Of the Properties of the Steam of Water of different degrees 

 of elastic force. 



The mode of obtaining the first five columns is obvious ; and in the fourth and 

 fifth the negative sign indicates that the force of the steam is less than atmospheric 

 pressure, and the numbers show how much less : the sixth column is calculated 

 by art. 89, the seventh by art. 121, and from it the eighth and ninth: the tenth 

 column is calculated by the equation in the note to art. 136, with the allowance for 

 contraction "of the aperture ; and the last column is obtained in the manner shown 

 in the note to art. 190. 



* The usual force of low pressure steam.
