the weight of each in tlie great scale of the universe, and the 
effect of each in the mighty whole, which St. Pierre has so well 
termed the harmony of Nature. He, and he only, who will 
look at an insect or family, or order of insects, from these varied 
points of view ; he who will not rest contented with the possession 
of a specimen, especially if it be a rare one, or with the observation 
of a single fact or two in its econom}^ or with its name and sup- 
posed place in the system, but will take such a wide range of 
vision as I have above sketched ; he only is worthy of the name 
<jf an Entomologist.
