an extent of several square feet, and yet the

that small cube of gold, whose size is the

Mr.. Hcaumer also shows that, in the

one and half inches in diameter, is

In rcgar,l to the whole amount Of gold

@he Cu1oric Notor.-The Caloric Motor,
though found inadequate to the purposes
for which il was originally applied, is
taking rank among the important con
