position had occurred, and that the flavor of the meat was 

 fully preserved to such an extent, indeed, that it was con- 

 sidered excellent by himself and his friends who partook of 

 it. No taste was imparted to it by the acid different from 

 that which attaches to ordinary smoked meat, and the ex- 

 perimenter was of the opinion that this substance may be 

 used with great advantage for the preservation of flesh on a 

 large scale for a considerable period of time. He thinks, how- 

 ever, that this should be kept in well-closed vessels, although 

 it is not necessary, perhaps, that they be hermetically sealed.

SOUP TABLETS. 



The Chemical News gives us from the German Manuals of 

 Pharmacy the following receipt, by Reinsch, for making the 

 soup tablets so much in use in the German army during the 

 late war. The formula is as follows : Take eleven parts by 

 weight of good suet, melt it in an iron pan, and make it very 

 hot, so as to become brown ; add, while keeping the fat stirred, 

 eighteen parts of rye meal, and continue heating and stirring 

 so as to make the mass brown ; add then four parts of dried 

 salt and two parts of coarsely pulverized caraway seed. The 

 mixture is then poured into tin pans somewhat like those used 

 for making chocolate into cakes. The cakes have the appear- 

 ance of chocolate, and are chiefly intended for the use of sol- 

 diers while in the field. A quantity of about one ounce of 

 this preparation is sufficient to yield, when boiled with some 

 water, a ration of good soup; and in case of need, the cakes, 

 being agreeable to the taste, may be eaten raw. 1 A, March

TAPIOCA BEEF BOUILLON. 



According to the Scientific Review, a London firm, entitled 

 the " Tapioca Beef Bouillon Company," manufactures a very 

 palatable and nutritious compound which, by the mere addi- 

 tion of water, is converted into soup. It is the invention of 

 Mr. Geyelin, and consists of granulated Brazil tapioca satu- 

 rated with Liebig's extract of beef, and thoroughly dried. 

 Each canister contains the quantity necessary for a pint of 

 good soup; and as five of these canisters are sold for a shil- 

 ling sterling, this " tapioca beef bouillon" is obviously within
