The Optical Magic Lantern Journal (December 1896)

We have also in the same district, within two miles, the home of the great naturalist, Dr. Darwin, where all his work was carried out. His widow died there a few weeks ago, and is buried in the little churchyard, where his brother is also buried. Downe House, his study, is just as he left it. Naturalists come from all over the world to see it. Any respectable person is generally shown over the house. Theo we have Sir John Lubbock’s home at High Elms, Down, Kent, in the same village; anyone could take views of them all in an afternoon’s walk, and we are just restoring the old house, Blackbrook Manor, Bickley, Kent, in which George Eliot wrote ‘‘ Romola.” These are a’l close together. Yours truly, Bromley Common, Kent. G. W. SMITH, P.S.—I should like to exchangea few slides with Mr. Albert Tranter. ——:0:—— YroS OL SEN” 9X2 IVY Oro) Détes and Queries. — NOARD* both for lantern and domestic illumination, but have never had the slightest mishap, consequently are unable to give any experiences such as you wish. H. S.—You will find Mr. Field's address on reference to their advertisement in last issue at the bottom of page Xxvil. The prices of the screen are there given. J. @. Tait writes :—(1) Can you tell me how to “ make fist’ tubing to jets ? Strings are a nuisance, and the grips I have tried are useless. (2) Can Clarkson’s regulator be re-covered ? The one I have is decomposing, and as aconS>quence is of no use. (3) I would like to add the Aphengescope to my lantern outfit ; a dealer tells me it is of no use with incandescent gas. Is this so? Ans.— (1) The best way is to get tubing that is small enough to have a good grip on the connection on which it is sprung. Perhaps the end of your tubing has become stretched : anything are opposed at firet, especially if there is any permanently, if so cut off an inch or so; it is also a good plan to roll the end of the tubing back on itself. (2) It is quite possible that you allude to a wedge form of regulator made some years ago by the firm you mention; if so, itis quite possible to recover it. But if the firm have, as we think, discontinued this particular make, it is questionable if it will pay you to have a new cover made, Some time ago they introduced their Duplex regulator ; the bellows portion of this is encased in brass. However, it may be worth while to write them. (3) The most satisfactory form is the double one used in conjunction with two limelight jets and two lanterns; with incandes| cent gas you will not get any results worth speaking of, | even with a very small disc. question (which we do not quote), the two makes are identical in every reapect, and probably are made by the same person. F. E, Ives.—On looking at the manuscript we find that you are quite correct in stating that in your letter the word ‘invention’ should have been printed instead of “ inventor."” In answer to your last ; Lanternist.—You do not state whose jet you are using, but it is evidently a powerful one. To prevent the pin fusing, we can only recommend that you use a much thicker lime so as to prevent the great heat from reaching the pin. We think you could get such limes from Messrs. Willway, of Bristol, as they advocate same for use with their ‘Gwyer Jet.’ Thanks for your good wishes. Please note that you addressed your letter to our old address, viz., Chancery Lane. J. J. Price writes :—Having seen in your advertisements that Peek, Frean & Co., give slides gratis to lanternists, perhaps you can tell me of other firms that do likewise, as 1 find such slides ueeful for filling up wken giving entertainments. 4Ans.—Last year slides were supplied by Elliman’s Embrocation Company, and Bird’s Custard Powder Company, but we have not heard that they intend doing so this season. A.W. R.—If you obtain the January numbers of this journal for the last few years you will see from the index for the previous year the names of the articles contained in the volumes. (1) The piece of camphor need not be larger than a Spanish nut. (2) By pouring off the oil and drying the wicks after use, the wicks will last in good order much longer than if continually in the oil. (3) | Aconvenient wick cuttersold by Perken, Son & Rayment, k Acetylene (Rev.)—We have used acetylene extensively will trim the wick evenly at one operation, and will also leave a nice even edge free from dragged out threads. R. S. Stevens—We consider the set of pictures (animated) of dancing Highlanders among the worst, as they appear on the screen as though the figures were suspended by strings from each joint, which gives a “ floating '’ effect. A general street scene will suit your | purpose much better. Western Calcium Light Co. (Detroit)—We called on the firm about which you wrote, and learned that they had received a letter from you about the same time. This firm are the makers of the particular form of lantern about which you enquire, and doubtless they will have written you ere this. J. Cocks.—The intenion of the writer of the article was to convey the meaning, that as plates are cheap and such developers as mentioned are easy to work with, slides are made in such quantities from all sorts of negatives, that many deserve the name he applies to them, and not, as you appear to take it, that the particular developer gives bad slides. Bright Light.— We consider that the restrictions relative to acetylene imposed by the Insurance Companies, etc., are only temporarily, and you may take it for granted that acetylene has come tostay. Most new things worth likelihood of their opposing established interests. J.D.C.—We have often used a generator of the form you describe, and have been unable to discover any danger in connection with same. Geo. Breck.—Thanks for the package; it will have attention in our next. E. Dunmore.—Unavoidably held over. S.S.—Part of the groove in the dissolving plug is stopped up, and requires cleaning out. You must of course remove the screw at the-end of the plug to get it out. Compliments of the Seargon tom TO ALL, <.
