I think the _Cambridge University Calendar_ will contain all the mathematical questions proposed in the Senate House for the period mentioned. Those from 1801 to 1820 inclusively were also published by Black and Armstrong (Lond. 1836), to accompany the revised edition of Wright's solutions. The problems from 1820 to 1829 inclusive are reprinted in vol. v. of Leybourne's _Mathematical Repository_, new series, and in vol. vi. those for 1830 and 1831 are given. In 1849 the Rev. A. H. Frost arranged and published the questions proposed in 1838 to 1849. Perhaps this may be found satisfactory. T. T. WILKINSON. _Reversible Masculine Names_ (Vol. viii., pp. 244. 655.).--If you allow _Bob_, you cannot object to _Lol_, the short for _Laurence_. Lord Glenelg and the Hebrew abba will not perhaps be held cases in point, but _Nun_, _Asa_, and _Gog_, and probably many other Scripture names, may be instanced; and _Odo_ and _Otto_ from profane history, as well as the Peruvian Capac. P. P. _The Man in the Moon_ (Vol. vi., pp. 61. 182. 232. 424.).-- "As for the forme of those spots, some of the vulgar thinke they represent a man, and the poets guesse 'tis _the boy Endymion_, whose company shee loves so well, that shee carries him with her; others will have it onely to be the face of a man as the moone is usually pictured; but Albertus thinkes rather that it represents {185} _a lyon_, with his taile towards the east and his head to the west; and some others (Eusebius, Nieremb. _Hist. Nat._, lib. VIII. c. xv.) have thought it to be very much like a _fox_, and certainly 'tis as much like a lyon as that in the zodiake, or as Ursa Major is like a beare.... It may be probable enough that those spots and brighter parts may show the distinction betwixt the sea and land in that other world."--Bishop Wilkin's _Discovery of a New World_, 3rd. edit., Lond. 1640, p. 100. "Does the _Man in the Moon_ look big, And wear a huger periwig; Show in his gait, or face, more tricks Than our own native lunatics?" _Hudibras_, pt. II. c. iii. 767. To judge from his physiognomy, one would say the Man in the Moon was a _Chinese_, or native of the Celestial Empire. EIRIONNACH. _Arms of Richard, King of the Romans_ (Vol. viii., p. 653.).--With respectful submission to MR. NORRIS DECK, and notwithstanding his ingenious conjecture that the charges on the border are pois, and the seal which he mentions in his last communication, I think the evidence that the border belongs to Cornwall, and not to Poictou, is perfectly conclusive.
