society, and there are perhaps fashionable persons who, if a speaker has occasion to explain what the occipat 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 minutiae 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 discredit on a good commodity, and even on the retailer who has furnished himself from a quarter not likely to be esteemed first-rate. No doubt this last is a genuine and frequent reason for the non-acknowledgment of indebtedness to what one may call impersonal as well as personal sources: even an American editor of school classics whose own English could not pass for more than a syntactical shoddy of the cheapest sort, felt it unfavourable to his reputation for sound learning that he should be obliged to the Penny Cyclopaedia, and disguised his references to it under contractions in which _Us. Knowl._ took the place of the low word _Penny_. Works of this convenient stamp, easily obtained and well nourished with matter, are felt to be like rich but unfashionable relations who are visited and received in privacy, and whose capital is used or inherited without any ostentatious insistance on their names and places of abode. As to memory, it is known that this frail faculty naturally lets drop the facts which are less flattering to our self-love--when it does not retain them carefully as subjects not to be approached, marshy spots with a warning flag over them. But it is always interesting to bring forward eminent names, such as Patricius or Scaliger, Euler or Lagrange, Bopp or Humboldt. To know exactly what has
