Letters from Bosquet, Joseph to Charles Lyell, 5 August 1850
Summarised by Lyell as 'Bosquet, Maestricht [sic Maastricht] tubes in chalk'. Included is a small envelope containing a tiny packet of pieces of clay - found in thin layers on the walls of the vertical geological tubes of the mountains of St Pierre and in piles in the horizontal and iregular pipes of the same mountains.
