construction of an optical instrument, pre¬ 
cisely similar to that which forms the eyes 
of existing insects and crustaceans, affords an 
example of agreement that seems utterly in¬ 
explicable without reference to the exercise 
of one and the same Intelligent Creative 
Power. 
“ Professor Muller and Mr. Straus have 
ably and amply illustrated the arrangements, 
by which the eyes of insects and crustaceans 
are adapted to produce distinct vision, through 
the medium of a number of minute facets, or 
lenses, placed at the extremity of an equal 
number of conical tubes, or microscopes; 
these amount sometimes, as in the butterfly, 
to the number of 35,000 facets in the two 
eyes, and in the dragon-fly to 14,000. 
“ It appears that in eyes constructed on this 
principle, the image will be more distinct in 
proportion as the cones in a given portion of 
the eye are more numerous and long; that, 
as compound eyes see only those objects 
which present themselves in the axes of the 
individual cones, the limit of their field of
