Practical X ray work
A technical manual on X-ray apparatus and radiographic technique by Frank Thornton Addyman, published in London by Scott, Greenwood & Co. in 1901 for physicians, electricians and laboratory workers. The 46 figures are line diagrams of vacuum tubes, induction coils, geared stands and lettered schematics, drawn in thin outline with hatched shading — useful for apparatus silhouettes, keyed labels and early laboratory hardware.
