BROCCHI, GIOVANNI BATTISTA (1772-1826) , See also:Italian mineralogist and geologist, was See also:born at See also:Bassano on the 18th of See also:February 1772. He studied at the university of See also:Pisa, where his See also:attention was turned to See also:mineralogy and See also:botany. In 1802 he was appointed See also:professor of botany in the new See also:lyceum of See also:Brescia; but he more especially devoted himself to See also:geological researches in the adjacent districts. The fruits of these labours appeared in different publications, particularly in his Trattato mineralogico e chemico sulle miniere di Ferro del dipartimento del Mella (18o8)—treatise on the See also:iron mines of Mella. These researches procured him the See also:office of inspector of mines in the recently established See also:kingdom of See also:Italy, and enabled him to extend his investigations over See also:great See also:part of the See also:country. In 1811 he produced a valuable See also:essay entitled Memoria mineralogica See also:sulla See also:Valle di Fassa in Tirolo; but his most important See also:work is the Conchiologia fossile subapennina See also:con osservazioni geologiche sugli Apennini, e sul suolo adiacente (2 vols., 4to, See also:Milan, 1814), containing accurate details of the structure of the Apennine range, and an See also:account of the fossils of the Italian See also:Tertiary strata compared with existing See also:species. These subjects were further illustrated by his geognostic See also:map, and his Catalogo ragionato di una raccolta di rocce, disposto con ordine geografico, per servire alla geognosia dell' Italia (Milan, 1817). His work Dello stato fisico del suolo di See also:Roma (182o), with its accompanying map, is likewise noteworthy. In it he corrected the erroneous views of See also:Breislak, who conceived that See also:Rome occupies the site of a See also:volcano, to which he ascribed the volcanic materials that See also:cover the seven hills. Brocchi pointed out that these materials were derived either from Mont Albano, an See also:extinct volcano, 12 M. from the See also:city, or from Mont Cimini, still farther to the See also:north. Several papers by him, on mineralogical subjects, appeared in the Biblioteca Italiana from 1816 to 1823. In the latter See also:year Brocchi sailed for See also:Egypt, in See also:order to explore the See also:geology of that country and See also:report on its See also:mineral resources.

Every facility was granted by Mehemet See also:

Ali, who in 1825 appointed him one of a See also:commission to examine the See also:district of Sennaar; but Brocchi, unfortunately for See also:science, See also:fell a victim to the See also:climate, and died at See also:Khartum on the 25th of See also:September 1826.
