After the severe rain storm of last evening a

nucleus OF which was larger than, and very nearly
as bright as, star OF the first magnitude while
the tail stretched over an arc of at least eighty
degrees, sweeping upwards from an altitude Of six
or eight degrees above the horizon to the milky
way. In general appearance this comet reminded
the observers of the great comet of 1853 but the
suddenness of its approach, and enormous length
OF taii when hrSt seen, are perhaps unparalleled
Editor Sdr:-l watched the comet between half

head appeared to be near the boundary OF the con-
stellations Lynx and Ursa Major, not far from the
mead OF the latter. About quarter before two

stellsrions Urse Minoris and Hercules, and nearly
reached the milky way, passing )me distance be-

less than $50, and its average width was nearly so

The comet was distinctly visible in the heavens
last night. 1t passed over the city in a northeast
ery direction, and in the forepart of the night was
very brilliant, although the tail did not appear to
be anything like as long the night previous.
