Elementary lessons in electricity & magnetism
A school physics textbook by Silvanus P. Thompson, published by Macmillan in New York and London in 1895 for students beginning electricity and magnetism. Wood-engraved figures show benchtop apparatus — electroscopes, bell jars, brass spheres, protractor scales — often with a shirt-cuffed hand holding a rod, plus line diagrams tracing field lines; useful for engraved hatching, instrument silhouettes and demonstrating-hand motifs.
