[Read before the Royal Society of N.S. W., 7 September, 1881.] 
I susmirrep to the Astronomical Section of the Royal Society, at 
their last meeting (August 5), an approximate determination of the 
orbit of the Comet which visited us in May and June last. That 
elements of the great comet of 1807, the longitudes in both 
systems being referred to the mean equinox of 1881-0.

astronomers,
