    Morrisons Processes for Preserving Animal and Vegetable Substances, the breadth of the washer. The lute may be composed of any materials which form an air tight paste; white of egg, mixed with ground rice, or a mixture of one third tallow and two thirds rosin, answer well. In forming the bungs and cork, it is of advantage to moisten the bladder with white of egg 5 where the button of the tube is to come in contact with it, and in corking to moisten the edge of the bung or cork and the mouth of the vessel with the same substance. The cape for the vessels may be of cast iron, with a cushion at the bottom of felt or other soft substance. Let there be openings in the side of the iron tube, upon a level with the top and bottom of the reservoir, 10 and the bottom of the filler, to allow the air to escape and the liquor to pass, and let the tube itself project beyond the top of the filler to receive the pin. The bladder, previous to being applied to the cock or vessel, to be steeped for twenty-four hours in a mixture of shumac, animal charcoal, and water. 15 And I declare my second Invention to consist in the enclosing food in vessels which, previous to and in the process of cooking, are rendered perfectly air tight by means of a cork or bung prepared as follows :—Cut bungs or corks in the usual way, and coat the under part and sides with prepared bladder, as before directed; apply the cork to the mouth of the vessel, and by means of 20 a screw press force it a fourth part of an inch below the le\el of the lip of the vessel; cover the cork with, such a lute as will, when dry, adhere to the cork in a solid mass ; cover with bladder the mouth of the vessel, and bind the bladder firmly round its neck, and place upon the mouth of the vessel a cape having a cushion of soft laid hemp, or other material calculated to make a steam tight 25 joint; put^he vessel into a press, and screw the cape so firmly down as to prevent the communication of steam or water with the bladder; place the whole in a steam or water bath ’till the contents of the jar are fully cooked, and when removed from the bath and perfectly cool, withdraw the vessel from the press, and the manufacture is completed. A lute composed of one third 30 tallow and two thirds rosin answers well. A Drawing illustrative of the de¬ scription herein contained accompanies this Specification, and is subscribed by me as relative hereto. And lastly, I declare that I do not claim as my In¬ vention the preserving food in air tight vessels, but the combination of the several manufactures before described, by which, in the various modes I have 35 pointed out, that object may be accomplished. In witness whereof, I, the said ^neas Morrison, have hereunto set my hand and seal, this Thirtieth day of August, in the Fifty-ninth year of the reign of His said most Excellent Majesty George the Third, by the
