[Responding to JF's 1849-11-23], JH cautiously discusses various considerations bearing on the idea of sending an astronomer and a large reflecting telescope to the Cape.
Protesting about the refusal of the Royal Society of Edinburgh to publish Thomas Brisbane's magnetic observations; hopes it will be reconsidered. Thinks JF's theory on glaciers has good points, but comments on some of its shortcomings.
Asks for details of several actinometers.
Agrees that it would be desirable to make further observations at the Cape, but foresees difficulties, especially liaison with the Astronomer Royal at the Cape.
