The analyses which I have made accord as well as can be 
expected with those results. They result as follows:

This point established, I pass immediately to the products 
derived from the action of different bodies upon salacin, and in 
the first rank I place those substances which are always form- 
ed whenever salacin is submitted to the influence of an oxida- 
dating body, under particular conditions. Their history is to- 
tally independent of that of salacin. 
At the end of this paper I shall not fail to state some expe- 
riments, by the aid of which I believe that the formula and 
equivalent weight of salacin may be established. 
The action of oxidating bodies. 
The action which some oxidating bodies exercise upon sala- 
cin is, without doubt, the most remarkable which chemistry of- 
fers. The examination of the products of this reaction has led 
to very unexpected results. 
We know from the experiments of Dcebereiner upon the 
production of formic acids, that salacin, as well as many other 
organic bodies, yields formic acid. When treated with peroxide 
of manganese and diluted sulphuric acid, I have also obtained 
the same result, but on using a mixture of bichromate of po- 
tassa and sulphuric acid as the oxidating agent, besides obtain- 
ing carbonic and formic acid, as in the preceding case, another 
very remarkable substance was produced, possessing very great
