BODY WEIGHT TAIL LENGTH 161 



(100 Bd. l.-l.l Bd. I.) +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. wtf.+15) =log 10X- 



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 f ormulas- 

 of the same type. 



BODY WEIGHT ON BRAIN WEIGHT (DONALDSON, '08) 



Br. wt. -0.554 



Body weight (sexes combined) = 8.7+ 10 569 (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. 1. +43.2 (log Bd. I) - 98. 1 (5) 

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