It is plain that there has been a very marked falling off in albumi- 

 noids. Twenty-eight of the fifty-seven varieties examined this year 

 were also among the specimens ot 1881. The averages for the two 

 years of the same varieties show in the same way changes such as were 

 seen in the average of all.

There has been a falling off in ash and albuminoids, and in the weight 

 of 100 grains, and the uniformity of the change in these respects is 

 shown by a comparison of each analysis in this regard.
