With this clue I had little difficulty in ascertaining that the eighteen volumes alluded to were preserved among the _Additional Manuscripts_ in the British Museum, Nos. 4960-4977., and were probably purchased of the bookseller named above. I can trace no copy of the sale catalogue of Sir Simeon Stuart's library; but this library must have belonged to the third baronet of that name, of Hartley-Maudit, co. Hants, who succeeded to the title in 1761. The manuscripts in question all belonged in the reign of Charles II. to Samuel Waker, painter-stainer, in whose handwriting many of them are, among which is No. 4964, thus entitled: "_Collections of Descents and Armes of the Gentry of Middlesex, whereof was noe visitation generall of the same County, before that made by Sir Henry St. George, Richmond Herald [in 1634], except 7 descents of these are entered in the old visitation of Hertfordshire made in a'o 1572; all the rest are the collections of mee_, RICH. MUNDY." It is evident that this is the volume referred to by Warton and Chalmers; and no less certain, that, by a careless blunder, the playwright _Anthony Mundy_ has been confounded with his namesake _Richard Mundy_, the painter-stainer, whose voluminous heraldic labours are recorded in the _Catalogue of the Harleian MSS._, Nos. 1529-1534., 1536-1566., 1570. 1571. and 1577. The Add. MS. 4964. is, in reality, only an incomplete copy by Waker of Mundy's original manuscript, preserved in MS. Harl. 1551. I beg leave to annex the three following Queries. 1. Did any relationship exist between Anthony and Richard Mundy? 2. What is the name of the bookseller who lived "opposite the Exchange" in 1777? 3. Can any copy of the sale catalogue of Sir Simeon Stuart's library be referred to in existence? F. MADDEN. Minor Queries. 17. _Margaret Maultasch--Arms of Halle._--In "Marcel de Serres' Journey in Bavaria and the Tyrol" (printed in Arliss's _Pocket Mag._ 1825), in describing the statues ranged round the mausoleum of the Emperor Mathias in the Franciscan churn at Innspruck, he says: "Amidst the Princesses, Margaret Maultasch may easily be discovered by the hideous conformation of her mouth, and her eyes which glow with sensual desires. The singular arms which may be seen over the gates of Halle, but too plainly betoken the shameful and licentious character of this insatiable female." Where can I read the life of this "hideous" personage? And what are the arms alluded to? She was Duchess of Tyrol, and her portrait is in the Chateau d'Eu; but I have never seen an engraving. G. CREED. 18. _Test of Strength of a Bow._--What is the test of the strength of a _bow_? Does the distance the bow throws the arrow increase in ratio to its strength? What was the length of the bows used in the good old times? _Were the bows then made of more than one piece?_ Is there any advantage in having bow of _more_ than _two_ pieces? What wood _were_ the _arrows_ made of? TOXOPHILUS.
