Bollettino dell'Osservatorio della Regia Università di Torino, 1876 (vol. 11)
This is a Turin university observatory bulletin of meteorological and astronomical observations, issued in 1876 by the Osservatorio astronomico di Torino for scholars and observers. Its pictures are plain printed tables of barometric, thermometric, vapour tension and humidity readings, plus a page of hand-ruled line graphs of daily weather readings for January 1876, showing dense, precise data grids a designer could borrow for technical layouts.
