tins cavity that the seeds are found, which in the fruits 
above mentioned are called pips. 
44. If we examine the seed well, we will find that it is 
composed of a pellicle enclosing another part, called the 
almond. It is within this almond that we find the em¬ 
bryo, containing the germ of the new plant. 
45. When the seed is placed in circumstances favorable 
to its development, it germinates, and gives birth to the 
radicle , that plunges into the earth to form the root, and 
the plumicle , that grows upward to form the stem. 
46. The first leaves that appear, after germination, are 
called cotyledons ; and if a plant has but one of the.u; 
leaves, it is called a monocotyledon: if it has several, it 
is called a dicotyledon . Plants that spring up without 
leaves, are called acotyledons.

LESSON VIII. 
GERMINATION. 
47. When a seed is put in the ground, the moisture 
causes it to swell; the pellicle that surrounds it is weak¬ 
ened, and the embryo bursts through. Vegetation then
