Guignard himself we get the impression of the strict analogy of the 

 processes of fecundation as they occur in the two kingdoms. Under 

 the heading " General Exposition of Results" the author retraces the 

 subject matter already given : the fixity or constancy of the chromatic 

 rods as to number in the sexual cells; the appearance of and the 

 mode of reduction in the number of these rod? at a given stage; the 

 constitution of the nuclei, including a discussion of the individuality < ;' 

 the chromosomes; the existence of"' directive spheres" in all vegetable 

 cells; the role or function of these spheres which are distinctive organs 

 of the cells and, lastly, a review of the prevailing theories concerning 

 the phenomena of fecundation. Of this he says, " We see that fecun- 

 dation is not only a conjugation of nuclei, hut accompanying this act 

 is that of the fusion of two protoplasmic bodies whose essential cle- 

 ment- are represented in the directive spheres of the male and female 

 cells." 



While hovering so closely about the subject of heredity it was not to 

 be expected that it should go untouched. After noticing the theories
