(Potamogeton lucens). My figure Plate VI. fig. 105^. shows the foundation of the mammiferous embryo to consist at a certain period of two cells. According to Sculeiden's representation (/. c. fig. 15.) such is tlie case in CEnothera crassipes; and here the two cells have the same form and general ap])earance as in the ovum of Mammalia, though germinal vesicle-like objects are not present. The evanescent nature of the latter (already mentioned) may possibly explain their absence in the vegetable figure. Some of my delineations of stages rather more advanced may perhaps admit of comparison with those of Schleiden, in which the terminal shoots (punrtum vegetationis of Wolff) come into view, and the cotyledons begin to make their appearance.
