Therefore, 132 LIVING PICTURES. after this short digression, let us proceed with a reviewof present-day machines, noting so far as possible alltypical apparatus, and also such curious suggestions as«obtrude themselves on our notice. It is not possibleto give more than a general idea of these present-daymachines and ideas, for not only is space limited, butin some instances the makers courtesy has not permittedillustration, while in a few cases even description has^.been objected to. WARWICK BIOSCOPE. In describing this machine it must be mentioned thatillustrations of the very latest design are not yet avail-able, but views of last seasons pattern will serve to^.

I33 value in practical working. The machine is of the dogvariety, the dog being mounted between two guide-plates, and standing to the right of the lower sprocket-wheel attached to the handle. The film is drawn offthe upper spool by a sprocket-wheel, which is gearedto turn at exactly the same rate as the lower one. Inthe illustration (Fig. 145) this upper sprocket has justfed out a picture-length, which stands in a loop abovethe film-trap, ready to be drawn down by the nextstroke of the dog. The loop drawn down by the latteris continuously stored away on the bottom spool orautomatic take-up, which is so geared that it winds upthe film under even tension, despite increased di
