ALIMENTARY TRACT OVARIES 167 



Weight of Alimentary Tract on Body Weight (Hatai, '13) 



Weight of alimentary tract (sexes combined) = 



. 0245 Bd. wt. + 4.720 log (Bd. wt. + 7) - 5.753 (21) 



Formula (21) was used for table 70. 



Weight of Both Testes on Body Weight (Hatai, *13) 

 Wt.of testes = 0.022 -0.00992 Bd. wt. + 0.00127 Bd. wt.* (22) 



[4 <Bd.wt.< 10] 

 = 0.043 - 0.000966 Bd. wt. + 0.000163 Bd. wt. 2 (23) 

 [10 <Bd.wt.< SO] 



= 2.910 log Bd. wt. - 4.520 (24) 



[Bd. wt. > 80] 



For the weight of the testes for body weights of 4-10 grams, 

 the values were obtained by formula (22), while formulas (23) 

 and (24) were used for obtaining the values for body weights of 

 10 grams or over. Formulas (22) (23) and (24) were used for 

 table 70. 



Weight of Both Ovaries on Body Weight (Hatai, '13) 



Weight of both ovaries = 



= 0.00781 log. Bd. wt. - 0.0047 (25) 



(Phase 1) [Bd. wt. < 65] 



= 0.0425 - . 00121 Bd. wt. + 0.0000108 Bd. wt. 2 (26) 

 (Phase 2) [65 < Bd. wt. < 1 10] 



= 0.007 log. (Bd. wt. - 105) + 0.0352 (27) 



(PhaseS) [Bd. wt. > 110] 



Formulas (25) (26) (27) were used for table 70.
