Letter from Edgar A[lbert] Smith, British Museum (Natural History), Cromwell Road, London, to Henry B[owman] Brady Has examined Brady's sections but could not find any indication of the presence of any volcanic material, 'unless it be in section A which encloses some very minute grains of an opaque, black, lustrous mineral which may be magnetite or perhaps ilmenite', substances common in igneous rocks of all ages. Gives further details of the minerals found in the sections. 1 December 1887
