Has heard from G. B. Airy that T. F. Colby has written to Ireland for the compensation bars. An additional assistant has been designated but no appointment made yet. Received a letter from their good friend but does not feel justified in bringing it to the notice of a minister. Admiralty has borrowed Fuller's theodolite (from R.A.S.) and the mural circle should soon arrive. Gives Michael Faraday's analysis of the meteorolite.
