It was held that this was not anticipated by an English patent granted to one Alexander Parker for treating caoutchouc, for the same purpose, with a bath of coal-tar naphtha and chloride of sul- phur, in the proportion of 40 to 1.

Coal-tar naphtha (called also light- spirits naphtha, crude benzole, and rectified naphtha) is obtained by treating coal with beat, and it was proved that it differs both ...physically and chemically from carbon spirits.
