Submarine Photography

M. Louis Boutan has made a study of submarine photography. He has discovered processes that make it possible to secure good negatives at a depth of 150 feet. The same arrangements will serve, no doubt, for much greater depths. Scientific men will use these processes for many researches on the life of submarine' animals that have been impossible. Their applications to certain practical matters are also very important. Submarine divers will find their dangerous and tedious business expedited, and the repair of breakages in flooded mines will be made more easy and safe.
