Mirrors, Prisms and Lenses. A text book of geometrical optics

Historical Significance: This is an early student text book on geometrical optics although it is not clear to which kind of student it is directed. The author describes it as an abridgement of his book 'The principles and methods of Geometrical Optics' and it includes chapters on astigmatic and toric lenses and the optical system of the eye so it may be directed to optometry and ophthalmology students. James P. C. Southall (1871- ?) was a physicist with a special interest in optics. He taught physics at a number of USA universities before joining Columbia University in 1914, where he served until his retirement in 1940. His specialties were geometrical optics and physiological optics. He wrote Principles of Geometrical Optics in 1910 and Mirrors, Prisms and Lenses (1918, rev. eds. 1923, 1934). He is probably best known as editor of the American English language edition of Helmholtz's Physiological Optics published in 3 volumes 1924-25. Cat No 84. 85, 86. He also wrote Introduction to Physiological Optics (1941). He wrote many papers, a number of which appeared in JOSA, on optical illusions and geometrical optics. He served as president of the Optical Society of America in 1921.
