Item 36 - Letter from John Herschel

JH would like to know whether WW will authorise him to pay for the two actimometers, for a vertical force magnetometer and for a bifilar magnetow for the [Breslau?] observatory. JH doubts whether they should purchase Osler's anemometer since he doubts whether their power extends to the ordering of meteorological instruments, and unlike the actimometers this is a very expensive instrument. Further 'they cannot be constructed abroad having never been described'. If WW and Peacock agree on the grant can they tell [Edward] Sabine. There will be no grant for the Hammerfist as was originally thought.
