Weight of the Submaxillaries on Body Weight (Hatai, '18) 



Weight of submaxillaries (2) {Males and females) 

 = 0.00152 {Bd. wt. + 5) + 0.0542 log {Bd. wt. + 5) - 0.0524 



Bd. wt. ^ 5 (26) 



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



Wt. of testes = 0.022 - 0.00992 Bd. wt. + 0.00127 Bd. wt.^ (27) 



[4 < Bd. wt. < 10] 

 = 0.043 - 0.000966 Bd. wt. + 0.000163 Bd. wt.^ (28) 



[10 < Bd. wt. < 80] 

 = 2.910 log Bd. wt. - 4.520 (29) 



[Bd. wt. > 80] 



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

 the values were obtained by formula (27), while formulas (28) 

 and (29) were used for obtaining the values for body weights of 

 10 grams or over. Formulas (27) (28) and (29) were used for 

 table 146. 



Weight of Both Epididymides^on Body Weight (Hatai, '18) 



Owing to the presence of two distinct phases of growth two 

 formulas were used. Formula (30) for body weights up to 

 100 grams and formula (31) for body weights above this. 

 Table 147. 



Weight of epididymis {2) 



0.003 + 0.00024 Bd. wt. + 0.00002 Bd. wt.-" 



Bd. wt. < 100 (30) 



1.65 log Bd. wt. - 0.000762 Bd. ivt. - 2.9945 '
