THE WEEKLY ENTOMOLOGIST. 
devoted their attention to one partic- 
ular branch, and have worked at 
that thoroughly. 
From these data we conclude that 
if all moderately developed Entom- 
ologists would be content to confine 
their Scientific zeal, — which like 
many other sorts of zeal is apt to run 
riot if left to itself — to one group, or 
to one family, the advantage to science 
would be incalculable ; provided, of 
course, that they did not by an un- 
lucky coincidence all fall in love with 
the same insect and there — by leave 
the rest to take care of themselves. 
Again we do not wish it to be thought 
that a more than average amount of 
knowledge in one particular, should 
imply a general ignorance of every- 
thing else. On the contrary we 
should recommend no would — be En- 
tomologist to devote himself to the 
Eupithecice or the Tinea before he has 
obtained by practical experience a 
general outline of knowledge. For 
let us remember, that in Entomology 
as well as in other matters, there are 
a few main facts which it is no credit 
to any one to know, but a great dis- 
grace to be ignorant of.
