Chart showing the curve of growth of the test male rats refed after maintenance trom three to ten weeks of age, superimposed upon that of the control males, so that the starting points coincide. The curves are drawn through points representing the aveiages of the individual weights of the rats of litters S8, Sg and 814, at the various periods. Body weight in grams is represented on the ordinate and age in days on the abscissa. Controls. Rats refed after seven weeks of maintenance. during inanition the cell nucleus becomes relatively large, the loss of substance being greater in the cytoplasm. Thus inanition tends to reduce the body cells to an embryonic condition, as found by Child ('15) in extensive experiments upon Planarians. It is also possible that the accelerated growth following periods.
