Hydraulic power and hydraulic machinery
A late nineteenth-century engineering textbook on hydraulic power and machinery, written by Henry Robinson and published in 1887 by Ch. Griffin & Co., aimed at engineers and students. Its pictures are measured technical plates in black line: plan and elevation drawings, sectional views of cylinders and valves, and layouts of a swing bridge mechanism, with figure numbers and lettered parts. A designer could take the disciplined hierarchy of labelled plates, the clean cross-hatching of cut sections, and the grid-like arrangement of multiple views on one page.
