scarcity of insects with the marked conspicuousness of blossoms, 
this is the way the lesson is read by a most eminent physiologist : 
“Even the glowing hue of alpine flowers is accounted for by the 
attraction which brighter-colored individuals exercise upon t the 
insects, scarce in those heights and necessary for sapiens,

take up the topic here; but, without acceding to his genera

The snaieudios upon the importance of self- fertilization is what 
gives this essay its value. As a whole it fortifies the proposition, 
well laid down by Herman Mueller, which Mr. Henslow cites:— 
“that, under certain conditions, the facility for self-fertilization is 
most advantageous to a plant, while, under other conditions, the
