3 Pleft S. 425, the composition of beets grown with the application 
°t Phosphoric acid, nitrogen (as nitrate and ammonia salts) and 
soda. The results vary so little for the different sets of beets that 
we may consider them as within the limits of the natural variability 
of the plant itself. The soil experimented with was not so rich in 
ime, magnesia, potash, phosphoric acid or nitrogen as we find our 
sons to be. The general composition of the eleven samples analyzed 
is : average weight of beets, 253 to 384 grams. Sugar 17.2 to 10.2 
aveiage 18.2. Dry substance 24.68 to 26.54, average 25.61. Ash, 
apparently carbonated ash, in dry substance 2.19 to 2.55, average 
2.39. Ash in beet (carbonated?) 0.61208. Total nitrogen in dry 
substance 0.80 to 1.29, average 0.95364, in beet 0.2445. Phosphoric 
acid m dry substance, 0.28 to 0.38, average 0.3082, in beet 0.07893. 
Potash m dry substance 0.58 to 0.84, average 0.7155, in beet 0.1833. 
Owing to the fact that soda ih the form of sodic chlorid was applied 
as a feitilizei, and that sodic salts constitute a considerable percent¬ 
age of our alkalis, the results obtained in regard to the effects of 
soda have an especial interest for us. The soda in the dry sub¬ 
stance of these beets was from 0.18 to 0.48 percent, the average 
0.2496, in the beets 0.06541. We quote the analyses of the pure 
ash m full, omitting the details of the experiments.

Number s 1 and 11 received no fertilizers of any sort. The 
authors failed to discover any relation between the amount of sodic 
oxid and the sugar in the beets. The ratio of the proteid nitrogen 
to the total in the dry substance ranged between 60 and 65 percent. 
Phere are radical differences in the composition of these Euro¬ 
pean oeets as we find them represented in their literature and those 
which we have studied. It is not feasible to go into the details of all 
of our analyses, but the general results may be expressed as follows: 
t he whole nutrition of the beet seems to be very greatly modified. 
1 he total nitrogen in our beets is decidedly lower than in the Euro-
