Bollettino meteorologico ed astronomico del Regio Osservatorio dell'Università di Torino, 1871 (vol. 6)
A meteorological and astronomical bulletin issued in 1871 by the Royal Observatory of the University of Turin, Italy, recording daily observations for public and scientific readers. Its pictures are printed charts of January 1871 weather readings, with stacked line graphs of barometric pressure, thermometric temperature, vapour tension and relative humidity plotted by day against numbered gridlines. A designer might take the dense, rhythmic wave lines and tidy ruled grids as a source for data-visualisation texture or vintage scientific layouts.
