Copy letter from Michael Foster, to members of the Delta Committee 'Dear [blank] The specimens of the Delta Borings are at present stored in the rooms of the Royal Society. This is inconvenient. It seems desirable that they should go to the British Museum (Natural History Department). It does not seem worth while to call the Committee for the purpose of deciding this, if the individual members agree. It is also proposed to give Captain Lyons a set of the specimens. I imagine that you will agree to this also? I am, yours faithfully, M. FOSTER Sec. R.S. [Secretary, Royal Society]'. 17 December 1896
