Upon returning to the observatory, hefixes the diagram with gum-lac dissolved in alcohol,makes a detailed report upon the meteorological con-ditions previous to and during the ascent, and sendsthe whole to Prof. Hergasell, superintendent of theMeteorological Institute of Strasburg. At Strasburgthe various diagrams obtained at the different aeronau-tic stations are studied and the results thereof co-ordinated. The material is afterward published in aspecial organ entitled Veroffentl
