and the quiet appropriation of other people's philosophic or scientific ideas, can hardly be held to lie in their moral quality unless we take impunity as our criterion. The pitiable jays had no presumption in their favor and foolishly fronted an alert incredulity; but Euphorion, the accomplished theorist, has an audience who expect much of him, and take it as the most natural thing in the world that every unusual view which he presents anonymously should be due solely to his ingenuity. His borrowings are no incongruous feathers awkwardly stuck on; they have an appropriateness which makes them seem an answer to anticipation, like the return phrases of a melody. Certainly one cannot help the ignorant conclusions of polite society, and there are perhaps fashionable persons who, if a speaker has occasion to explain what the occiput is, will consider that he has lately discovered that curiously named portion of the animal frame: one cannot give a genealogical introduction to every long-stored item of fact or conjecture that may happen to be a revelation for the large class of persons who are understood to judge soundly on a small basis of knowledge. But Euphorion would be very sorry to have it supposed that he is unacquainted with the history of ideas, and sometimes carries even into minutiæ the evidence of his exact registration of names in connection with quotable phrases or suggestions: I can therefore only explain the apparent infirmity of his memory in cases of larger "conveyance" by supposing that he is accustomed by the very association of largeness to range them at once under those grand laws of the universe in the light of which Mine and Thine disappear and are resolved into Everybody's or Nobody's, and one man's particular obligations to another melt untraceably into the obligations of the earth to the solar system in general.
Euphorion himself, if a particular omission of acknowledgment were brought home to him, would probably take a narrower ground of explanation. It was a lapse of memory; or it did not occur to him as necessary in this case to mention a name, the source being well known—or (since this seems usually to act as a strong reason for mention) he rather abstained from adducing the name because it might injure the excellent matter advanced, just as an obscure trade-mark casts
