fairly eclectic spirit, cannot fail to be advantageous to the method of a cabinet arrangement, even if leading to no higher biological conception.
In the sketch of the literature of Lepidoptera we are somewhat appalled by being reminded that "eighteen languages at least are employed in entomological works at the present day." Class A, of which a knowledge is considered necessary, includes English, French, Latin, and German. Class B, important but less necessary, comprises Dutch, Swedish, and Russian. Class C, valuable, but still less necessary, contains Italian, Spanish, Portuguese, Danish, and its near ally Norwegian. Class D, sometimes wanted, as Polish, Czech, and Magyar. Class E, probably unimportant, in which is enumerated Croatian, modern Greek, and Japanese. We are consoled by the reflection that though we know many entomologists, we are unacquainted with any possessing such polyglot accomplishments.
The faunistic bibliography given by Mr. Kirby is an excellent compilation, containing all that must be consulted for a primary knowledge of the Lepidoptera of the various regions detailed. There is also to be found a good list of the principal "books on Lepidoptera in general."
