Now, as to the numbering:—It is a rule that of every date and denomination, one hundred thousand Notes—no more and no less—shall be completed and issued at one time. We know, therefore, that our solitary five is one of a hundred thousand other fives, each bearing a different number—from 1[2] to 100,000—but all dated 2nd Feb., 1850. The numbers are printed on each Note by means of a letter-press, the types of which change with each pull of the press. For the first Note, the press is set at “00001,” and when that is printed, the “1,” by the mere act of impression, retires to make room for “2,” which impresses itself on the next Note, and so on up to “100,000.” The system has been applied to the stamping of railway tickets. The date, being required for the whole series, is of course immovable. After this has been done, the autograph of a cashier is only requisite to render the Note worth the value inscribed on it, in gold. Footnote 2: To prevent fraudulent additions of numerals, less than five figures are never used. When units, tens, &c., are required, they are preceded by cyphers. “One” is therefore expressed on a Bank Note thus:—“00001.” While the printers are at work, manufacturing each series of Notes, the account-book makers are getting-up a series of ledgers so exactly to correspond, that the books of themselves, without the stroke of a pen, are a record of the existence of the Note. The book in which the birth of our own especial and particular “Five” is registered, is legibly inscribed, “Fives, Feb. 2, 1850.”
