Fig. 8 is a photograph of the complete installation for projection 

 as it is arranged for the demonstration in the Royal Institution. 

 In order that the operator may be in close proximity to the Phono- 

 graph and to enable him to make sure that everything works well, 

 and to regulate the apparatus, he has before him a rectangular box 

 (Figs. 9 and 10) called "Chef d'Orchestre," but which is practically 

 a " Control Board," fitted with a voltmeter which acts as a speed 

 indicator, a frequency-meter which gives exactly the angular velocity 

 at each instant of the Phonograph — a starting gear with a series of 

 resistances, whereby the Phonograph is set in motion, and a two-way 

 commutator in connection with the differential motor. 



Lastly, Fig. 11 shows the complete installation of the whole 

 apparatus. Projector, Phonograph, " Chef d'Orchestre " or Control 

 Board, and a pump for compressed air, by means of which and a 

 special distributor the sound-waves are so intensified in volume that 

 they can be heard in a large auditorium such as the Hippodrome in 

 Paris, when it is filled by six thousand persons. 



Some of the original Speaking Films show/i at the 

 Royal Institution. 



The following speaking films were demonstrated by means of the 

 •' Chronophone " by way of showing its applicability to the repro- 

 duction of all kinds of vocal sounds. To begin with, vocal sounds 

 produced by animals. (1) A Gallic cock placed on a pedestal, where 

 he crows right lustily so that the whole audience could hear the loud- 

 sounding efforts of Chanticleer, and observe the characteristic move- 

 ments that accompany his vocalisation. (2) A den of lions with 

 their trainer. The growling of the animals, the dull thud of the 

 iron bar on the floor of the cage are reproduced with startling realism. 

 (M) Illustrates the reproduction of speech and accompanying gestures 

 by a person who is seen speaking through a telephone. (1) Showed 

 a musician playing on a banjo exhibiting the movements of the 

 fingers over the strings, and the fidelity with which musical sounds 

 elicited by the vibrations of strings can be reproduced. (.5) Showed 

 a festive gathering of Frenchmen, one of whom gives the toast of 

 " The King," and the company unite in singing " God Save the 

 King." (6) A sailor reproduces in stentorian tones, Kipling's 

 " Ballad of the Clampherdown." 



Colour Introduced. 



So far, the Cinematograph has been most successfully adapted 

 to reproduce movement in monochrome or in black and white. Many 

 attempts have been made to add the charm and fascination of colour
