After being unhaired they must be submitted to complete immersion in the hydrocarbons for at least four hours for the heavy oils, and eight for the light oilsand tar oil; they are after¬ wards well rinsed and finished or dressed in the usual manner. The skins by 5 this process acquire such a decree of suppleness that it will be found practi¬ cable to use for manufacturing gloves skins which prepared by any of the ordinary processes could only be used for making boots and shoes, and consequently their value will be more than quadruple that which it would be if the skins were prepared in the usual manner. As the heavy oils are at the 10 present time much cheaper in the market than the lighter oils, or even than tar oil, the heavy oils are those which should be employed, as far as practicable, in preference to the others, inasmuch as their action is more certain, decided, and energetic in the different processes above mentioned. In witness whereof, I, the said William Edward Newton, have hereunto 15 set my hand and seal, the Thirty-first day of December, in the year of our Lord One thousand eight hundred and sixty-three. W.
