should be about 0.12 per cent (Jackson '13). Since the body 

 weight has decreased about one-third (average 33.9 per cent) it 

 is evident that the eyeballs must have remained nearly sta- 

 tionary in absolute weight, thus increasing their relative (per- 

 centage) weight by about one-half. . In terms of absolute weight, 

 there would appear to be a reduction from 0.298 gram (the 

 theoretical weight corresponding to the initial body weight of 244 

 grams, according to Hatai '13) to 0.285 gram, the final average 

 weight of the eyeballs (table 3). This would indicate a loss of 

 4.4 per cent. 



A similar condition is found in the chronic inanition series. 

 The eyeballs here form an average of about 0.20 per cent of the 

 body weight, while the normal for the initial body weight aver- 

 ages about 0.13 per cent. (The higher figures in the chronic in- 

 anition series are due to the smaller initial body weight in this 

 series.) Thus it is evident that, with a loss of about one-third 

 (average 36.1 per cent) in the body weight during inanition, the 

 absolute weight of the eyeballs has changed but little. In terms 

 of absolute weight there would appear to be a reduction from 

 about ,0.280 gram (the theoretical weight corresponding to the 

 average initial body weight of 214 grams, according to Haiai 

 '13) to 0.2638 gram, the final average weight of the eyeballs 

 (tatle 3). This would correspond to a loss of 5.8 per cent in 

 the weight of the eyeballs during chronic inanition. 



That the eyeballs lose little or nothing in absolute weight 

 during inanition, increasing proportionately in relative (per- 

 centage) weight, is also indicated by the data of Falck ('54) 

 for the dog, and Sedlmair ('99) for the cat. Bitsch ('95) finds 

 the (absolute) weight of the eyeballs in the dog usually increased 

 during inanition, which he suggested may be due to oedema. 



THYROID GLAND 



The thyroid gland in the acute inanition series (table 3) forms 

 an average of 0.023 per cent of the body weight. The normal 

 for the initial body weights would average about 0.015 per cent 

 (Jackson '13). Since the body weight has been reduced one-third 

 during inanition, this would indicate that there has been no
