5. M, de Collegno on the Soulevements of the Hills of Superga. — At a re- 

 cent meeting of the French Academy of Sciences, an Essay was presented 

 by M, H. de Collegno on the geological constitution of the hills of Superga, 

 near Turin. The following are the conclusions deduced by the author from 

 his investigations, and which, while they confirm the observations made 

 many years ago on this well known locality by M. A. Brongniart,at the same 

 time indicate some interesting results obtained by M. de Callegno, con- 

 nected with M. Elie de Beaumount's views on Soulevements. 1. The hills 

 of Superga are composed of beds belonging to three different formations, 

 viz. the upper chalk, the middle tertiary formation, and the upper ter- 

 tiary formation. 2. The present relief oi the surface of these hills results 

 from three distinct movements, which have taken place each at the ter- 

 mination of one of these periods and at the commencement of another. 

 3. The relative age of these " soulevements," although it is not proved to 

 us by phenomena so well marked as those pointed out by Beaumount in 

 great chains of mountains, is nevertheless well determined by the dis- 

 cordant arrangement of the beds of the different formations. The three dis- 

 locations observable in the hills of Superga correspond to the soulevement 

 of the three chains of mountains which divide or surround Italy, viz. the 

 great systems of the Apennines, the Western Alps, and the Eastern Alps. 



6. On the Presence of Cobalt and other metals in the Upper Sandstones of 

 the Tertiary Formations of Paris. — At the meeting of the Academy 

 of Sciences of the 29th February, M. Alexander Brongniart commu- 

 nicated a very interesting discovery recently made by the Duke of 

 Luynes, who has detected the presence of cobalt in the proportion of at 

 least one per cent, of manganese, and of traces of copper and arsenic, in 

 the ferruginous sandstone of the abandoned quarry of Saint-Clair, near
