About observing stars with the transit circle, and timing the annulus [of an eclipse?].
Was too cloudy to observe the eclipse; very worried about the health of Thomas Maclear.
Asks GA for details about the scientific support provided by Hugh Percy; also asks about the availability of star charts on the Berlin Academy scheme.
