_Tick_ (Vol. iii., p. 357.).--MR. DE LA PRYME'S suggestion as to the origin of the expression "going tick" is ingenious; nevertheless I take it to be clear that "tick" is merely an abbreviation of ticket. (See Nares's _Glossary_, and Halliwell's _Dictionary of Archaic and Provincial Words_, under "Ticket.") In addition to the passages cited by them from Decker, Cotgrave, Stephens, and Shirley, I may refer to the Act 16 Car. II. c. 7. s. 3., which relates to gambling and betting "upon ticket or credit." C. H. COOPER. Cambridge, May 3. 1851. [In the _Mirrour for Magistrates_, p 421., we read:-- "Of _tickle credit_ ne had bin the mischiefe." "Tickle credit," says Pegge, "means easy credit, alluding to the credulity of Theseus."--_Anonymiana_, cent. ii. 44. Mr. Jon Bee, in his _Sportsman's Slang Dictionary_, gives the following definition:-- "_Tick_", credit in small quantities; usually _scored_ up with chalk (called _ink_ ironically), which being done with a sound resembling 'tick, tick, tick,' gives the appellation 'going to _tick_,' '_tick_ it up,' 'my _tick_ is out,' 'no more _tick_!'"] _Hylles' Arithmetic_.--Having seen it mentioned in the public papers that a copy of the first edition of Cocker's _Arithmetic_ (considered unique) was lately sold at an exceedingly high price by Messrs. Puttick and Simpson, I am induced to send you a {410} copy of the title-page of an arithmetical work in my possession which seems a curiosity in its way; but whether unique or not, my slender bibliographical knowledge does not enable me to determine. It is as follows: "The Arte of Vulgar Arithmeticke, both in Integers and Fractions, _devided into two Bookes, whereof the first is called Nomodidactus Numerorum_, and the second _Portus Proportionum_, with certeine Demonstrations, reduced into so plaine and perfect Method, _as the like hath not hetherto beene published in English_. _Wherevnto_ is added a third Booke, entituled _Musa Mercatorum_: comprehending all the most necessarie and profitable Rules _vsed in the trade of Merchandise_. In all which three Bookes, the Rules, Precepts, and Maxims are _onely composed in meeter for the better retaining of them in memorie_, but also the operations, examples, demonstrations, and questions, _are in most easie wise expounded and explaned, in the forme_ of a dialogue, for the reader's more cleere vnderstanding. _A knowledge pleasant for Gentlemen, commendable for Capteines_ and Soldiers, profitable for Merchants, and generally _necessarie for all estates and degrees_. Newly collected, digested, and in some part deuised by a _welwiller to the Mathematicals_." "_Ecclesiasticus_, cap. 19. "Learning unto fooles is as fetters on their feete and manicles vpon their right hand; but to the wise it is a Iewell of golde, and like a Bracelet vpon his right arme. "_Boetius_. I. _Arith_. cap. 2.
