The Hot Blast Patent. This patent expired on the 11th Sept. 
1842 in England, and on the 1st October in Scotland, and has 
proved one of the few which are eminently successful to the in- 
ventor. Besides being of great national benefit, it has realized 
a sum of not less than ^150,000 to the patentees, and has 
placed John Beaumont Neilson high in the ranks of the bene- 
factors of, not his country alone, but of mankind, iron being the 
most useful of the metals, and its cheap production of immense 
importance in arts and manufactures. — Times, Nov. 2^5th, 1842.

lining cavities in a silvery white mica, and sometimes imbedded 
in a dark purple fluor. — [Amer. Journ. of Science.)

series of changeable weather, which terminated in eighteen hours 
heavy rain immediately before the shock was experienced, and at 
the time of the shock, the wind was S.W. with a clear sky. —

An earthquake was felt on the 12th Nov. 1842, at IMontreal, 
Three rivers, the St. Maurice, Torges, and other places. There 
was a sudden sound, a rumbling noise, and an explosion like a 
24-pounder, a violent trembling of the earth, the rocking of 
houses, the cracking of walls, and various other phenomena. But 
little damage was done.^ — -American correspondent of the Times.
