an account of it before he fainted. I immediately applied 
the ammonia to the parts that had been stung, his legs, arms 
and breast. He directly recovered from his ‘faintness, and 
experienced no pain or other inconvenience afterwards. 
It is several years since I first used the aqua ammoniz, to

In a recent examination of th me seme supposed to to 
protoxide of mercury, my attention was int to the os 
ject of the atomic weight of mercury, and upon applying to 
some of its combinations, the generally scar theory, that 
binary compounds are more difficult of decomposition than 
ternary, I have been led to the conclusion, that its equiva- 
lent number has been mis stated by chemical writers, 
The protosulphuret and protochloride, are both more ea- 
sily decomposed than the compounds containing double the 
proportion of their respective electro ——- The only

I have very frequently decomposed several of the proto- 
salts of mercury with alkalies, and the resulting powder has 
uniformly contained metallic globules, either visible to the
