cannon bone size

[Jack_Weaver@cc.chiron.com]

     I think I remember a study of cannon bone length and diameter in 
     endurance (Tevis?) horses.  Can anyone tell me where I can find it?  I 
     looked around the Tevis home page and some in the ridecamp archives 
     without success.  I'm looking at a new prospect with what I would call 
     medium size legs and would like to see how he compares to some 
     successful endurance horses.
     
     Thanks for any help
