Excerpt from Eye Studies: A Series of Lessons on Vision and Visual Tests

That this method will be regarded as an excellence the author believes. Perhaps this is the place to confess that variation from this general method by some recog nized authorities has been the chief secret and source Of awakening our interest in developing optics. A frequent complaint has reached us, that writers treat each topic in a disjointed, fragmentary way, scattering different phases of its treatment through their books so indiscriminately as to make the looking up and gathering together, necessary to secure a completed conception Of the subject, a tedious process. Our treatment takes an entire survey Of each subject in the one lesson assigned it. Whenever two lessons have mutual relations this method, necessarily leads to a measure Of repetition. Apparently the most Of the commendations given our lessons have been prompted because Of the above method in their develop ment. When the mind moves logically, it takes in a subject in all its relations, there is a natural unfolding Of the theme, a progress of thought and breadth Of view, combining unity and comprehensiveness. There.is the absence Of one-sidedness, fragmentariness. All minds are naturally logical, -not that all can develop a subject logically, but that all recognize the value Of logical development. Perceptively, if not constructively, they are logical. Conscious Of his lack of limpid rhetoric and a facile pen, the author may be pardoned the single gratulati'on above indulged and credit to his constructive conception, his methods of classification, the hearty appreciation he has received and the numerous solicita tions that the Eye Studies be published in book form.

We cannot forbear brief reference to encouraging progress in optical literature in the last few years. There was painful need Of it. The great work Of Donders was not written till 1864. Most of the other works mentioned below have been written in the present decade, the chiefest among them within from three to Six years. Considering the importance of the subject this is astonishing. But it is less astonishing than another fact, - the dearth Of exclusively Optical periodicals. To the best of the writer's knowledge and belief he was the editor of the first journal of exclusively Optical character. Its initial number appeared in Detroit for january-february, 1886.
