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.
