When freshly prepared, well washed, and still moist fulminate of 
mercury is boiled for a quarier of an hour in a glass flask with a very 
dilute solution of an alkaline chlorid, the fulminate is completely dis- 
solved. Ina short time, decomposition commences and oxyd of mercury 
Separates with a bright yellow color. The clear solution is to be 
filtered and a solution of sal-ammoniac added which throws down the 
remaining mercury as white precipitate. The solution after filtration 
and concentration gives crystals of the fulminate of the alkali the 
chlorid of which was employed. ‘T'he author represents the reactions 
In these cases by the two following equations.
