LIVER WEIGHT BLOOD VOLUME 165 



WEIGHT OF LIVER ON BODY WEIGHT (HATAI, '13) 



Weight of liver (sexes combined} = 



0.0303 (Bd. wt. + 5) + 3.340 log (Bd. wt. + 5) - 3.896 (16) 

 [Bd. wt. > 10] 



Formula (16) was used for obtaining the values given in table 69 

 for body weights of 10 grams or above. For body weights below 

 10 grams the weights have been determined by graphic inter- 

 polation using the crude records as a basis. 



WEIGHT OF SPLEEN ON BODY WEIGHT (HATAI, '13) 



Weight of spleen (sexes combined) = 



. 00245 Bd. wt. + Q. 0301 log (Bd. wt.) - 0.025 (17) 



Formula (17) was used for table 69. 



WEIGHT OF BOTH LUNGS ON BODY WEIGHT (HATAI, '13) 



Weight of both lungs (sexes combined) = 



0.00471 (Bd. wt. + 2) + . 122 log (Bd. wt. + 2) - . 056 (18) 



Formula (18) was used for table 70. 



VOLUME OF THE BLOOD ON BODY WEIGHT (CHISOLM, '11) AND HATAI (MS '14) 



Bd wt - 9 



Blood volume (sexes combined) = '- '- = . 099 Bd. wt. - 9 (19) 



10.1 



[5 < Bd. wt. < 150] 



Blood volume (males') = 



0.099 Bd. wt. - 9 - .03 (.099 Bd. wt.) - 9 (19a) 



= 0.09603 Bd. wt. - 9 

 [150 < Bd. wt. < 350]
