In several different places I have discussed the existence and length of what the mathematicians of the sixteenth century _used_, and those of the seventeenth _talked about_, under the name of the _geometrical foot_, of four palms and sixteen digits. (See the _Philosophical Magazine_ from December 1841 to May 1842; the _Penny Cyclopædia_, "Weights and Measures," pp. 197, 198; and _Arthmetical Books_, &c, pp. 5-9.) Various works give a figured length of this foot, whole, or in halves, according as the page will permit; usually making it (before the shrinking of the paper is allowed for) a very little less than 9-3/4 inches English. The works in which I have as yet found it are Reisch, _Margarita Philosophica_, 1508; Stöffler's _Elucidatio Astrolabii_, 1524; Fernel's _Monolosphærium_, 1526; Köbel, _Astrolabii Declaratio_, 1552; Ramus, _Geometricæ_, 1621. Query. In what other works of the sixteenth, or early in the seventeenth century is this foot of palms and digits to be found, figured in length? What are their titles? What the several lengths of the foot, half foot, or palm, within the twentieth of an inch? Are the divisions into palms or digits given; and, if so, are they accurate subdivisions? Of the six names above mentioned, the three who are by far the best known are Stöffler, Fernel, and Ramus; and it so happens that their subdivisions are _much_ more correct than those of the other three, and their whole lengths more accordant.

"Plurima gemma latet cæca tellure sepulta, Plurima neglecto fragrat odore rosa." S.W.S. _Emmote de Hastings._-- "EMMOTE DE HASTINGS GIST ICI" &C. A very early slab with the above inscription was found in 1826 on the site of a demolished transept of Bitton Church, Gloucester. By its side was laid an incised slab of ---- De Bitton. Both are noticed in the _Archæologia_, vols. xxii. and xxxi. Hitherto, after diligent search, no notice whatever has been discovered of the said person. The supposition is that she was either a Miss De Bitton married to a Hastings, or the widow of a Hastings married secondly to a De Bitton, and therefore buried with that family, in the twelfth or thirteenth century. If any antiquarian digger should discover any mention of the lady, a communication to that effect will be thankfully received by H.T. ELLACOMBE. Bitton. _Boozy Grass._--What is the derivation of "boozy grass," which an outgoing tenant claims for his cattle? Johnson has, "Boose, a stall for a cow or ox (Saxon)." A.C. _Gradely._--What is the meaning, origin, and usage of this word? I remember once hearing it used in Yorkshire by a man, who, speaking of a neighbour recently dead, said in a tone which implied esteem: "Aye, he was a very _gradely_ fellow." A.W.H.
