weights of creatin in milligrams. 1 The increase of weight from 30*5 to 36 grams in the 20th day does not mean that the muscle weight has so increased. It is remarkable how quickly at hatching chickens receive a complete coating of egg-substance under their skins and consequently it is impos¬ sible to get the correct weight at this time. Even this apparent increase in weight, however, is not comparable to the increase in creatin.
