Tho absolute stability of this nitro-celluloae. of such importance to explosive bodies, is thus ex ; plained.

This silica acts in straw nitro-cellu-I lose in tho same way as in dynamite, fixing the nitro glycerine, and giving a stability to this substance, which it does not possess when it is I alone.
