Informs TM that JH's 20-ft. telescope is fully in operation; invites TM to come and observe with it.
Points out errors in his own chronometer. Gives thermometer and barometer readings. The work of the bricklayers is very slow. Is obliged for the drawing of the nebula.
The chronometer can remain at the Grove for the time being; it seems to preserve a more uniform rate than the transit clock.
Invites Herschels and Dr. Duncan Stewart to dine with TM. Would like to compare their barometers. Would like also to show JH his own investigation on the mural circle. Has procured a chameleon.
