The Optical Magic Lantern Journal (April 1903)

77 THE OPTICAL magic LANTERN JOURNAL the frame now made for exact registration,—reprinted and again similarly or oppositely treated to one’s heart’s content. All this may be done either in day or artificial light as the paper is insensitive to the latter, and only sensitive to the former when dry and not when wet. I therefore feel no apology is needed for my special liking for this process, which gives full rein to one’s fancy, and permits full play in the exercise of that “spice of devil” which should be in every constitution that is worth anything at all. I shall be pleased to give any further information on this simple artistic and most fascinating process to any who feel sufficiently interested to write me through the Editor of the paper. KRHRKKKK Thro’ our Lantern. “ ELGE LIST.” Every person connected with or interested in Cinematograph matters would do well to secure a copy of the above list, which is issued free every month, from Messrs. L. Gaumont & Co., 25 and 22, Cecil Court, Charing Cross Road, W.C. This monthly: circular is a list of new film subjects and of other productions issued by Messrs. Gaumont & Co., and in this month’s list we notice a number of interesting subjects from different parts of the world, together with several new comic films just added to the Elge collection. A number of announcements are made in the list concerning novelties of all kinds likely to interest Cinematograph exhibitors, amongst which mention is made of the Chronophone, a new invention combining Cinematograph and Phonograph, by which it is claimed that absolute synchronism has been obtained at last. It certainly will be a great advantage if complete, simultaneity of sound and action has been achieved, and we hope to have the opportunity of seeing the apparatus at work before long and reporting further in respect to same. The Elge list is sent free every month to those having sufficient interest in such matters to make application for it. We had an opportunity to examine some very fine Malarial Slides, published by Messrs. Newton & Co., 8, Fleet Street, London, E.C., from Negatives by Dr. Harold Spitta, of the Seamen’s Hospital. These slides supply a long felt want to all lecturers on Zyimotic and other diseases. We note one very interesting item to Vegetarians, a Mosquito with parasite in its proboscis was fed for 45 days on Bananas, and did not infect the fruit, but as soon as it was placed on a piece of meat the parasite was at once injected therein. The following is a list of the subjects which retail at 1/6 each slide :— 1. Filana Bancroft, male parental form. 2. Complete long sect through a Filariated Mosquito showing parasite in muscles. 3. Culex pipiens. 4. Culex pipiens proboscis. 5. Young Filaria in thoracic muscles of Culex. 6. . do. do. do. more mature. 7. do. do. do. do. 8. . do. do. do. do. 9.

Has received a very welcome addition in shape of a useful little book called, “Figures, Facts, and Formule of Photography.” Edited by H. Snowden Ward, Esq., F.R.P.S., Editor of Photogram. A wonderful amount of .information is pressed into a small space, and we must conevatulate the editor upon the results, he has evidently spared no pains to condense information, and our advice to all readers is to obtain, without delay, a cloth bound volume at 2/-, it will save its cost over and over again in a very short time during the season.
