7. Argentiferous Galena, from the Bor Khamti country, on the sources of the 
Trawadi river. 
A small specimen of this ore, received from Mr. Brucs of Sadiya, in 
Asam, was found to contain one-fifth per cent. of silver: or after 
expelling the sulphur the lead would contain one-fourth per cent. This 
would hardly pay the expence of extraction, but the specimen was too 
small to give a fair average. The ore is however very valuable for the 
lead alone, yielding from 60 to 70 per cent. of that metal. 
At Brahmakund, in Asam, from Mr. Bruce’s specimens, occurs a very 
fine white porcelain clay, which mightbe turned to use were there 
any demand for fine pottery in India, and were the locality a little 
more accessible. 
IX.—Earthquake of the 26th August. 
The daily papers have published notices of this phenomenon, as observed at a 
great many places in the interior of India, with more or less detail, from which the 
following general facts may be gathered :— 
The direction of the vibration was from north-east to south-west : there were three 
principal shocks ; the first about half past six Pp. m. the second at half past eleven; 
and the third or most severe shock, at about five minutes to twelve (Calcutta time). 
In the places where it was most felt slight and continued vibrations seem to have 
been experienced for the whole of the day following. As the time of the second 
vibration was accurately noted in Calcutta by the stopping of an astronomical clock, 
we may assume it as the best point of comparison with the times noted at other 
distant points. Applying the difference of longitude, a few of them may be thus 
classed.

At Monghyr, Rungpdr, Mozufferpar, Mallai, and other places within the direct 
line of influence, many houses were destroyed or injured, and the alarm was great. 
At Katmanda, however, the following extract of a letter from Dr. A. CAMPBELL, 
dated the 28th inst. willshew that the consequences were more serious, and judging 
from the course of the phenomenon we may reasonably fear some dreadful catas-. 
trophe towards Lassa on the north of the great Himalayan range. 
“On the evening of the 26th, about 6 o’clock, the valley and neighbouring hills 
were visited by a severe shock of an earthquake : it lasted about 40 seconds, and 
during its continuance, there was a distinctly audible noise as of ordnance passing 
rapidly over a drawbridge. lt seemed to me to come from the east, and I felt. that 
it was travelling with the speed of lightning towards the west, and just under my 
feet: the houses shook most violently, and trees, shrubs, and the smallest plants were.
