_Theory of the Earth's Form._--Have any objections to the received theory of the earth's spherical form, or any revival of the old "plane" doctrine, been recently noticed and controverted by _scientific_ men of known standing? BRUNO. [The old theory has been advanced, and even lectured on, within these two years; but no notice has been taken of it by scientific men.] _Carolus Lawson._--Who was "Carolus Lawson," of whom I have a good print, engraved by Heath. He is called "Scholae Mancuniensis Archididascalus," 1797. "Pietas alumnorum" is inscribed underneath, and on the back is written, probably by some grateful pupil-- "Cari propinqui, cari liberi, cari parentes, sed omnes omnium caritates _Archididascalus noster_ comprehendit."--_Cicero_ (verbis quibusdam mutatis). NEMO. [Mr. Charles Lawson was educated at Corpus Christi College, Oxford, and was presented by the president, Dr. Randolph, in 1749, to the place of Second Master of Manchester Grammar School; upon the death of Mr. Purnell, in 1764, he succeeded him as Head Master. The colleges of St. John, in Cambridge, and of Brazenose, in Oxford, can bear witness to the success with which he laboured for more than half a century in his profession, having received from the Manchester school, whilst under his direction, a very considerable number of well-grounded classical scholars. He died at Manchester on April 19, 1807, aged seventy-nine. Some further particulars respecting him may be found in the _Gentleman's Magazine_, vol. lxxvii. part i. p. 583.] * * * * * Replies. HAYBANDS IN SEALS. (Vol. iii., pp. 186. 248. 291.) I am sorry that in referring to a peculiarity in ancient seals under this title, MR. LOWER should have pinned to his notice a theory which I feel persuaded is quite untenable. It is surely something new to those who have directed their attention to the numerous devices upon seals to find that the husbandman had so low an opinion of his own social status as to reject the use of any emblematical sign upon his seal, when Thomas the smith, Roger the carpenter, and William the farrier, bore the elements of their respective crafts as proudly as the knight did his chevron or fess. But the question is one of facts. The following examples of the use of the "hayband" are now before me:-- 6 June, 7 Henry IV. Grant by John Dursley, citizen and armorer of London, to William Serjaunt Taverner, of Stanes, and another, of a messuage, &c. in Westminster. Seal of dark red was, about 1-1/2 inch in diameter; a hay-stalk twisted and pressed into the wax while hot, inclosing a space as large as a shilling, in which is a poor impression of a badly engraved seal; the whole very clumsy and rough.
