    A.D. 1854, July 12.—N° 1534. BELLFORD, Auguste Edouard Loradoux.—This invention received provisional protection, but notice to proceed with the application for Letters Patent was not given within the time pre¬ scribed by the Act. The title was “ Improvements in preserving “ animal substances,” and this was to be effected by means of a solution of sulphurous acid. “ In order to prevent the sulphurous “ acid from combining with the bases of alkaline carbonates found “ hi the meat, and thus giving to the meat a disagreable taste “ arising from the sulphite formed,” about one hundredth part of hydrochloric acid is added to it. “ Into this solution then the “ meat ” “ is immersed, and kept in any suitable vessel, which is “ sealed or confined hermetically.” “ The meat or other animal “ matter may also be preserved by keeping it immersed during “ twenty-four hours, about, in a concentrated solution of sulphur- “ ous acid, and then keeping it for the remainder of the time in “ pure water.” [Printed, 3(7.] A.D. 1854, July 21.—N° 1600. DELABARRE, Toussant, and BONNET, Leon.—This inven¬ tion did not proceed to the Great Seal. The title was “ The pre- “ servation of meat in its natural state, and without being cooked,” and this was to be effected by “exposing to the action of a “ machine (such as is used for drying linen), having a wheel “ which revolves with the greatest velocity,” fresh meat, by which means any moist substance dries rapidly. When about half the moisture is gone, the meat “ is plunged for a short time (a “ minute or two) in heated gelatine, made from the bones and “ sinews of animals, hung up in a well-ventilated room, and dried.” “ The gelatine enters the pores of the meat, replacing the water “ which has been driven out.” [Printed, 3(7.] A.D. 1854, August 5.—N° 1 /ID. STANSBURY, Charles Frederick.—(A communication from Robert Arthur, M.D.)—The title of this invention is as follows: “ Improved air-tight vessels,” applicable “ for ordinary domestic “ use,” by “ forming at or near the top of jars, pots, cans, bottles, “ color plates, inkstands, and other vessels which it may be desired
