[49] DEATH OF PROFESSOR G. P. BOND.—In a letter dated Feb. 20, Mr Safford writes to the President of the Royal Astronomical Society "I regret to state that Prof. G. P. Bond departed this life last Friday morning (February 17th), at 9 o'clock, after very severe and prolonged suffering. I fear his death will cause a void in astronomical science, especially in America, which it will be found hard to fill." ASTRONOMICAL REGISTER.

We have to thank our correspondents W.L.B. and S. B. K., for their papers on Saturn's Satellites; our extract from Mr Lassell's letter was however partly in type. Letters from the Rev. F. Howlett, and Mr E. Hopkins, on the Sun's Diameter, and from Mathematicus, and W. M., on the Moon's Rotation, will appear, if possible, in our next; after which these discussions can only be continued on the conditions stated in paragraph 7, on the next page. Communications from F.B., H.C.C., H.I., E.H., H.P., Ignoramus, and others, some of which are in type, are deferred for want of space. The TITLE-PAGE and INDEX to Volume II will be delivered, if possible, with our next number. ERRATA in the article on Speculum Analysis in our last number.-Page 62, line 11, for 'received' read 'viewed'; line 17, for 'arm a' read 'arm r'; line 22, for 'local' read 'focal'; page 63, line 18, for 'nebula' read 'nebulæ'; and line 30, for 'process' read 'group.' RULES FOR CORRESPONDENTS. 1.-Communications for insertion in the Astronomical Register must be sent in by the 15th of the month. Articles received later cannot be inserted, unless containing notices of fresh discoveries, or otherwise of immediate interest. 2.-Each communication must be authenticated by name and address: although not for publication unless desired by the writer. 3.-The Editor is not responsible for any opinions expressed by correspondents: and cannot undertake in all cases to print the whole of any communication sent: neither can he undertake to preserve or return any MSS. 4.-It very much lessens the trouble of printing if communications are written on one side of the paper only; and it need scarcely be added, that legible hand-writing tends in a great degree to prevent errors, which with every care are liable to occur in printing scientific matter. 5.-As, owing to the numerous letters received, it is not in our power to furnish our correspondents with Proofs, it is very desirable that they should read over and correct their communications before sending them: when this is carefully done, there is every reason to expect that the MS. will be correctly rendered in print. 6.-Illustrations.-As a general rule, it is not within the means of a publication like the Astronomical Register, the circulation of which is limited, to give illustrations to letters received from correspondents, on account of the expense thereby incurred: those therefore who desire the introduction of wood-cuts, can either supply the blocks themselves, or the Editor will get them cut at cost price. The sketch must be made of a size suitable for insertion in the Register, and so far complete as to be ready to hand to the engraver, in order to avoid the delay and trouble caused when the design has to be redrawn.-Lithographic illustrations can be introduced upon similar conditions.—Notice of illustrations being required must be given early in the month. 7.-Communications not of general interest.-As it frequently happens that subscribers wish to write at length upon subjects which, owing to various circumstances, may not be deemed of general interest to the readers of the Register, such subscribers may have their letters inserted in the pamphlet form, or otherwise, so as to obtain the advantage of the circulation of the periodical. The expense will be about ten shillings for two pages, fourteen shillings for three pages, and for four pages and upwards at the rate of four shillings per page, but no communication of this character can be inserted singly, unless of two or more pages. Shorter letters will be postponed until sufficient are received to make four pages, of which the charge will be apportioned among the writers. N.B.-A page contains from four to five hundred words. 8.-Reprints, or Extra Copies.-Correspondents who require separate copies of their communications can have them at a charge of 7s. 6d. for 50 copies, if not exceding four pages, or 128. up to eight pages; or they can be supplied with extra copies of the Register at a reduction of 25 per cent, when more than three copies are required.—Notice must in all cases be given with the communication, when reprints are required. The Astronomical Register is intended to appear at the commencement of each month: the Subscription, (including Postage) is fixed at Three Shillings per Quarter, payable in advance, by postage stamps or otherwise. The pages of the Astronomical Register are open to all suitable communications: Letters, Articles for insertion, &c., must be sent to the Editor, MRS.GORTON, Stamford Villa, Downs Road, Clapton, N.E., not later than the 15th of the month. |
