Still anxious to become a fellow of the R.S.L. Thanks JH for offer. Would like to be elected before end of present session.
Thanks JH for introducing WR's paper on photometer to R.S.L. council. Sends drawing of instrument and alterations to WR's paper that resulted from improvements in instrument.
Suggested improvements to John Leslie's photometer.
Pleased JH liked his paper on differential photometer. Discusses apparatus for experiments on light. Describes some papers he has written and some he is writing.
Not upset that JH withdrew WR's paper on photometer from R.S.L. Sent similar paper to David Brewster's [Edinburgh Journal of Science] with note on JH's method for finding relative heating power of solar rays. Wants to dedicate WR's book on light and heat to JH.
