The son of a Turin lawyer, Bartolomeo Gastaldi (1818–79) initially followed in his father's footsteps but then abandoned the law to pursue his passion for geology and palaeontology. Later one of the founders of the Italian Alpine Club, Gastaldi was especially interested in the geology and glaciology of the Alps in his native Piedmont. The mineral gastaldite is named after him. This work, first published in Italian in 1862, is reissued here in the 1865 English translation prepared by Charles Harcourt Chambers (1826–76) for the Anthropological Society of London. Its importance lies in the meticulous descriptions, by Gastaldi and others, of the human remains and artefacts discovered at Stone Age and Bronze Age settlements on the site of lakes and peat bogs to the south of the Alps. Featuring engraved illustrations throughout, the work also includes Gastaldi's summary of discoveries since his book's first appearance.
