CONDENSATION OF NITROGEN.

five, 5 per cent, of a mixture of different constituents of the 
soil, or of substances which it was interesting to examine. 
The substances were sprinkled with pure distilled water and 
kept moist. 
In each series of five were planted, — 1st, small brown 
beans; 2d, white beans; 3d, green peas; 4th, barley ; 5th, 
oats. 
After a month, from the 16th of May to the 16th of June, 
the following was the result of the development of the above 
seed : — 
1. Sand and Rain-water. — Seed came up very sparingly, 
the plants scarcely a hand's span high, nearly all faded. 
2. Sand y Ashes and Rain-water. — 1st, did not germinate ; 
2d, very sparingly; 3d, tolerably well developed; 4th, very 
poor; 5th, somewhat better, but still very weak. 
3. Sand, Jlshes, TJlmic Acid from Sugar, and distilled 
Water. — 1st, poorly ; 2d, tolerably well ; 3d, very well ; 4th, 
did not come up ; 5th, very well. 
4. Sand, Ashes, Apocrenate of Ammonia prepared from 
Sugar and distilled Water. — None succeeded except No. 5, 
and this but very badly. 
5. Sand, Ashes, Humate of Ammonia from Garden Earth 
(Ammoniacal Extract of Humus,) distilled Water. — None 
came up. 
6. Sand, Ashes, Humic Acid from Garden Earth, and dis- 
tilled Water. — 1st, very beautifully developed; 2d, none came 
up; 3d, imperfectly developed; 4th, none came up; 5th, 
tolerably well developed. 
7. Sand, Ashes, Aqueous Extract of Humus, and distilled 
Water. — 1st, 2d, 3d and 5th, none came up ; 4th, imperfectly. 
8. Sand, Ashes, Ulmate of Ammonia prepared from Sugar, 
and distilled Water.— -1st, 2d, 3d and 5th, very beautifully 
developed ; 4th, imperfectly. 
9. Sand, Ashes, Humate of Ammonia from Bog Earth, and 
distilled Water. — 1st, 2d, 3d and 5th, very beautifully de- 
veloped ; 4th, did not come up.
