TO OUR READERS AND CORRESPONDENTS.

SEVERAL papers have been received, but are necessarily postponed to

our next Number.

We regret that the Appendix to Dr. Ure's paper on Opium reached us too late for insertion in its proper place; it shall appear (in the present volume) in our July Number.

Want of time has prevented our compliance with Mr. Herapath's request.

F. R. S. is informed, that an excellent abstract of the papers read to the Royal Society is given weekly in the Literary Gazette.

MR. BRANDE'S MANUAL OF CHEMISTRY WILL BE

PUBLISHED EARLY THIS MONTH.
