same as those of the original. The cinematograph enables "living" or "animated pictures" of such subjects as an army on the march, or an express train at full speed, to be presented with marvellous distinctness and completeness of detail. Machines of this kind have been devised in enormous numbers and used for purposes of amusement under names (bioscope, biograph, kinetoscope, mutograph, &c.) formed chiefly from combinations of Greek and Latin words for life, movement, change, &c., with suffixes taken from such words as [Greek: skopein], to see, [Greek: graphein], to depict; they have also been combined with phonographic apparatus, so that, for example, the music of a dance and the motions of the dancer are simultaneously reproduced to ear and eye. But when they are used in public places of entertainment, owing to the extreme inflammability of the celluloid film and its employment in close proximity to a powerful source of light and heat, such as is required if the pictures are to show brightly on the screen, precautions must be taken to prevent, as far as possible, the heat rays from reaching it, and effective means must be provided to extinguish it should it take fire. The production of films composed of non-inflammable material has also engaged the attention of inventors. See H.V. Hopwood, _Living Pictures_ (London, 1899), containing a bibliography and a digest of the British patents, which is supplemented in the _Optician_, vol. xviii. p. 85; Eugene Trutat, _La Photographie animee_ (1899), which contains a list of the French patents. For the camera see also PHOTOGRAPHY: _Apparatus_. CINERARIA. The garden plants of this name have originated from a species of _Senecio_, _S. cruentus_ (nat. ord. Compositae), a native of the Canary Isles, introduced to the royal gardens at Kew in 1777. It was known originally as _Cineraria cruenta_, but the genus _Cineraria_ is now restricted to a group of South African species, and the Canary Island species has been transferred to the large and widespread genus _Senecio_. Cinerarias can be raised freely from seeds. For spring flowering in England the seeds are sown in April or May in well-drained pots or pans, in soil of three parts loam to two parts leaf-mould, with one-sixth sand; cover the seed thinly with fine soil, and press the surface firm. When the seedlings are large enough to handle, prick them out in pans or pots of similar soil, and when more advanced
