Abstract
THIS is really two books, each with its own preface, though the paging is continuous. The second part consists of the laboratory instructions that the author issues to his students as they work through the prescribed course. These instructions are not modified to render them suitable for others than those for whom they were originally intended, and so we are told that “the staff reserves the right to impose fines” for breakages, that the work “confers two credits,” and so on, This is a trivial matter, but when we are repeatedly told to consult the bulletin board, or to apply to the instructor, the difficulty is real; and, seeing that the bulletin board and the instructor are in Wisconsin, and we are in London, these sources of information are impossible for us. The course prescribed is an excellent series of twenty-four experiments in the making of negatives, printing by various processes, spectrum photography, photomicrography, enlarging, the xise of autochrome plates, and, finally, getting the characteristic curve of a plate by means of the Chapman Jones plate tester.
