underfeeding experiments beginning on newborn albino rats, Stewart ('18) 

 found an increase of from 17 to 64 per cent in liver weight, but ('19) a loss of 

 23 per cent in rats held at birth weight by severe underfeeding for 16 days. 

 Barry ('20, '21) noted that the liver appeared 45 per cent subnormal in weight

Fig. 91. — Photograph of a section of the liver in an adult albino rat (No. O. 4) after 6 days of 

 inanition on water only with loss of about 25 per cent in body weight. Estimated loss of about 

 58 per cent in weight of the liver. Compare with Fig. 90, noting the capillary congestion and 

 the atrophy of the hepatic cell-cords, especially near the central veins. Nuclei poorly stained.
