Summary:

Sends copy of South America.

Will consult BS’s article in the Bulletin.

Recommends article by Daniel Sharpe ["On slaty cleavage", J. Geol. Soc. Lond. 3 (1847): 74–105].

Cites his description of thin laminae in volcanic rocks in Volcanic islands. Suggests similar process may have affected metamorphic schists.

Thanks him for offer of his book [Lehrbuch der physikalischen Geographie und Geologie (1844–7)]. Since he reads German poorly, BS should send book only if short and inexpensive.

Glad BS intends to visit England. Fears there will be few geologists in London in August. Would be truly glad to see BS at Down, but cannot offer much geological information respecting England.
