-p = + 0.173, p = + 0.842, 



L =+ 1.04 in., X / = +5.04in. 



On laying down these points on the pelvis and femur, I 

 found — 



Distance from 0 to centre of socket = 3.84 in. 

 Distance from 0' to centre of socket = 3.64 ,, 



Difference, 



The points O and 0 / are both inside the origin and inser- 

 tion. 



4. African Leopard — Adductor secundas — In this case 

 we have, 



2c = 2.05 in., 2^ = 6o° 30',

-^ = + 0.100, s( — ) = + 1.262 



corresponding to three fibres : from these data we find, as 

 before,

L = + 0.07 in., L' = + 1-03 in. 



On marking off the points 0 and 0' on the bones, I found —
