Laboratory exercises in physics for secondary schools
A laboratory manual of physics experiments by George Ransom Twiss, published by Macmillan in New York and London in 1902 for secondary-school students and their teachers. The line engravings show apparatus in clean perspective—clamps, weights, pulleys, inclined planes, thumbscrews—drawn with open outlines and light hatching, useful as diagrammatic spot art or as parts for mechanical collage.
