Fig. 227 represents such an embryo with the parts 
shown. 
Point out and name the parts of the embryo of an 
apple-seed; of a pumpkin-seed ; and of each of your

specimens successively, as in former exercises., Which 
of your seeds has the largest plumule before growth 
begins ? Have you any in which the embryo has at 
first no plumule at all ? 
Have you failed to find cotyledons in any em¬ 
bryo looked at ? * 
As the number of your observations increases, and 
their character varies, you will see more and more 
the value of your notes recording them. 
To the question of this exercise, Parts of Embryo ? 
you give the answers, as before, from direct observa- 
* If these experiments with seeds are made as early as April, 
in this climate, the children who have made them will he ready 
for more extended observations when planting in the garden 
begins. Most garden-seeds are too small to he separated into 
parts by young children. But, when growth begins, their parts 
enlarge, and a child, who has before studied larger seeds, will 
be able to identify the radicle, cotyledons, and plumule, without 
difficulty. In the kitchen-garden, a universal appendage of 
country-houses, the sprouting of the radish, onion, beet, parsnip, 
lettuce, tomato, carrot, cabbage, cucumber, etc., will furnish an 
excellent continuation of the study of seeds.
