quently that lime must be represented by 35,4^>, and carbonate 
of lime by 63. 
If I would proceed in the series for the purpose of estimat- 
ing the reliance to be placed on preceding analyses, I might 
dissolve 63 of carbonate of lime in muriatic acid, and by eva- 
porating to perfect dryness should obtain about 6^, ^6 mu- 
riate of lime, and by deducting the weight of the lime 354^ 
should learn, by means of the difFerence 34,,!, what is to be 
considered as dry muriatic acid. 
But since lime is now known, by the brilliant discoveries of 
Sir H. Davy, to be a metallic body united with oxygen, this 
salt may also be viewed as a binary compound in a different 
light as oxymuriate of calcium; in which case we must trans- 
fer the weight of 10 oxygen to the muriatic acid, making 4,4,,! 
of oxy muriatic acid combined with 25,46 calcium. Or, lastly, 
if with the same distinguished chemist, we regard it as chlorid 
of calcium, its place in the scale of equivalents is the same 
69,56, and the portion of matter here added to the calcium, 
whether it retain its late name of oxymuriatic acid, or revert 
to its original one of dephlogisticated marine acid, or assume 
its new one of chlorine, will be rightly represented by 44,1, 
which expresses a bare fact without reference to any theory, 
and affords the means of estimating the proportion of this 
constituent in all muriatic compounds, without need of con- 
troversy respecting its simple or compound nature, which may 
* In Dr. Marcet’s experiments on the composition of muriate of lime, referred 
to in his Analysis of the Water of the Dead Sea, 
50,77 carbonate gave 56,1 of muriate of lime, 
and 50,77 : 56,1 : : 63 : 69,6.
