St. Andrews 34 (Adraft: TxU:H/L-0158 & -0145.2; Reel 1054 & C: RS:HS 22.44)
Summary:

R.S.L. will deviate from its intellectual purpose whenever it meddles in practical observations. Proper role for R.S.L. is to suggest goals and methods and to reward discoveries. Recommends discontinuing meteorological observations at Somerset House; other stations now provide better data. If R.S.L. insists on establishing a meteorological register, JH suggests one like that of J. F. Daniell.
