have beards and small rudimentary husks. 
Preparation and analysis as described at pp. 543, 544. 
No. 4. — Beans (1857); two seeds; prepared soil ; without nitrogenous manure.

July 5. — Plants taken up* : — 
Preparation and analysis as described at pp. 543, 544. 
* After removal of the beans, a barley plant from the field was potted with its own soil which was 
comparatively dry, and placed under the shade without being watered, in order to see whether water was 
given off and condensed within the glass as freely as in the case of the experimental plants. It was so ; 
and hence it was concluded that the experimental soils were not too wet.
