Scientific researches, experimental and theoretical, in electricity, magnetism, galvanism, electro-magnetism, and electro-chemistry
William Sturgeon's 1850 treatise on electricity, magnetism, galvanism and electro-chemistry, published by Thomas Crompton, presents its experimental apparatus in numbered engraved plates for natural philosophers and students. The plates show coils, glass jars, and electromagnets drawn in fine line with lettered figure labels, which a designer might borrow as precise technical diagram motifs for science-themed layouts, borders, or instructional graphics.
