THE SEED. 147 



What name is given to the entire kernel ? What 

 part, found in the Indian corn, is missing here ? 



Look at the body of a seed of four-o'clock and see 

 how many and what parts it has ? Look also at the 

 body of a pumpkin-seed. 



Examine the kernel of each of the kinds of seed 

 you have planted, and observe which consist of em- 

 bryo alone, and which are part embryo and part 

 albumen. 



At the same time, write in your note-book, as 

 before, the results of observation. For 'example, to 

 the question, Parts of the body ? write for Indian 

 corn, Parts of body? Albumen. Embryo. For 

 Pea. Parts of body f Embryo.
