Progress on barometer curves. Invites WB to send report, to be read at B.A.A.S. meeting in July.

Sends missing barometer observations from Montreal, Flushing, and Albany. B.A.A.S meeting postponed.

Received WB's report on barometer observations. Admires perfect finish of work.

Fully examined WB's report [on barometer observations]. Agrees to combine British and Continental observations. Curves clearly show atmospheric processes. Likes WB's suggestion of tracing atmospheric wave beyond 24 hours; will propose this to B.A.A.S. Irregularity of Asiatic and South African data.

Cambridge barometer observations. Postponed WB's detailed report until 1842 B.A.A.S. meeting. This year JH will report generally on atmospheric curves and WB's notes. Hopes WB will attend to give explanations.

Heard of WB's bout with typhus. Interest in atmospheric waves should ensure publication of WB's article in Athenaeum. Will write editor on WB's behalf. Awaits completion of atmospheric curves for B.A.A.S. Congratulations on recently acquired office.
