* * * * * _Dr. Owen's Works_ (Vol. i., p. 276.).--The editor of the _Works of John Owen_ is informed, that in the valuable library of George Offor, Esq., of Hackney, will be found a thick volume in manuscript of unpublished _Sermons on the Fifty-third Chapter of Isaiah_, in the Doctor's own hand-writing, and apparently prepared for publication. The same library also contains two scarce pieces by Dr. Owen, which it is thought have never been reprinted: 1. _The Stedfastness of Promises, and the Sinfulness of Staggering_, opened in a sermon preached at Margaret's, in Westminster, before the Parliament, Feb. 28, 1649, being a Day set apart for Solemn Humiliation throughout the Nation. By John Owen, Minister of the Gospel. London, 1650. 4to. pp. 54.--2. _God's Work in Founding Zion, and his People's Duty thereupon._ A Sermon preached in the Abbey Church at Westminster, at the opening of the Parliament, Sept. 17, 1656. By John Owen, a Servant of Jesus Christ in the Work of the Gospel. Oxford, 1656. 4to. pp. 48. J. Y. Hoxton. * * * * * _Bactrian Coins_ (Vol. iii., p. 353.).--Has your correspondent read the book by Masson _On the Coins, &c. of Afghanistan_, published by Professor H. H. Wilson? There are also references to authorities in Humphreys _On Ancient Coins and Medals_. C. B. _Bactria._--BLOWEN will find some trustworthy information respecting Bactria in Professor Lassen's _Indische Alterthumskunde_, Zweiter Band, pp. 277. et seq. Bonn, 1849; and a list of authorities on the Græco-Bactrian coins in the same work, pp. 282. 283. (notes). C. H. * * * * * _Baldrocks_ (Vol. iii., p. 328.).--On looking over a vestry book belonging to South Lynn in this town, commencing at 1605, and ending in 1677, I find some Churchwardens' Accounts, and amongst them the two following entries, which may, I trust, assist "A CHURCHWARDEN," and lead to an elucidation of this word:-- "1610. "Janua. 17. ffor a _balledrick_ to ye great Bell, xxi_d._ "1618. "Novemb. 22. Item. for mendine of ye _baldericke_ for ye foore bell, vj_d._" From these entries it seems that the "baldrock" was something attached to the great bell. In most of the recent English Dictionaries the word is applied to furniture, and to a belt or girdle. But in a Latin Dictionary published at Cambridge in 1693, I find in the Anglo-Latin part the following:-- English. A bawdrick of a bell clapper. Latin. Ropali corrigia. And the English of "Ropali Corrigia" seems (notwithstanding the English version given with it) to be "_pieces of leather_," or "_thongs of leather_" to the bell clapper, but for what purpose used I do not know.
