Results. 
'The late development of the stigmatic surface. : 
Ditto ditto dorsal suture. Want of connection between 
placentze and margin of carpel leaf. : 
Development of the parent cells, in masses subsequently 
confluent, and enclosed in an inorganic looking muco-mucila- 
ginous substance. 
Enlargement of these ; disappearance of nuclei (cytoblasts) ; 
appearance of a hyaline envelope, containing a grumo-mole- | 
cular nucleus, (without cytoblast). Division of this nucleus
