BREISLAK, SCIPIONE (1748-1826) , See also:Italian geologist of See also:German parentage, was See also:born at See also:Rome in 1748. He See also:early distinguished himself as See also:professor of mathematical and See also:mechanical See also:philosophy in the See also:college of See also:Ragusa; but after residing there forseveral years he returned to his native See also:city, where he became a professor in the Collegio Nazareno, and began to See also:form the See also:fine mineralogical See also:cabinet in that institution. His leisure was dedicated to See also:geological researches in the papal states. His See also:account of the aluminous See also:district of See also:Tolfa and adjacent hills, published in 1786, gained for him the See also:notice of the See also:king of See also:Naples, who invited him to inspect the, mines and similar See also:works in that See also:kingdom, and appointed him professor of See also:mineralogy to the royal See also:artillery. The vast works for the refining of See also:sulphur in the volcanic district of See also:Solfatara were erected under his direction. He afterwards made many journeys through the See also:ancient See also:Campania to illustrate its See also:geology, and published in 1798 his Topografia fisica della Campania, which contains the results of much accurate observation. Breislak also published an See also:essay on the See also:physical See also:condition of the seven hills of Rome, which he regarded as the remains of a See also:local See also:volcano,—an See also:opinion shown to be erroneous by the later researches of G. B. See also:Brocchi. The See also:political See also:convulsions of See also:Italy in 1799 brought Breislak to See also:Paris, where he remained until 1802, when, being appointed inspector of the See also:saltpetre and See also:powder manufactories near See also:Milan, he removed to that city. The See also:mineral Breislakite was named after him. He died on the 15th of See also:February 1826.

His other publications include:—Introduzione alla geologia (1811, See also:

French ed. 1819); Traite sur la structure exterieure du globe, 3 vols. and See also:atlas (Milan, 1818, 1822); Descrizione geologica della provincia di Milano (1822).
