Opening the Shortest Pathway to the Brain IT is the prolonged dusk of Arctic night one hundred miles above the Circle-the ther mometer far below zero and snow piled moun tains high. A crowd of unlearned but eager Lapps, too numerous for the small mission chapel nearby, are assembled in the open air on skis and snowshoes - their eyes centered on a crudely erected screen of snow. Across this screen, as white as Nature can make it, flashes a succession of vivid pictures -Japan, China, Korea, tropical India, all im aged on that Arctic background-pictures of climes and peoples that benighted audience had never dreamed of. And the source ? A simple but efficient little stereopticon, the Balopticon, mounted on a rough table in the snow and covered with a heavy, protecting blanket, that its lenses may not break in the frigid atmosphere. This true incident is perhaps unusual, but no more significant than countless other instan ces of Balopticon service. Optical projection has broken down the travel barriers to a know- ledge of the earth. Photography and projec tion co-operating bring the world to our feet, for whatever can be photographed anywhere can be projected in life-like reproductions any where else. And so in church and mission, school and college, lecture hall and home, wherever peo ple of any race or creed gather together, the Balopticon has made its enlightening way, adding to the sum total of human knowledge as no other agency can. For the eye is the gateway of the shortest nerve path to the brain. What the eye sees, the brain compre hends quickest and remembers longest. In its development of the Balopticon to represent the most complete and efficient line of projection apparatus obtainable, the Bausch & Lomb Optical Company has but further enriched its seventy years of service of supplying practically every form of lens or optical instrument that humanity needs in its search for truth and knowledge Writefor Special Balopticon Circularor Literatureon Other Lines.
