Position and arrangement of the embryo. Delphinium ; 

 Cabbage, Pea. Umbellifers, Ranunculacese, etc. The 

 endosperm in albuminous and exalbuminous seeds. 

 The cotyledons in Oak, Horse Chestnut and Walnut. 

 First sign of germination. Seed stimulated into life. 

 How after loss of electrostatic capacity the electrical 

 system of the seedling is maintained. How the seed- 

 ling is protected from possibly " injurious light- 

 frequencies. Provision for obtaining oxygen. The 

 probable function of chlorophyll. Chlorophyll and 

 haemoglobin compared. lyight and light-frequencies. 

 Protection of young buds. Gummy and resinous secre- 

 tions of various plants. How Nuts and Horse Chest- 

 nut seeds protect themselves when injured. Oak 

 seedling from horizontally potted seed, illustrated and 

 described. The first growth, seed in two halves. The 

 radicle, plumule and "collar" attachment of the 

 cotyledons. Seedling from a seed potted apex down- 

 wards, illustrated and described. Manner in which 

 the leaf buds are borne upon the plumule. Seedling 

 from seed potted apex upward, illustrated and des- 

 cribed. A curious growth. Other seedlings illustrated 

 and described. One in which, the seed being potted 

 apex downward, the plumule issued from the base of 

 the seed. Suggestion of a synapse at the jimction of 

 the plumule with the radicle. Growth of the radicle 

 before formation of the plumule. Reason for want 

 of iiniformity in development. First view of the coty- 

 ledons. Seedlings grown in the open ground. 

 Different development. A Phillipine, illustrated and 

 described. SeedUng with one radicle and six shoots, 

 illustrated and described. Seed of the Ardisia 

 Japonica. Shoots on the hypocotyl of the Linaria 

 Bipartita. Other seedlings, illustrated and described. - 

 The electrical structure of the radicle. How the root 

 filaments pick up current from the earth. Filaments 

 pierce the membranous covering of the radicle and 

 connect with conductors within it. The radicle, illus- 

 trated and described. More about pot-grown seedlings. 

 Final view of the cotyledons.
