10° 17™ 538, remaining fixed for a few moments; at 10" 18™ 12° 
this resolved itself into several bright streamers. I was un- 
able, after this period, to fix upon any sufficiently marked 
appearances to admit of being noted down; the Aurora, how- 
ever, continued for some time longer, till gradually obscured 
by a thick fog which came on at this time. Throughout 
the whole period, the dark part, through which I observed 
stars of the fifth magnitude, was remarkably well defined, 
presenting at times the appearance of a mountain range 
seen at a distance. 
“‘T have offered this very imperfect sketch, in the hope that 
this fine Aurora has not escaped the notice of more accurate 
and better prepared observers; for, if we were supplied 
with a sufficient number even of such rough outlines as the 
preceding, we should be better enabled to answer a question 
very important to the subject, namely—whether different 
observers see the same Aurora at the same tiie ?” 
Dr. Robinson presented a specimen of Meteor Paper, 
similar to that of Carolath, which he had received from the 
Countess of Caledon, with a notice of the circumstances of 
its formation. It was found, last Spring, covering a consi- 
derable tract of meadow land, the property of Lord Radnor, 
in Gloucestershire. The tract of country between Les- 
blade and Farringdon is flooded by the Isis every Spring, 
but not more than usually this season. When the waters 
subsided, the surface of the ground was covered with this 
substance to such an extent as to make its removal and de- 
struction necessary to permit the growth of the grass; some 
of the pieces covering ten and twelve acres in continuous and 
unbroken sheets. Nothing of the kind had been noticed be- 
fore by the oldest farmers. Portions of it were found on land 
which had not been under water. It is denser than any which 
Dr. Robinson had seen, and contains a larger proportion of 
the shields of Infusoria; but the tissue is composed chiefly 
of the conferva rivularis.
