Then it was on the radiates, echinoderms, acalephes, polypes, entozoons, sponges, and infusoria, that he had for such a long time burned the midnight oil?

It must, indeed, be confessed that it was not on the radiates.

Now, in zoology there only remains to be mentioned the division of the articulates, so it must be that it was on this division that Cousin Benedict's only passion was expended.

Yes, and still it is necessary to select.

This branch of the articulates counts six classes: insects, myriapodes, arachnides, crustaceans, cirrhopodes, and annelides.

Now, Cousin Benedict, scientifically speaking, would not know how to distinguish an earth-worm from a medicinal leech, a sand-fly from a glans-marinus, a common spider from a false scorpion, a shrimp from a frog, a gally-worm from a scolopendra.

But, then, what was Cousin Benedict? Simply an entomologist—nothing more.

To that, doubtless, it may be said that in its etymological acceptation, entomology is that part of the natural sciences which includes all the articulates. That is true, in a general way; but it is the custom to give this word a more restricted sense. It is then only applied, properly speaking, to the study of insects, that is to say: "All the articulate animals of which the body, composed of rings placed end to end, forms three distinct segments, and which possesses three pairs of legs, which have given them the name of hexapodes."

Now, as Cousin Benedict had confined himself to the study of the articulates of this class, he was only an entomologist.

But, let us not be mistaken about it. In this class of the insects are counted not less than ten orders:
