There was a loss of albuminoids in every variety, with four exceptions, 

 and a decrease in weight in all but one. This change, which at first 

 seemed rather surprising, is explained by Professor Blonnt in the fol- 

 lowing letter: 



Colorado Agricultural College, 



Fort Collins, Colo., June 17, 1884. 

 My Dear Sir : Yonr letter of the 11th, inclosing analyses of wheats, received. I 

 am not at all surprised at the falling off in the albuminoids and other deleterious 

 changes. I think I can give a satisfactory reason for the deterioration.
