Light, photometry and illumination : a thoroughly rev. ed. of ''Electrical illuminating engineering''
A 1912 McGraw-Hill technical textbook by William Edward Barrows, revising his earlier "Electrical Illuminating Engineering" for students and practising illuminating engineers in New York and London. Its plates are line diagrams: fans of candlepower distribution curves, isolux contours over street sections, ray paths through prisms and mirrors, and polar and rectangular graphs numbered along their axes, all printed black on cream.
