will be equally a great distance for projectors whose diameters so far do not exceed 1*5 m. Now it is a fact of experience, the theory of which will be given elsewhere, that, after a certain distance the illumination measured in the axis of a pencil by the dbserver varies in the ratio of the inverse square of the distance to the surface of the projector. There is nothing to hinder the application to that secondary source of the definition applicable to all sources of great dimenr sions, and to ...say with all professional engineers i^^The luminous intensity of an optical instrn' ment at a great distance in the axis of the pencil is the constant quantity to which the product of the intensity of illumination by the square of the distance rapidly attains P ^l^ E (i) that is to say, consequently, the intensity oj a naked light which would produce the same illumination at the same distance. In France, to better characterize what is meant by an intensity at a great distance, the expres* sion luminous power of an instrument strongly advocated by M.
