Bollettino dell'Osservatorio della Regia Università di Torino, 1887 (vol. 22)
This is a 1887 volume of meteorological bulletins from the Royal University of Turin's observatory, produced by the Osservatorio astronomico di Torino for scholars and observers. The pictures are printed chart plates of monthly weather records, each with four stacked line graphs for barometric pressure, temperature, vapour tension and relative humidity across the days of the month. A designer might take the plain grid layouts, fine ruled lines and hand-lettered Italian headings as a model for scientific data charts.
