Comparison of the Blowpipe of Hare and Brook. 89 
Although the experiments of Mr. Silliman date in 1812, 
we have thought that they ought to be known upon our con- 
tinent. They demonstrate, on the one hand, that Mr. Clark 
has been anticipated in Ameuica, with respect to the fusion 
of bodies in the flame of hydrogen and oxigen ;—and on the 
other, that the blow-pipe of Hare gives results almost per- 
ies identical with those of Broo kK.
