60 BRITISH BUTTERFLIES.

 tematic arrangement, a knowledge of which will facili. 

 tate even our recreations in natural history, while it is 

 absolutely essential to carrying out the really scientific 

 study of any department. 



It is true, that the painting of a butterfly and the

 quite unconscious of their Latin names, their genus, 

 order, or anything of the kind ; but the interest of 

 natural objects is, I am sure, greatly augmented when 

 we acquire some insight, however dimly, into the won-

 to which a good system of classification serves, in some 

 degree, as an index. I say, " in some degree" as a sys- 

 tem framed in perfect accordance with that of nature 

 is a discovery rather to be desired than hoped for, with 

 the limited knowledge at present permitted to us. 



Though these Latin names are generally considered 

 as unwelcome excrescences on the pages of popular 

 natural history works, I would yet advise the young 

 entomologist to master them for once, and accustom 

 himself well to their use. He will not find the task a

 instances in which I have heard the almost infantile 

 progeny of my naturalist friends glibly mouthing these

 precise accuracy.
