496 THE PHOTOGRAPHIC NEWS. [July 31, 1885. with a focussing glass or simple magnifier at the apex of the cone. Such an arrangement not only enables the operator to focus with care, but it permits him at the same time to look about him so as to study out a position for the best view. Law of Emanation of Light from Incandescent Substances. —By W. Moller (Ann. Phys. Chern. [2], 24, 266, 281).—The law of cosines for the emanation of light irom incandescent sub stances has been based hitherto rather on the analogy of light with heat-rays, than on experimental evidence. By means of a simplified form of Wild’s photometer, the author has given an empirical proof of the law, and has tested the relative intensity of the more important incandescent lamps.—Journal of the Chemical Society. “ Taking ” a Photograph.—A correspondent is good enough to send us the following cutting from the Birmingham Daily M.ail of the 18th inst. :—There was a misunderstanding between two people at the Police Court the other day, such as would be almost sufficient to make the fortune of a present-day farcical comedy. A woman was charged with stealing a photo graph. The prosecutor’s evidence was being taken by his solicitor, when something like the following dialogue took place :—The Solicitor : Well, you found that your photograph had gone ? Witness: Yes. Solicitor : And when was it taken ? Witness : When was it took ? Oh, seventeen years ago last May—the week after I was married. Solicitor : Good gracious, man ! What are you talking about ? You charge the prisoner with stealing your photograph only yesterday. Witness: So she did. Solicitor: But now you say it was taken seventeen years ago. Witness : Yes ; that was when it was first taken. Solicitor : Oh, I see. You have lost it more than once, then ? Witness: No, sir. It’s always hung on my parlour wall till yesterday. Solicitor: Well, and then it was taken, wasn't it ? Witness : No, sir. I missed it in the afternoon, but it had been taken seventeen The Magistrate’s Clerk : What does it all mean ? Witness : It was taken on the sands at Ramsgate. My wife had hers took, too. Solicitor: Oh, I see what he means, sir. He’s rather confused about the word “taken.” Now (to witness), when you say it was taken seventeen years ago, you mean that you were photographed, eh? Witness : Yes, sir. Solicitor : And when I said taken, I meant it was.taken away— stolen. Now, then, we shall get on. Witness: Yes, sir. Solicitor : Now we will begin right at the beginning, so as to be quite clear. Where were you at the time it was taken? Witness : I had just gone out of the room, sir. Solicitor : How could that be ? How could they take your photograph when you were out of the room ? Witness: Of course they could, sir. If I had been in the room I should have took good care that it wasn’t took. Solicitor (to the Magistrate) : I am afraid he’s getting rather confused again, sir. Witness (angrily): Who is confused ? The Magistrate’s Clerk: I am. Whatever are you all talking about ? (To Witness): Was the photograph after wards brought to you by the prisoner ? Witness : No, sir. I took it away myself. (Complete collapse of the whole Court.) Nothing further could be got out of the witness until, by a happy inspiration, the magistrate told him to say what he had to say without the assistance of any questioning. Left to himself, witness soon placed the matter in a perfectly clear light.” Freaks of Girls.—Speaking of freaks of girls, a corres pondent writes to a Western paper :—“ Well, I was going to tell of a feminine freak in the less useful line of amateur photo graphy. The maiden’s modesty was not acute enough to keep her from self appreciation. She had never been satisfied with the portraits which professional photographers made for he r. She felt sure that her sweetest expression had not been caught by the camera, as she often saw it in her mirror. Having a camera with the usual attachment for taking instantaneous views, she has spent her leisure hours for a week or two in making nega tives of her own visage. A string hitched to the trigger of the instrument enables her to be both operator and subject; and thus, in the privacy of her chamber, with no spectator to hinder or make afraid, she transfers her smiles and frowns to the plates, to be subsequently developed into photographs, in case she deems them worth it. She has thus far made one hundred and sixty-seven different pictures of herself.”—Photographic Times. Photographic Club.—The subject for disctssion at the next meeting, on August 5th, will be " The Action of Various Sulphites and Bisulphites in the Developer,” Outdoor meeting at Uxbridge, Bank Holiday, Aug. 3 ; trains from Bishops’ Road at 10.6 a.m. Uo Oorrespondents. *,* We cannot undertake to return rejected communications. H. M.—Morally and legally it belongs to your employers, not to you. Rob. F. Dixon.—1. No varnish is satisfactory unless every trace of hypo is washed out of the film ; but if proper care is taken, the following answers well: — Commercial white hard varnish 2 pint Methylated spirit 1 pint 2. Equally good, as far as we can judge. 3. We cannot very well suggest, as the requirements of persons are so various; your best way will be to look at some of the forms which are offered for sale. 4. It is best to doit before. C. M.—Under the circumstances you should have no difficulty in obtaining the kind of appointment you require, and you should either answer advertisements, or advertise yourself. Lens.—No. 1 is about 1, No. 2 about No. 3 about No. 4 about f, and No. 5 about /. A. Griffiths.—1. Nitrate of silver 10 grains Water 1 ounce Add enough of a saturated solution of cyanide of potassium to re dissolve the precipitate which is formed at first. 2. From any copper plate printer or dealer in printing material (Winstone, 100, Shoe Lane, London). The cost should be Jess than one shilling. 3. About one-eighth of an inch, but they are mounted on wood blocks so as to bring them up to type height. 4. A Winchester quart; but do not forget that a Winchester quart bottle holds half-a-gallon. G. W. V.—It would take far too much space. You must consult some old book on photography. Progress.—1. If you can get a quick plate, it will be all the better. 2. On the whole you will find the next size larger lens to be rather more suitable, but the advantage will not be very great. 3. The ordinary pyro and ammonia. J. Bullock.—Thank you; use has been made of it. A. REVON.— Alum 1 part Citric acid 2 parts Water 10 „ A. Y.—The ordinary carbon tissue. Obtain the Autotype Manual, published by the Autotype Company, 174, New Oxford Street. Amateur.—1. Nothing is better than very thin glue, to which a little methylated spirit has been added. 2. The exposure must be increased in proportion to the relative areas of the stop. Thus, with a stop of half the diameter (or one-fourth the area), the ex posure must be increased four-fold A. E. S.—It appears to be a basic chromate of lead, and as it is very imperfectly fixed to the paper, there will be no difficulty in removing the greater part of it by a sponge and warm water. 2. We do not know of any method for doing this. R. T. Wall.—Can you send us a sample of the varnish, and wo will try the experiment ? It should be of great value for the pur pose mentioned. R. II. Preston.—Good use has been made of it, as you will see. Uge Ahotographit ews. SUBSCRIPTIONS. Including Postage to any part of the United Kingdom:— Yearly ... 15s. Od | Half-Yearly ... 7s. 8d.
