 portion. Just so with the cow. She produces nothing, she only 

 transforms. If she transforms into ilesh an unduly large amount 

 of feed consumed she not only has almost wasted the amount 

 of feed required to produce this extra weight, but is also handi-

 cavity for large lungs for the purifying of a large quantity of 

 blood and for a large, strong heart for the pumping of this

 Some thin, deep-chested horses are able to work, run or fight 

 the larger, heavier horses literally to the grave. Another item
