Mr. Giddy has favoured me with an account.of some 

 very accurate observations on the quantity of water em- 

 ployed for supplying a steam engine, by which it appears, 

 that the specific gravity of steam under a pressure of about 

 30. is nearly .5^, or a little more than one third of that of 

 air; which agrees very well with Desaguliers's experiments. 



Professor Robison observes, that, in his experiments, the 

 addition of 30° to the temperature, in most cases, nearly 

 doubled the elasticity both of steam and of the vapour of
