CARBONATE OF AMMONIA ON CHLOROPHYLL-BODIES. 273 
which there was much aggregated matter and no chlorophyll- 
grains. A third leaf was examined 5 days after the drops had 
been given, and the aggregated masses appeared to be breaking 
up into small highly transparent spheres. In two, however, of 
the short central tentacles of this leaf the cells at their bases 
contained no aggregated matter and plenty of chlorophyll-grains. 
It is probable that if these tentacles had been examined two or 
three days earlier, an opposite state of things would have pre- 
vailed. In a third central tentacle from this same leaf there 
was still much aggregated matter in the basal cells; and here a 
few irregularly shaped chlorophyll-grains could be seen. In 
other tentacles from this same leaf, and from two other leaves 
which had been similarly treated, some of the aggregated masses 
had become granular, discoloured, and opaque; and this indi- 
cates that the solution had either been too strong, or that too 
large a quantity had been given. 
Drops of a strong filtered solution of raw meat were now 
placed on 7 reddish leaves, the tentacles of which all became 
much inflected and their glands blackened. After 223 hours 
they were syringed with water, and one leaf was cut off for exa- 
mination. The contents of five short central tentacles from this 
leaf were aggregated down to their bases, and not a grain of 
chlorophyll could be seen. Some of the aggregated masses were 
almost white with a faint tinge of green, and were moving 
quickly. In the long exterior tentacles which had not at first 
been touched by the infusion (that is, not until they had become 
inflected), the aggregation had not as yet travelled down to the 
basal cells; and here the grains of chlorophyll were quite dis- 
tinct. The infusion was too strong; for after five days one out 
of the six remaining leaves was dead; two others were much 
injured, with the outer tentacles killed, those on the disk, though 
immersed for a longer time, being still alive; the fourth leaf 
was considerably injured ; the fifth and sixth looked fresh and 
vigorous, with their glands, now of a red colour, secreting freely. 
Five of the short central tentacles from one of these latter leaves 
were now (¿. e. after the five days) examined: in three of them 
only a trace of aggregation was left, and plenty of chlorophyll- 
grains could be seen; in a fourth tentacle there were still some 
aggregated masses and a few chlorophyll-grains ; in a fifth there 
were many aggregated masses and some fine granular matter, 
and here no chlorophyll-grains were distinguishable. There can
