JH's mother will pay Mr. Beckwith to cover debt of MB's brother Thomas, who now owes Lady Herschel £1035. Comments on Thomas Baldwin's proposal for business partnership with JH and request for loan from JH.
Gratitude to Gioenian Academy of Natural Sciences of Catania [Sicily] for electing JH a corresponding member. [P.S. 1 Oct. 1825:] Reports elevations on Mount Etna measured by JH with mountain barometer in July 1824, with confirmation by Niccolo Cacciatore. [JH's annotations explain sources of errors in elevations.]
Assures SW that slanderous reports regarding SW's nephew James White have not reached JH or Lady Herschel.
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.
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.
Announces 2 June meeting of 'Commissioners for more effectually discovering the Longitude at Sea.' Inquired about 'excise,' but sees no reason to wait for Navy Board to act.
Discusses JH's rent at Devonshire Place.

Missed JH at the R.S.L. meeting. Has some experiments on which he seeks JH's opinion regarding presentation at the Society. Enclosing report.
Presented WR's paper on a new photometer to R.S.L. Discusses how objections may be avoided. Believes [John] Leslie's photometer should be thrown aside.
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.
Will present alterations of WR's paper to R.S.L. [see JH's 1825-1-27]. Asks if he may describe the similarities between WR's photometer and an instrument JH used in Italy and Sicily.
