ttentmechanism and no interval of darkness between suc-cessive pictures on the screen. The suggestion madeon page 31 therefore seems within a measurable distance•of realisation. THE RILEY KINEOPTOSCOPE. This machine is made in several patterns, thoughthe working arrangements are similar in essentials. Fig.190 shows the apparatus as constructed for insertionin the stage of an ordinary lantern for home use;while by another arrangement the apparatus slides on a front baseboardso that the picturemay be shiftedinto better positionalong the conicalbeam of light fromthe condenser.The motion em-ployed is a four-toothed claw in-serted to draw thefilm down and with-drawn previous torising. The ar-rangement is suchthat an amount of play equal to half the width of aperforation is afforded in order to avoid punchingan inaccurately gauged film. The apparatus may alsobe fitted as a camera. This machine has been shownunder the name Steenomatographe, an evidentderivation from the exhibitors surname.

Fig. 19c. PRESENT-DAY APPARATUS. 173^ NEWTONS ENGLISH KINEMATOGRAPH. This apparatus (Fig. igi) differs from the usual typein several important particulars. It may be adjustedbefore the condenser of any lantern body, but is itselffurnished with a supplementary condenser, which serves-for the final concentration of the light upon the film.The intermittent motion is obtained by a revolvingeccentric, which is always kept in contact with the film,,thus avoiding suddenshock. This eccen-tric is mounted on aswinging arm, andmay be shifted whenplacing a fresh film,in order to bring theview into register byslightly lengtheningor shortening thepath of the film. Thewhole apparatus maybe inverted for theexhibition of reverseeffects, thus obviatingboth rewinding andthe use of a prism.Chain-gearing is usedfor driving. An in-spection apparatus onsomewhat the same lines is made b}/ the same firm,and called the Newtonian Table Kinematoscope,the film being run under a magnifying eyepiece, andtinters bei
