To Bernhard Studer 20 January [1847]
Summary
Much interested in BS’s letter on gneiss ["Remarks on the geological relations of the gneiss of the Alps", Edinburgh New Philos. J. 42 (1847): 186–7].
Sends copy of South America.
Has shown that lamination of metamorphic schists closely allied with cleavage.

To Bernhard Studer 21 March [1847]
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.

Summary
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.
