*** Letters, stating particulars and lowest price, _carriage free_, to be sent to Mr. BELL, Publisher of "NOTES AND QUERIES," 186. Fleet Street. * * * * * NOTICES TO CORRESPONDENTS. We are again compelled, by want of space, to omit many Articles that are in type; among others, one by Mr. Hampson, on _King Alfred's Geography of Europe_; _Extracts from Accounts of St. Antholin's_, The Rev. Dr. Todd _On the Etymology of Armagh_; as well as many NOTES, QUERIES, and REPLIES; and our acknowledgments of COMMUNICATIONS RECEIVED. We are for the same reason under the necessity of abridging our usual weekly NOTES ON BOOKS, &c. R.M. JONES, Chesea. To the queries of this correspondent (No. 14. p. 217.), who inquired for the best Treatise on the Microscope, and where to purchase the most perfect instrument, we have received many replies, all agreeing in one point--namely, that Mr. Queckett's is the best work on the subject--but differing mostly as to who is the best maker. Mr. Jones is recommended to join the Microscopical Society, 21. Regent Street, where he will see some of the best-constructed and most valuable microscopes ever made; and then can make his choice. To correspondents inquiring as to the mode of procuring "_NOTES AND QUERIES_," we have once more to explain, that every bookseller and newsman will supply it regularly _if ordered_; and that gentlemen residing in the country, who may find a difficulty in getting it through any bookseller in their neighbourhood, may be supplied regularly with the _stamped_ edition, by giving their orders direct to the publisher, Mr. GEORGE BELL., 186.
