C.— Abstract of the Records of Growth of the Plants. 
I. — Plants grown in 1857*. 
X 
The following list indicates the original arrangement of the experiments in 1857 ; 
but, as the records will show, beans sown and resown under shades Nos. 5, 10, and 11 
died before they had attained any material amount of growth ; and hence the products 
in these cases were not submitted to analysis. 
Series 1. With no other combined nitrogen than that contained in the seed: — 
1. Wheat ; in prepared soil. 
2. Barley ; in prepared soil. 
3. Barley ; in prepared pumice. 
4. Beans ; in prepared soil. 
5. Beans; in prepared pumice. 
Series 2. With a supply of known quantities of combined nitrogen beyond that con- 
tained in the seed; — 
6. Wheat ; in prepared soil. 
7. Wheat ; in prepared pumice. 
8. Barley ; in prepared soil. 
9. Barley ; in prepared pumice. 
10. Beans ; in prepared soil. 
11. Beans; in prepared pumice. 
And also — 
12. Wheat, Barley, and Beans, together ; in rich garden soil. 
Records of Sowing, and Early Stages of Growth, of all the Plants collectively. 
May 12. — The w^eighed seeds of wheat (Nos. 1, 6, & 7), of barley (Nos. 2, 3, 8, & 9), 
and of beans (Nos. 4, 5, 10, & 11) were respectively put into small bottles, a few 
septems of pm’e distilled water added to soak them, and then corked up. 
May 16. — The wheats (Nos. 1, 6, & 7), and the beans (Nos. 4, 5, 10, & 11), "were 
sown, and the pots removed to their places on the stand, and covered with the shades ; 
seeds all swelled ; some sprouting. 
May 20. — The barleys (Nos. 2, 3, 8, & 9), freshly weighed seeds (the soaked ones 
being abandoned), were set, and the pots removed to their position under the shades. 
May 27. — Nearly all show shoots above the surface, all of which look green and 
healthy. 
Jvme 2. — Wheat and barley plants two or three leaves each, healthy, but pale green. 
No. 4 beans (soil) healthy and vigorous. No. 5 beans (pumice) one plant up, with 
three leaves speckled with black spots ; the other plant blackened and apparently dead. 
Beans No. 10 (soil) and No. 11 (pumice) slightly speckled with black spots. 
June 3. — Commenced the daily passage of washed air over the plants, in quantity 
* The figures (Plate XY.) of the plants grown in 1857 are reduced from drawings taken, for the most 
part, about the middle of August.
