Summary:

Thanks for the interesting account of the star whose variability has now been established. Used the 3 1/2 foot last night and definition was good. Returns JH's letter to [James?] Dunlop and thinks there should be no offense taken. Opening for the Zenith is being enlarged. Measured JH's azimuth East and West yesterday.

Summary:

Gives latitude of 'this observatory' used in reduction of 'Comet stars.' Will accept systematic correction in all data to compensate for differences between TM's and Thomas Henderson's data. Instruments are erratic since telescope was moved. Using transit instrument only for sun, planets, and [reduction of Thomas] Brisbane's stars.
