the Marcgravia, which developed a pitcher for the honey. 
Somehow that plant—he had almost said had acquired a know- 
ledge—had found that it was necessary to adapt itself to the 
structure of the creature that came to it in order to bring about 
its cross-fertilization. When the humming bird went to sip the 
nectar, it was impossible to avoid its head being dusted with 
pollen. In some cases it appeared as if flowers were perfectly 
aware they would be visited by bees and insects that would bring 
them no pollen and render them no service; that they protected 
themselves by certain specialities of structure and development ; 
and so, many of the plants had a way of checkmating robber 
insects. 
Having given illustrations of this series, and of the process 
of fertilization in the orchid family, the Lecturer closed 
by observing that the more they thought of the great law 
of evolution, the more they saw that they were driven, not to 
agnosticism and atheism, but to a higher and nobler theism, and 
a larger conception of the great Creator than the childish 
conception of their former days, when everything was supposed 
to be made by special creation. 
The lesson on the whole was fairly summed up in the words 
that had been often quoted, but not too often : 
“Let knowledge grow from more to more, 
But more of reverence in us dwell ; 
That mind and soul, according well, 
May make one music as before, 
But vaster.”’
