320 THE PHOTOGRAPHIC NEWS. [May 15, 1885. space, Cd. per square foot will be charged. All pictures for exhibition must be sent mounted and framed. On the back must be affixed the artist’s name, address, title of subject, pro cess by which produced, and price (if for sale), frame included. On no consideration will any name, title, or other particulars be permitted on the front, as such will appear in the catalogue, and no pictures in Oxford frames will be admitted. The council undertake to unpack, re pack, and return all exhibits remaining unsold; all carriage must be paid by the exhibitor. The ut most care will be taken of the exhibits, but at the same time the Society will not hold itself liable for any untoward accident that may occur, with the exception of loss by fire, which is specially provided for. The council will undertake the sale of exhibited pictures at a comission of 10 per cent. Photographs coloured by hand may be exhibited, but will be excluded from competition. Photographs mounted on glass may be exhibited, but will also be excluded from competition. The hanging com mittee reserve the power of rejecting any pictures. Each ex hibitor must fill up a form, which can be obtained from the Hon. Sec., and forward it to him not later than December 31st, 1885 ; and all pictures must be sent carriage paid, so as to arrive not later than February 4th, 1886, addressed :—International Photo graphic Exhibition, Albert Institute, Dundee. Apart from photographs for competition, the council will esteem it a favour if those who have any interesting examples of the progress of photography will kindly lend them for exhibition. Medals will be awarded in the various classes by the judges. All communi cations must be addressed to the Hon. Secretary, D. Ireland Jun., Commercial Street, Dundee, N.B. Relation between the Molecular ‘Structure of Carbon Compounds and their Absorption Spectra.—By Professor W. N. Hartley, F.R.S.— In the preparation of solutions of certain compounds, a miligram-molecule—that is, the molecular weight in miligrams—was dissolved in 20 c.c. of a diactinic solvent, and made up to a given volume, generally 20 c.c. In this way, molecular weights were made to occupy equal volumes. Photographs of the absorp.ion spectra were taken through definite thicknesses of solution. The lines of tin, lead, and cadmium were used as references ; the positions of the bands were measured on the photographs by means of an ivory rule divided into hundredths of an inch, and those measurements were reduced by means of two curves to oscillation, frequencies, and wave-lengths. As far as possible, the absorption curves are drawn to a uniform scale. These curves indicate the molecular actinic absorption of each substance. The following deductions are drawn : — When an atom of nitrogen is substituted for an atom of carbon in the benzene or napthalene nucleus, the property of selective absorption is stilll retained. When the condensation of the carbon and nitrogen in the molecule of a benzenoid compound or tertiary base is modified by the addition of an atom of hydro gen to each atom of carbon and nitrogen, the power of selective absorption is destroyed. When the condensation of the carbon in quinoline is modified by the combination therewith of four atoms of hydrogen, the intensity of the selective absorption is reduced, and is not destroyed.—Chemical Society Reports. Compounds Containing Nitro-Cellulose, Suitable as Varnishes, and for making Leather Cloth.—William Virgo Wilson and Joseph Storey claim the use of acetate of amyl as a solvent for nitro-cellulose. Such a solution can be used as a varnish for an infinite variety of articles. When 200 parts nitro cellulose are mixed with 600 parts acetate of amyl, a mass of a doughy consistency is obtained, which can be used for any of the purposes for which celluloid is used. With the addition of castor oil, China clay, and a small proportion of certain essential oils, a compound suitable for the production of artificial leather may be produced.—Journal of Chemical Industry. Paper labels for acid bottles should be fastened on with strong glue, and afterwards soaked with melted paraffin, which can be easily applied with the aid of a hot glass rod. — American Druggist. Photographing a Bull—A photographer went into the country to take a bull from life. For two miles —and three pairs of bars—the chances seemed good for the bull taking the artist from life. Photographer now takes his bull from the hen-roost. —The Rye. Photographic Club. —The subject for discussion on May 20th will be “ On the Preparation of Backgrounds.” The Saturday out door meeting will be held at Bushey, near Watford, Herts. Trains from Euston at 1'35. Uo Oorrespondents. *,* We cannot undertake to return rejected communications. Leicester.—Under the circumstances the best method is to empty the vessel periodically, and refill. Wm. Mark.—The information has been posted to you. E. E. B.—1. The communication you are good enough to send ap pears in the present number. One can only conclude that they were not alike; but for all this both may have been equally good. J:D. Webster.—It is extremely improbable that you will have any trouble whatever if you explain the nature of the packages. It is well, however, to put them at the top of your bag, and to call attention to them yourself. When Custom House officers insist on examining dry-plate packages, one can usually arrange for the examination being made under such conditions as not to spoil the plates. Percy Sheard.—Write to Messrs Carl Norman and Co., Tun bridge Wells. A. T. Newington.—Thank you for the paper; you will receive a proof in the course of a few days. Interior.—1. We should be inclined to think it will render the results less satisfactory; but you can easily determine this by a trial. 2. Take away either and use the remaining one without shifting it. 3. We should prefer A; but a longer exposure would be required. This is, however, a very trifling drawback in the case of such work as you refer to. J. W. K.—When added in moderate quantities it does not lower the sensitiveness, and the decomposition to which you allude will not take place when the solutions are dilute. TEINBRIDGE.—It can be obtained from the Sciopticon Company, 26, Colebrooke Row, Islington, N. Colonist.—Call at our office when you come to England, and we will endeavour to assist you in obtaining what you wish for. J. A. Kay.—The address of the former is 31, Farringdon Street; and of the latter, Martin’s Lane, Cannon Street. S. J. Murphy.—It is quite unnecessary to employ a patent agent, as by consulting the index volumes at the Patent Office Library, Southampton Buildings, Chancery Lane, you can ascertain the numbers in a very short time. If you remit the price, together with a sufficient sum to cover the postage, to Mr. H. Reader Lack, Comptroller-General of Patents, 25, Southampton Buildings, London, W.C., you will receive the specifications by post; but the Patent Office will not make any selection for you. There are three volumes of abridgments of specifications relating to photo graphy, published by the Patent Office. Vol. I., price lOd.; vol. II., price 111d. ; vol. III., price 10]d. ; all post free from Mr. Lack. These abridgements extend from 1839 to 1876. A. Ackermann.—Take the instrument to the reputed maker, and ask him if it is a genuine one. From what you say, we are in clined to regard it as a forgery. W. T. G.—The shutter described by Mr. II. Chapman Jones in the last Year-Book will answer very well. V. L.—Use citrate of soda. Victor.—Mount the print in the usual manner, but taking care that there are no lumps. Roll well, and then sift on finely- ground pumice powder. If you now rub gently with the palm of the hand, you will be able to obtain a very pleasing matt sur face. P. and S.—Unless you dry it first, there will be a constant liability to break up under the strain. W. Atkinson.—Carbon is not always used, although it is usually the base of the pigment. A mixture of lampblack, crimson lake, and indigo gives a pleasing tint, but the crimson lake is liable to fade. he Agotographic Jlels. SUBSCRIPTIONS.
