MR. RUMKER’S OBSERVATIONS 
5*2 
Tice Moon. 
The Moon’s orbit, during the intervals between her transits over the meri- 
dians of the Observatories at Paramatta and in Europe, is sufficiently known 
to deduce her Parallax from the following South Polar Distances observed at 
Paramatta. These South Polar Distances answer to the culminations of the 
Moon’s centre, and are different from the times for which the Moon’s right 
ascensions are given in page 28, which correspond to the transit of the first 
or second limb, and must be reduced to the former, by applying the time in 
which the Moon’s semidiameter passes the meridian in apparent solar time. 
The refraction has been applied, but semidiameter and parallax have not.
