** The excavations at Pompeia are prosecuted after a certain 
plan, so as to go round the whole town, which, when cleared 
from the ashes that cover it, will probably become one on the 
most remarkable monument of antiquity.’ 
An improved Printing-machine just completed by Mr. Kenig, 
the inventor of that which has been employed upwards of a 
twelvemonth in printing the Times and Evening Mail news- 
papers, was tried for the first time on Wednesday, Feb. 28th, at 
‘the manufactory, in the presence a on Imperial Highnesses 
the Archdukes JoHn and Lewis. r. Keenig has now made 
some very material improvements in: Wis invention, by which its 
advantages are greatly increased.

the night was very severe; the thermometer being about fen 
degrees of Fahrenheit. On the 8th it scareely rose above that 
degree all day, and at midnight was 6°; at three o’clock im the 
morning of the 9th, 5°; and at sunrise, 4°. In other parts of 
the parish of Hackney it is said to have been two degrees lower, 
At Walthamstow, about three the same morning, it was 12°, 
The same night it was about 24° at Clapton. On the 10th it 
rose several degrees, and the ordinary cold of winter returned. 
Nothing remarkable either in the height or variation of the ba- 
rometer, or of any other meterevlogical instrument, occurred ; 
the sky was, during the cold, almost entirely free from clouds.
