THE pages of this Journal are impartially open to all communications upon the subjects of Science, Scientific Literature, and the Arts; and it is requested that they may be forwarded to the Editor, at least one month previous to the period of the publication of each Number. We shall be happy to receive papers from Provincial Scientific and Literary Societies, and to publish them either on the part of the Society, or of their respective authors. Papers which are too long for insertion, as is the case with many which we receive, or which are deemed unfit for this publication, will be immediately returned to the source whence we receive them, with our reasons for their return. We are indebted to Mr. Merrett, of Liverpool, for the article on "the Architecture of London," and hope again to hear from him. The communication upon the subject of Gymnastic Exercises we have been obliged to abridge more than we could have wished. It is chiefly extracted from the works of Mr. Shaw, surgeon to the Middlesex Hospital. The short notice from E. S., upon the subject of Captain Head's Rough Notes," was unfortunately mislaid, and not found again till too late for publication. We cannot exactly see the advantage of the plan proposed by our correspondent at Droitwich; and, therefore, decline publishing his letter till we are more satisfactorily informed upon the subject. Mr. Mac Mullen's additional observations upon the existence of chlorine in black oxide of manganese, arrived too late for insertion in the present Number. Reviews of the Philosophical Transactions, of Dr. Turner's Elements of Chemistry, of Mr. Faraday's Essay on Chemical Manipulation, and of several other scientific works, have been postponed for want of room. We shall certainly notice them in our ensuing Number. The letter of F. R. S., and the paper signed "Inquisitor," are in reserve, as we conclude some material change must soon take place. An account of the several Courses of Lectures delivered during the season in the Royal Institution, and of the proceedings of the general and other meetings of the members, was intended for this Number, but the pressure of other matter, and the length of our report of the weekly evening meetings, has obliged us to delay its insertion. We are requested by Mr. Faraday to publish the following errors which occur in his work, entitled Chemical Manipulation, with their corrections. They are errors of the press, which are not self-evident, and might lead pupils into mistakes. |
