REPORT: OF THE CHEMIST. 125 
Under the head of nitrogenous or albuminoid matters in the above 
analyses there appeared to be at least four different kinds, viz: 
1. In Stowell’s Evergreen Sweet Corn part of the albumen is readily 
soluble in water, giving a clear solution, which is coagulated by acids. 
2. In the two other varieties of corn the albumen is insoluble in water 
both before and after treatment with ether and alcohol. 
2. The three samples of corn contain zein, an albuminoid, insoluble 
in water, but soluble in strong alcohol. 
4, Beans and pease contain a smali amount of an albuminoid, soluble 
in 95 per cent. alcohol and in water, and coagulated by acids. 
5. Beans and pease also contain about 25 per cent. of legumin, which 
is soluble in water, insoluble in alcohol, and coagulable by dilute acids. 
The composition of the ash in the above is as follows, excluding car- 
bonic acid:

In addition to the above, partial proximate analyses were made of the 
other samples of pease and beans, with the following results:

By reference to the above analyses, and those which have before been 
tabulated, it will appear that there are no greater differences than would 
necessarily arise from difference in the samples and the slight errors in 
analysis. 
Jt is well established that during the period of development the proxi- 
mate composition of the seed varies very widely; and should the light 
weight of the poorest thirds of the seeds analyzed be due to an imper-
