Dr. Jones. 
Mr. Watt, then, that immortal mathematician and mechan- 
ist, ae the kindness to give me a general view of the discove- 
e steam power, and with that impartiality which de- 
notes thé real friend of mankind, he allowed to France and 
to England ‘what they were respectively entitled to claim, 
To France, the famous machine of Dr. Papin, which in the 
year 1698, exhibited the power of steam to procure the dis- 
solution of bones and other substances, and was supplied 
with the first safety valve. But to England he attributed the 
discovery made, at the same period, by Savary, of the ap- 
plication of steam, as a_power to raise water from wells by 
atmospheric pressure. - experiments made on the power 
of steam, under the reign of Charles Hl. by the Marquis of 
Worcester, during his confinement in the tower, as well as 
a very remarkable attempt at an anterior period, under the 
reign of Charles I. to propel vessels by the power of steam, 
were also noticed by Mr. Watt, as having concurred to give 
the idea of the first engine, combining the expansive force of 
steam and atmospheric pressure, which first engine was, I
