Agrees that Kew Observatory should remain open. Will urge B.A.A.S. to continue observations. Admiralty Manual going slowly. WB may use Admiralty's printer for WB's separate article. Did not tell Lord [Auckland, i.e., George Eden] of WB's offer to go to New Zealand.

Will forward WB's report on Kew Observatory to [John] Taylor. Praises WB's thoroughly inductive discussion of atmospheric electricity.

Certain that JH did not receive WB's 'Sheet of Curves.' They may be in Edward Sabine's or WB's own possession.

Returns [WB's] paper on the zodiacal light. Notes error and offers JH's ideas about light's source.

Attests to W. R. Birt's scientific capabilities and dependability. Regrets Birt's departure from previous position.

Must report progress of meteorological reductions to B.A.A.S. Send specimen of 'Curves' before first week in September. Gives latitudes and longitudes for North American stations.

Explains 'discordances' as contraction of damp paper. Use 'Engraved Squares' to avoid this error. Possible error in barometer observations from Montreal. Diurnal 'undulation' appearing in data. American observations arrived, may fill 'missing intervals.' Keep record of expenses incurred. Postscript on color variation in stars.

Received WB's packet. Will send sheets tomorrow. Needs all 'Curves and data' before end of March for final report to B.A.A.S. JH's nerves 'shattered with night work.'

Omitted important detail yesterday in JH's description of self-compensating barometer. Columns must be variable, not constant.

[WB's] sheets [of barometer observations] are well done. Sends European latitudes and longitudes. Will send 'Engraved Squares' soon. Notes errors in observations.

Admiralty Manual must be succinct. WB's specialized notes [on atmospheric waves] are too extensive.

Returned [WB's] manuscript with Admiralty notes last week. Concerned, because postal service lost C. R. Darwin's manuscript when JH returned it.
