568 MR. J. B. LAWES, DR. GILBERT, AND DR. PUGH ON 
added), two stems and five small shoots:—(a) highest leaf touches the top of the shade, 
and 8 inches of it lie against the wet glass, by which it is injured ; ten leaves; three bare 
nodes; (4) 23 inches high; nine leaves, three upper green, others yellowish; nodes not 
clear of the sheath; not heading yet; (c) three small stems from the base, 6 to 8 inches 
high, ceased to grow, and apparently dying; (d) two small rudimentary shoots; ceased 
to grow, and dying. 
Main stems—lower leaves yellow or dead; those starting a few inches from the soil 
numerous, and 12 to 16 inches long; those higher up, 4 to 6 inches long, green, and 
healthy; apparently incapable of supporting all the shoots started. 
October 5.—Plants principally increasing in height of stem; three touch the top of 
the shade; upper leaves green. Shaded from the direct sun to prevent injury from the 
little aqueous lenses formed on the interior of the shade; yet sun apparently wanted 
for ripening. 
October 24.—-Shade entirely full of vegetable matter, some stems touching the top, 
and leaves touching on all sides. Season for growth about over; plants seemed stationary 
during some recent cold weather, but, the last few days being warmer, they have revived 
again. [This remark applies to all the Cereals. ] 
October 26.—Plants taken up; produce from each seed as under :— 
No. 1 (furthest from the ammonia-solution tube), a mass of tufted leaves at the base; 
five leaves higher up below any visible node, formed before the plants began to run up 
stem (it was the same with the other plants, and with the leafy growth last year); higher 
up five more leaves, four visible nodes, and a head; total height 30 inches; rachis 
1} inch; three barren joints, and six with unripe seeds. 
No. 2 (third from the tube), two dead shoots at the base, with several leaves each; 
twelve leaves higher up on the main stem, lower ones 6 to 9 inches long, upper ones 
shorter; four nodes visible; total height 28 inches; rachis 13 inch long, three barren 
joints, and six with glumes and pales, but still green. 
No. 3 (second from the tube), three stems: (a) 6 inches high; ten long narrow 
leaves; stem dead. (0) 24 inches high; fourteen leaves below the first node, and three 
higher up; two nodes visible; plant still growing and vigorous. (c) Height 31 inches; 
twelve leaves below the first node, and three above it; swelled at the top with a head 
not yet out. 
No. 4 (nearest the tube), seven plants—five being small shoots 2 to 8 inches high, and 
two main stems. As mentioned in respect to No. 1, and applicable pretty generally to 
the Cereals with ammonia, a dense matted mass of leaves below the first node near the 
base, 8, 12, and 15 inches long, with thick sheaths forming a dense coat at the base of 
the stem. These plants are individually as follow:—(a) 28 inches high; three nodes; 
rachis two inches long, with five barren joints, and seven with glumes and pales, and 
seeds forming, green. (6) 35 inches high; four visible nodes; rachis 23 inches long, with 
five barren joints and seven with glumes and pales, and shrivelled seeds turning yellow. 
The soil wet, soft, and loose, and not filling up the interstices among the flints.
