The first edition of this work was written by my father, the late Mr. Lewis Wright, and was published in 1890.
The reception that it received testified to the fact that it met a long-felt want, and successive editions were published in 1895, 1901, and 1906.
My father, unfortunately, met his death in a railway accident in 1905, and the corrections and additions to the last edition, which had been to a certain extent prepared by him, were completed and written by myself, and the work as published then was again reprinted in 1911.
As the original text is now thirty years old, it has seemed better entirely to re-write the whole book rather than make fresh revisions, the more so as the last ten years have seen great advances in the science of Lantern Projection, and especially in the developments of Acetylene and Electric Lighting.
