Notices to Correspondents. _We have this week been compelled to omit our usual NOTES ON BOOKS, &c._ W. W. (Malta) _is thanked for his suggestion_. _We fear, however, that the difficulties in the way of carrying it out, which are far more than he suspects, will still prevent our doing so, as we have often desired._ PETER THE SAXONIAN _is referred to our_ 1st Vol., p. 102., _where he will find that both Blair and Campbell were anticipated by Norris of Bemerton, who sang of_ "Angels' visits, short and bright." R. G. L. _The meaning and derivation of_ DITTO _are obvious. It means_ "the same," _from the Italian_ ditto, _the said_. TOUCHSTONE. _Music is sometimes engraved, sometimes printed from moveable types._ J. C., _who inquires whether Shelley first imagined the name of_ Mab, _has, we fear, never read Shakspeare's Romeo and Juliet, or Mercutio's account of "the Fairie's midwife." We almost envy him._ F. R. S. (Barkisland). _His Query shall appear, and_ we think _we may promise him a full and satisfactory Reply._ H. C. K., _and other Correspondents respecting the inscription at Dewsbury, are thanked_. A. B. _The line_ "And coming events cast their shadows before," _is from Campbell's_ Lochiel's Warning. H. B. C. _The Correspondent to whom H. B. C. refers us furnished his name and address. But perhaps our Correspondent's Reply had better appear_. W. H. T. (Salisbury). Ophiomaches _was written by the Rev. Philip Skelton_. _See further our_ No. 157., p. 415. _The other Queries shall have early attention._ D'OYLEY AND MANT'S COMMENTARY. _With reference to our Note in No. 157., a Correspondent informs us that an edition is now publishing in Parts at 6d. each, by Strange_ PHOTOGRAPHY. _Owing to the length of DR. DIAMOND's directions for the Paper Process in our present No., we are compelled to postpone many interesting communications. DR. DIAMOND's former articles are contained in our Nos. 151, 152, 153. and 155. All our Nos., however, subsequent to 148., contain communications on this interesting subject._ THE INDEX AND TITLE-PAGE _to our Sixth Volume will be ready very shortly_. BACK NUMBERS OF NOTES AND QUERIES. _Full Price will be given for clean copies of Nos. 27, 28, 29, 30. 59, 60, and 61._ "NOTES AND QUERIES" _is published at noon on Friday, so that the Country Booksellers may receive Copies in that night's parcel and deliver them to their Subscribers on the Saturday_. * * * * * Mr. Henri van Laun assists Gentlemen in obtaining a critical knowledge of the French, German, and Dutch languages.
