19. Carburetted eee encased in spheres of Carbonate of Lime. 
—Extract of a letter to the Junior Editor, dated Boston, Sept. 22, 1841. 
__ My dear Sir—A short time since my attention was attracted by a 
few small white particles which had collected on some gas-light burners, 
and which on examination I was much surprised to find were lime. 
The burners were more than a mile from the works, and I was satisfied 
it could have proceeded only from the purifyers, which contain lime. 
Pursuing the enquiry, I have discovered. a great number of hollow 
spherical bodies, formed of carbonate of lime, and filled with carbu- 
retted hydrogen. They are from 7th to =th of an inch in diameter, 
and, the crust or shell being thin, they are easily conveyed, by the 
current of gas flowing through the pipes, even to sg nl in chambers 
more than a mile distant. Yours, truly, Joun. H. Bake.»

Charles C. Rafn, Secretary of the Royal Society of Northern Antiqua- 
ries, to Dr. Jacob Porter, of Plainfield, Massachusetts, dated Copenha- 
gen, May 19, 1840. 
* Are Frode and Semund Frode are the first, we know, who, during 
the latter half of the. eleventh and beginning of the twelfth century, 
exerted themselves for the preservation and promotion of the old Da- 
nish literature. After them, in the subsequent centuries, follow a series 
of meritorious individuals, in whose footsteps we are now treading, ~ 
making strenuous efforts in the same direction, and for the attainment 
of the same end. Through the combined exertions of active men, we 
have: the satisfaction of seeing this noble. literature by degrees awaken 
a greater interest, and acquire more numerous cultivators in both hemi- 
spheres. It rejoices us that you are inclined to take an active shares 
in such exertions.” —_. ak c
