Reducing Doubt in Industry-Increasing Safety to Mankind IN the whole wide field of Optics no art is more widely useful or more greatly fascinating than that of Photomicrography. We see its record upon the photographic print. Clear and sharp it there stands forth, an image surprising in its clarity and exactitude-and yet it means more than this. Before us it stands a record, enlarged and permanent, of organisms and details too infini tesimal for the unaided eye to fathom. Of all the benefits Industry owes to this optic art-which combines at once the powers of microscope, of camera and of optical projector the manufacturer who deals with raw materials is gratefully aware. To him whose products involve the use of iron, steel, brass and the different metallic alloys those benefits are incalculable indeed. From it he gains a record alike of flaw and strength in his materials; and from it gathers, too, a knowledge, definite and certain, of the struct ural compositions with which he deals. Of like import is it to the worker in textiles, paper, foods and similar products. So stronger bridges, safer rails and steamships, sounder business structures, better clothes and purer food result from these surprising images which, revealed by the microscope, recorded by the photographic camera, illustrate in yet another field of wide and important application how Optics renders its vital service. So, too, does Photomicrography solve for In dustry the problems of efficient production, while granting a greater measure of safety to mankind. BAUSCH & LOMB OPTICAL COMPANY . . ROCHESTER, N. Y.
