The gentleman CONNIE need hislecture by stating
that at the beginning Of the last century, was en-
tirely owing to the enquiries and study OF black
smith and glazier, that the discovery OF an at
mospheric engine, the original OF the present steam
engine, was made known to this country =
The atmospheric engine was found to be
too expensive for ordinary purposes, and i was
laid aside Some time utter tins mat small f s mo
land was sent to Watt, who then carried on the
business of mathematical instrument maker, to
be repaired This person being Of very ingenious





article before him, and directed his attention to
medy them. and the result was the introduction OF
the condensing engine at present in use, about the
year 1854. The principles OF this engine were well
known; its power was caused by the swelling OF
water when heated into steam; for instance, one
pint of water would produce eighteen times its


bulk IN IN
high. Very few Of the great inventions and disco.
veries Of the last century were made by educated
or scientific persons. One of the most remarkable

the decomposition was fully ascertained. The
lecturer then proceeded to take notice Of the far

weight of the globe, and showed by what means
this was ascertained, both by that great philoso-
/ pher and DR. Maskalon, about the same period. He

truly valuable, at the same time very amusing ;
