The Optical Magic Lantern Journal and Photographic Enlarger.
The Ashton-under-Lyne Photographic Society.—The committee of this society has decided to give certificates of merit to the members who produce the best pictures taken at the society’s rambles during this year, viz., for the best direct print, best lantern slide, and best enlargement.

Lectures on Canada.—The clergy are invited to correspond with Mr. A. F. Jury, 15, Water Street, Liverpool, who, on behalf of the Canadian Government, is prepared to give his services free, and supply lantern slides to give lectures on Canada, its social life, and its agricultural, mineral, and other resources. The only stipulation made is the use of a hall, a lantern, and an operator. The question of charge for admission is to be left with the clergy, and the disposal of such funds is to be left to their discretion to aid in their parish work.

Bamforth’s Life Model Slides.—Amongst the new slides and lectures issued by Mr. Jas. Bamforth, of Holmfirth, we find Harry’s pint, Wanderer reclaimed, Billy’s rose, Dimes and dollars, Two weavers, Drink, Old clock, and Santa Claus. Several songs, too, have been illustrated, such as the ‘‘Anchor’s weighed,’ ‘ Robin Adair,’ ‘‘ What are the wild waves saying,” ‘““Kver of thee,’ ‘‘Ye banks and _braes,”’ ‘‘ Gipsy countess,’ ‘‘ Lost chord,” ‘‘ Old sexton,” together with a number of popular songs.

Restoring the Illuminating Power of Mantles.—Those who use incandescent gas mantles, either for lantern work or the enlarging of photographs, will be interested to know that when the luminosity begins to wane after long use, it may in a measure be restored by blowing out the mantle from the inside whilst the gas is burning. © A convenient means for doing this is a small bent tube with an india-rubber ball at the outer end, a few vigorous squeezes of which will send a rapid cuzrent of air through the mantle.
Death of Mr. Thos. Allardice.—We regret to have to announce the death of Mr. Thos. Allardice, which took place at his residence at Hornsey, London, N., on the 19th ult. Mr. Allardice was well known in the lantern wholesale trade, having been engaged by the firm of Wrench and Son almost from the time the business was founded.
The Past Season.
in the way of direct inventions pertaining to the lantern proper (excepting perhaps forms of obtaining intermittent motion for cinematographs) and it would almost appear to be as one of our authorities recently stated, viz.:—‘There seems very little scope left for anyone of an inventive mind, seeing the lantern has now arrived at such a great state of perfection.”” Be this as it may, there is promise towards the latter part of this year of several useful adjuncts being introduced, particulars of which we shall give in due course. Cinematographic views have for some time past been in great demand, the sale of the Diamond Jubilee series of pictures being phenomenal, so much so, that even in the smallest out-of-the-way villages it would be a difficult matter to find many persons who have not seen this interesting scene depicted on the screen. According to the well-known law of there being no gain without a loss, the cinematograph gain has been to an extent at the expense of ordinary lantern slides, but matters will speedily right themselves again on this score, and it is presumable that the use of the cinematograph will finally settle down to the obtaining of records for scientific investiga

more or less serious,
have occurred with this instrument, but in every case they have been attributable to carelessness.
There have been rumours that by means of the cinematograph we are to attain to stereoscopic projection on the screen, but so far little has been achieved in this direction with this instrument.
A novel style of exhibition has been attempted in London, at Niagara Hall, in which a special form of lantern was used to project sections of a continuous picture on a huge circular screen, joining each section so that ten or more sections were used to make one complete view. For some reason or other (perhaps it was introduced too early in the season) this entertainment only had a run of a few days, although a large amount of money had evidently been spent in fitting it up. The particulars of this interesting apparatus were given in detail, with illustrations,
' in this journal for July last.
Acetylene lamps have been coming in for a lot of attention, and the number of patents which have been recently applied for in connection with generating apparatus betokens a
