Then ioo grains muriated lime, weighed red hot, contain nearly 

 50 of lime, 42 of acid and 8 water. 



Bergman agrees with me fo far as ftating the proportion of 

 lime in this fait to be fuperior to that of acid; to loo parts of 

 this fait he affigns 44 of lime and 31 of acid, but the proportion 

 of acid is higher, for to 44 of lime 37 of acid appertains, by the 

 proportion above ftated then that of water is 19. 



Note. His fait was weighed at far a lower temperature than 

 Wenzel's, and hence the quantities but not the proportions in 100 

 grains of it are altered, as it powerfully attrads water.

 Muriated Magnesia. 



The proportions of acid and bafis in this fait are difficultly deter- 

 mined, as it powerfully attrads moifturc and eafily lofes its acid 

 i£ ftrongly heated, and without fuch heat will retain much water. 



In my experiments it appeared that 100 grains mere magncfia 

 took up 21 5,8 of ftandard, or 1 1 1,35 of real marine acid. 



And ioo grains real marine acid take up 89,8 of mere mag- 

 nefia.
