WONDERS OF AN EYE. 345 



In those gigantic creatures whose fossilized bones 

 are all now remaining to tell us of their history, 

 the mastodon., and megatherium) and in such vast 

 creatures as the elephant and the whale, we behold 

 the great power, skill, and wisdom of God; but 

 here, in a little object which we may cover with 

 a pin's head or with a large grain of sand, is a 

 more wonderful instance of His infinite and amaz- 

 ing power than all these. The eye of a dragon-fly 

 is a good instance of a compound eye : and of all 

 the beautiful, radiant, gem-like objects that can 

 be selected for inspection through the microscope, 

 this is the most exquisite. Professor Miiller, the 

 great German physiologist, has with wonderful 

 patience and care dissected the eye of this insect, 

 and has given a most beautiful account of its 

 structure. On examining the eye of this insect, 

 even with a good pocket magnifying glass, such 

 as those commonly sold by opticians for a few 

 shillings, it will be found to present 

 the appearance of a beautiful net- 

 work, or very fine grating, as is EyeoftheDragon . Fiy , 

 shown in the cut. When a greater magnifying 

 power is employed, it will be seen that each space 

 in this network is a six-sided or hexagonal figure.
