twelve weeks, discovered on their land, at a distance of about half a 
mile from this, another bed of exceeding richness, yielding, as Mr. 
Townsend informed me, about seventy five per cent. of pure ore. 
It was discovered by the aid of a compass, the needle of which struck 
upon the dial on being brought over the ground. ‘The ore is a fria- 
ble, strongly magnetic oxide ; the particles when knocked off adher- 
ing to the point of the pickaxe. There is no overlying stratum of 
rock, nor any one contiguous, as far as the excavation has been made, 
which is to the depth of six or eight feet. It appears to be one great 
bed of solid and very pure ore. 
22. Hydrophobia.—We are indebted to a highly valued medical 
friend, for the following interesting communication. The importance 
of the subject on which it treats, will, no doubt, obtain for it an ex- 
tensive circulation. The writer is a man of science and worthy of 
every confidence.—Ed. U. S. Tel. 
_ At the present moment our fellow citizens are considerably excit- 
ed by the fear of mad dogs, by whom at least two children, in this 
city have, within a few days, been bitten. The! horrible nature of 
the disease consequent to the bite—a disease so utterly beyond the 
reach of medical aid, renders it the imperious duty of every one to 
communicate to the public any thing he may know tending to mitigate 
or prevent the awful issue. 
By the late foreign medical Journals we learn that M. Coster, 2 
French surgeon of great eminence, has devoted his attention to the 
subject of animal poisons. He has discovered that chlorine has the 
wonderful power of decomposing and destroying the poison of the 
most deadly, 
~ The saliva of the mad dog, has the property, when inserted under 
the skin, of communicating hydrophobia to other animals, and to 
man. M. Coster has been able, by the use of chlorine, to decom- 
pose this deadly poison, and render it harmless, preventing the ap- 
proach of hydrophobia in animals bitten by dogs decidedly rabid.— 
there can be no doubt of the accuracy of the experiment on which 
this statement is predicated. 
From this the most important practical results follow : : 
: Make a strong wash by dissolving two table spoonfuls of the chlo- 
Het of lime in half a pint of water, and instantly and repeatedly 
‘the part len. The poison will in this way be
