The Optical Magic Lantern Journal (February 1897)

The Optical Magic Lantern Journal and Photographic Enlarger. 39 to hand, they would serve to remind the pioneers of our Empire that we at home recognise that their loyalty and their interest in the Old Country is no less than our own. Many of the larger towns of the Empire are as well served in the matter of slides, etc., as London itself : my idea was to arrange that the set suggested should rather travel about the outskirts of civilisation, whereever a lantern and a few British subjects are found. I have no doubt that the clergy, schoolmasters, photographic societies, etc., would willingly lend their aid in arranging for the transmission of the slides to suitable localities in their own countries. If the plan suggested meets with approval, I do not think there would be any difficulty in collecting a firet-rate set of slides, or in finding the small amount required for the expense of shipping it across seas. It is not necessary to enter into details until the plan has been discussed by your readers, but if those who acquiesce in it will signify their approval by writing to me “gare of Editor,’ and mentioning a suitable slide or two which they are able and willing to contribute, I will report on results in next Journal. Any proposals, suggestions, etc. (especially from the Colonies themselves), will be highly valued. I am, etc.. BOMBASTES TRIPLE. QUICK ACTING CARRIER. To the Editor. Dear Str,—The form of quick acting carrier suggested by Mr. G. R. Bryce in your last issue is almost identical with one I invented about three years ago, the chief difference being that I dispense with the cog-wheel motion, and use a much simpler method of revolving the carriers. I have made a rough model and used it on several occasions with some degrec of success. If Mr. Bryce should ever be in this neighbourhood and will give me a call, I shall be glad to let him see my apparatus, ’ Tam, sir, yours truly. H. L. KERDEL.

If you know of any such set of slides, will you kindly let me know where I can obtain such, as I would then at once purchase one | < A y | Mr.P.S.

(Seeing that many exposures are made per second, and that the effects of which ‘‘ Bartos ’ speaks would take some considerable time, it is likely that a film to embrace this subject would have to beseveral miles long.

On the 21st ult., before the Military Society, Dublin, a series of lantern slides he showed that a certain degree of success had been attained from time to time, but almost invariably some accident happened, which brought the experiment to an unsuccessful issue, but he hoped during this year to construct a machine with a 4 horse-power engine, which starting for a hill would maintain a horizontal flight for a considerable distance.
