Forms which are generally considered as parasites (Pediculinae, Gyropeltes, 

 Histriohdella) are of great service to their hosts.

The sex cells being parasitic do not undergo any special development, and are 

 accustomed at the same time to definite kinds of food-materials elaborated by the 

 soma of the individual. Fecundation leads to the union of sets of elements de- 

 rived from different parents (all »cell-organs« being directly transmitted), theor- 

 gans rearranging themselves to their greatest mutual advantage. As the Indivi- 

 duum , having lost its parasitic nature, has to assimilate its own food, special 

 functions, successively distributed over cell-organs , cells and groups of cells are 

 developed.
