BOOKS WANTED. _So many of our Correspondents seem disposed to avail themselves of our plan of placing the booksellers in direct communication with them, that we find ourselves compelled to limit each list of books to two insertions. We would also express a hope that those gentlemen who may at once succeed in obtaining any desired volumes will be good enough to notify the same to us, in order that such books may not unnecessarily appear in such list even a second time._ P. G. _We are not in a position to answer_ P. G.'s_inquiries. Why not try one of the series and judge for yourself?_ A GERMAN INVESTIGATOR, _who states that some important moves towards the "flying by man" have lately been made upon the Continent, and who inquires "what noblemen or gentlemen would be likely to foster similar researches in this country," should rather address himself to some of the journals devoted to mechanical science._ SCIOLUS. _The author of_ Doctor Syntax _was the well-known_ William Coombe, _a curious list of whose works will be found in the_ Gentleman's Magazine _for May, 1852, p. 467._ CHARLES DEMAYNE. _We have a letter for this Correspondent; where shall it be sent?_ ERICA _will find his illustration of Campbell's_ Like Angel Visits _anticipated in our_ 1st Vol. J. N. C. (King's Lynn). _We have one or two Replies on the same subject already in the Printer's hands._ A. J. V. (University Club) _will find his Query respecting_ Solamen miseris, &c. _in_ Vol. viii., p. 272., _and an answer respecting_ Tempora mutantur _in_ p. 306.
