 Constants of Hyperboloid. 

 2C = 2.05 



2<j> = 6o° 30' 



The points / and I' were found by combining the fibres in 

 pairs, the mean result giving the following relation between 

 a and a' : — 



13.56 a' = 10.90 a - 16.31 



a' = 0.804 - I.203. 



From which I obtained, as before, 



0.84 a 2 - 0.73 a - 0.20 = o 



( - 0.22 ( - I.38 



Taking the first pair of values, as before, I find — 



African Leopard — Adductor secundus ()3). 

 a = + 1.09 in. a 1 = - 0.34 in. 



cti = - 0.29 „ a\ = + 2.36 „ 



a 2 = - 1.67 „ a' 2 = + 5.06 „
