All these results were due to imperfect nutrition, the effect of which was

cohesion with the stem in proportion as vitality was low. Here were the 
same facts. The leaves on the fascicle of the Balsam Fir were of the 
same nature as the weak leaves described in the paper referred to. Mr. 
Meehan had also shown, at the Salem meeting, that sex was influenced by 
the condition of vitality. The male sex followed from a loss of vigor. 
Here the same law followed fasciation. The fasciated bunches in the

known as Willson's Early, the number of branchlets in the bunch was 
often greater than in other instances female organs were

Mr. THOMAS MEEHAN read a paper ** On ete to Darwin’s Theory 
of Fertilization through Insect Agency.” He said that the discoveries 
- of Darwin had steps wonderful apparent seas for fertilization 
through insect agency; but occasionally instances were found where with 
had been considered as objections to a full acceptance of Mr. Darwin's 
theories. The Salvia was an instance. The lower division of the anther 
acted as a petaloid lever, closing the throat of the corolla tube, which 
is this probable, as in cultivation the Salvia produces very little see
