A laboratory course in experimental physics
A university physics laboratory manual by William James Loudon and John Cunningham McLennan, published by Macmillan in New York and London in 1896 for students performing bench experiments. The wood-engraved figures show clamped instruments, barometer tubes, stopcocks, graduated scales and coil-wound armatures in crisp hatched line, with letter keys usable as ready-made technical ornament or diagram components.
