are large cells filled with a matter as clear as water, and apparently 
of the nature of bassorin ; and that this bassorin-like principle is 
composed of minute cells, each with its cytoblast, so compactly 
aggregated in the interior of the parent cell, that from this circum- 
stance, and from their very equal refracting power, they form an 
apparently homogeneous mass.

Mohl has examined the stomates of Hyacinthus orientalis in 
their progress of developement. He finds them in their earliest 
stage a single quadrangular cell, rather broader than long, and 
either empty or filled with green molecular matter. In the next 
stage, this single cell is cut in two by a partition which is directed 
across the smaller diameter, and separates the molecular mass 
into two equal parts. At a third stage, the angles round off, and 
the partition is seen to be double, with an opening in its middle. 
Later still, the molecular mass is broken up into granules of chlo- 
rophyll, the original cell is become oblong, the passage through 
the double partition has acquired its full size, and the stomate is 
complete. {Linncea^ xii. 54?4. t. 5. )

In a valuable paper upon the successive formation of the 
parts constituting the fructification of Leguminosae, the authors, 
Messrs. Schleiden and Vogel, have clearly shown that in that 
case the carpellary leaf is originally a folded scale, and that when 
the ovules appear it is from the margins of that leaf, and not 
from the central point of the axis ; so that it seems clear that the 
latter must be considered the origin of ovules only in certain in- 
stances. {Peitrdge zur Entwickelungs-geschichte der Bliithentheile

The observations made by Mr. Griffith upon the ovule of Lo- 
ranthacese and Santalum have been followed by others on the part 
of M. Decaisne, who finds that in Thesium the structure of the 
ovule is of the same nature as that of Santalum. ( Comptes rendus, 
viii. 203.)
