then evaporated very slowly, and sublimed as above. The 
calomel was totally converted into corrosive sublimate, and 
weighed 113. But 113 of corrosive sublimate contain 20,3 of 
muriatic acid, of which, 11,5 were originally in the calomel. 
The total addition of weight was 1 3. But the quantity of acid 
in these 13, amounts to 20,3 — 11,5= 8,8. Therefore, 13 — 8,8 
= 4,2, remain for that part of the additional weight which is 
oxygen. On the other hand, 100 of calomel contain the same- 
quantity of mercury as 113 of corrosive sublimate, == 79. These 
79, with 11,5 of acid, are equal to 90,5, and leave 9,5 for the 
quantity of oxygen contained in calomel. It would appear, from 
these experiments, that corrosive sublimate contains 6,5 per 
cent, more acid, and but 2,8 per cent, more oxygen, than calomel. 
But this quantity of oxygen is combined with a much greater 
proportion of mercury ; and forms an oxide of a very different 
degree of oxidizement. For, 88,5 : 9,5 : : 100 : 10,7. There- 
fore, we may establish the following comparative table.
