A glance through the A. P.8. programme for the session 1904-05 shows a most interesting. and well-thought-out sories of lectures, and one that should eminently ai to such & cosmopolitan body of photographers as the possonsos.

The components of a stand camera were then troated: the rising and falling front and or aky; the reversing back, by which jing-back for cutting out foreground perpendicular or horizontal pictures could be obtained without moving the camera; and special stress was laid on the necessity of obtaining a firm tripod—a require-mont often neglected.

Its improvement was then traced; first it was made achromatic by cementing to-gother lenses of different forms and different kinds of glass, chromatic aberration being removed and the various light raysiithat naturally have different foci being it together on the plate. Lenses'of this kind, in which the visible image and the photographic image coin- Band. cide are called achromatic lenses. The next step in the history of lens-making was the correction of astigmatism— defects:, of definition or detail—by the which will be brief The per- though imposing, it is hoped that H.R.H.
