 The second fact of importance was that a wheat-grain and corn-stover 

 ration was not perfectly complete, giving at times weak ofifspring and 

 also indicating that the wheat grain was a contributor to the failure of 

 a wheat-grain and wheat-straw ration. In addition to Table II, there 

 are added a number of illustrations (PI. 23, 24, 25, A-B) showing the con- 

 dition of the mothers and the calves at date of birth. 



Attention should be called to the peculiar limpness and weakness of

 individuals would be able to get up after birth, nurse, and take care of 

 themselves; but more often they would lie stretched out limp and 

 unable to hold their heads in an upright position and would have died
