BODY WEIGHT TAIL LENGTH 161 



(100 Bd. Z.-l.l Bd. n+13400 



Body weight (male) = 10 1430 - 15 



Transpose 15 from right hand side to the left and take the 

 logarithm of both sides. We have 



(100 X 150 - 1.1 X 150) + 13400 

 log (Bd. wt. + 15) = log 10 X T

' 15000 -165 + 13400 



14300 



Thus 1.9745 is equivalent to the logarithm of body weight 

 plus 15. Therefore body weight + 15 = 94.3 (anti-logarithm 

 of 1.9745). Finally, body weight = 94.3 - 15 = 79.3 grams. 



The above procedure is that to be followed with other formulas 

 of the same type. 



BODY WEIGHT ON BRAIN WEIGHT (DONALDSON, '08)

Body weight (sexes combined) = 8.7+10 ^ (3) 



TAIL LENGTH ON BODY LENGTH. (HATAI, MS '14.) 



Tail length : male = 0.852 Bd. 1. + 38.8 (log Bd. I.) - 90 . 5 (4) 

 Tail length -.female = 0.874 Bd. I +43.2 (log Bd. 1) - 98.1 (5) 

 Formulas (4) and (5) were used for table 68.
