EXAMINATION OF THE SEEDS. 
I. December 20th, The seeds in inflammable air were only a little swollen, 
but did not vegetate, 
II. Those enclosed by air corrupted by breathing vegetated; but on the 15th 
of December the plants were of a yellow colour, and had perished 
before the 20th. 
III. When oxygen air , or common air , were added either to the inflammable 
air or the air corrupted by breathing , the seeds grew and flourished 
in exact proportion to the quantity and purity of the added air. But 
if only a small portion of either airs were added the plants soon 
perished. 
IV. The seeds in common air grew in the ordinary way. 
V. But those, on the contrary, surrounded by the oxygen air rose the first, 
appeared uncommonly vigorous, and were much finer and greener 
plants than any of the others. 
EXAMINATION OF THE AIR. 
I. No alteration was found in the inflammable air . 
II. The respired air was reduced from 12 to 101 cubic inches, one inch of 
which was fixed air, and the remainder azotic. 
III. In Expeiiments XI. XII. XIII. and XIV. the oxygen air had wholly 
disappeared, and we had remaining the mephitic air a in their genuine 
state. 
IV. There remained fiom Experiment XV. with the atmospheric air , 11 
cubic inches, one inch of which was found to be fixed air , and the 
remainder azotic.
