From 1822 to 1825 the surveyors were studying field geology iji Kiigland. In 1825 tlio work was commenced in France, Do Beaumont taking the cast, Dufrciioy tho west. There were two assistants, and the survey was completed in 1830. The map, ' Carte Gi'ologiqno do la Franco, ' is in (i shoots, scale 1 : 500, 000. It was published in 1810-42 ; the two volumes of ' Kxplica- tion ' in 1841 and 1818. A reduction of this map ('Tableau d'Assemblage'), scale 1 : 2, 000, 000, was published in 1841.

A Geological ^lap of Franco in 48 sheets, scale 1 ; 500, 000, is in preparation by C. Vasseur and L. Caroz.. Italy. Reale Comitafo Geologico d'Italia (Home).' This survey was commenced in 18G8, when tho capital was Florence. It was directed by a committee of Professors at Universities and Engineers of Mines. In 1873, when the chief office and place of publica- tion were transferred to Rome, the staflf was reorganised; tho Comitalo (with Professor Meneghini as president) retained mainly a consulting power, the real chief of the survey being F.

The systematic and detailed investigation of the country dates from 1877, and was commenced in S
