Tus farcical result is only in accord with the usual red-tape procedure. After months of waiting, and presumably investigation and deliberation by one body of men, the matter is to be taken in hand by a second body.
Lixt the countryman and the claret, we ‘don’t seem to get any furrader.” However,
two will not make much difference.

The Optical Magic Lantern Journal and Photographic Enlarger.
From all I hear the latest oxygen generator is a good thing. It is completely automatic in action, at all events for an hour and a half or two hours, and few lectures last longer than that, and then five minutes’ attention will start it off again for a similar period of time.

During the past month a certain amount of improvement and modification has to the appliance, which was exhibited at the Town Hall, Kensington. With this aerial screen various adaptations may be shown, including persistence of vision to large audiences, pictures projected in space, stage ghost effects.

success, and the proprietors appear to be reaping @ rich harvest at one franc per head.
One of the latest apparatus is the theatrograph of Mr. R. W. Paul, of 44, Hatton Garden, E.C., an illustration of which is shown herewith. The apparatus is strongly constructed of steel, gun-metal, and aluminium, and of such size as to go between the condenser and objective of an ordinary lantern. The film containing the instantaneous photographs is drawn from the spool at the top of the instru. ment, and passes under
