pockets they lie in the same plane, but in a short time twist about 
80 as to be in parallel planes. In this position, what may be called 
the knees of themass are turned to the side opposite to the groove, 
: and present to the cleft of the stigma, when the insect alights, what 
was before the outer edges of the mass. When moistened with 
warm water, the pollinia resume their original position. This last 
experiment I made with the pollen of A. Cornuti, Decaisne.

As the title, given in full, indicates, this little work brings toge- 
ther a class of facts constituting a new and most important chapter 
in Botany. It was time for the separate observations to be com- 
bined and the results introduced more directly to the student, and 
We are rejoiced to learn that Dr. Gray proposes a fuller statement 
of them. “The book is attractive in form, and we hope may lure the __ 
young to our favorite study. To more mature minds, imbued with 
a love of Nature, it cannot fail to prove of great interest. We find 
a little obscure the brevity of the account of the insect fertilization 
of Iris, and venture to question the dictum that such plants as Silene 
and Robinia viscosa capture insects by accident. a
