Application. 



By- his own proportion 14,75 lime fhould take up 21,22 of real 

 acid, for as 55:79,14:: 14,75: 21,22 nearly, then 1745,4-21,22 

 = 35 97, confequently the remainder v. z. 2 grs. were water, then 

 the centenary proportion fliould be 



as 38 : 14,75 :: 100 to 38,81 lime 



38 : 21,22 : : 100 to 55^84 real acid 



then the remainder is 5,35 water 



100,00 



Experiment '^d. i Bergm. 135. 



Bergman's felenite is cryftallized and contains fo much water 

 that it is plain he fuppofes it dried by mere expofure to. the heat 

 of the atmofphere. 



according to him 100 grs. contain 46 vitriolic acid 



32 lime 

 22 water 



100 



Hence ift, we have the proportion of felenite dried in 3 dif- 

 ferent degrees of heat, that of ignition, that of the atmofphere, 

 and that between 130* and 170*
