which remains solid at 100° Fabrenheit. But he had sepa- 
rated the two ee and re-combined them in various 
ways. Without any chemical analysis, he had compared 
the elaine of tallow with the sweat of cattle, and found a 
great resemblance in their sensible qualities; though the 
latter contained a larger proportion of water and of muriate 
of soda.. From these observations he aie that during 
the hot part of the season, when cattle sweat profusely, such 
a large proportion of the elaine ” evacuated through their 
skins, that the stearine is left in a much larger proportion 
than that which is found in their tallow after the sweating 
season has aaa

— If melted ple shoals and anthracite do really 
approximate tow s the character of diamond, we ought, 
to expect that, in ng nies ears of fusion, there would a a 
amination of conducting power, with respect both to heat 
and to electricity. This I find to be the fact. As soon as 
the point of charcoal is fused by the ey the power 
of the instrament is very much impeded by it; but as soon 
as the melted portion is removed, the remaining charcoal 
conducts as well as before; and so on, for any number of 
Soe of the experiment, with the same pieces of char-

ors,as strictly so as the diamond. This fact is very peep 
exhibited, when a point of prepared charcoal, connec 
withthe zinc pole of the deflagrator, is madeto touch a ao- 
bule of melted plumbago, however small, still adhering to 
a parallelopiped of plumbago, in its uataea’ state, screwed 
into the vice connected with the copper pole; not the minu- 
test spark will pass; but if the charcoal — be moved,
