To a quarter pound of finely-minced, raw lean beef add a half-pint of cold water; cook over a slow fire to boiling and boil for a few minutes, stirring constantly from the beginning. Pour off the liquor and set it aside; rub the meat to a paste and put it into a clean glass jar or bottle with the liquor and a half pint of cold water; add

sionally, then boil quickly, strain, or clarify with white of egg in the usual manner; season to taste.

This final boiling is essential; if omitted, digestion will progress until the food is spoiled.

For the great majority of cases, it is not necessary to strain the peptonized beef, for the portions remaining undissolved are so softened under the action of the Extractum Pancreatis that they are diffused in an almost impalpable condition - in a form readily susceptible to digestion in the body.

Chicken meat, alone, or mixed with an equal portion of beef, may be prepared in the same way.

A cereal gruel, of wheat, arrowroot, etc., may be incorporated with the beef, thus giving a food combination that is often highly desirable.

The gruel is prepared in the usual manner, the dry cereal mixed perfectly smooth with cold water and cooked slowly in a double boiler until gelatinized. Four ounces of this gruel may be added to the meat paste, liquor, water and peptonizing powder as directed above, and the further details of the process carried out just as with the beef alone.

The Extractum Pancreatis will at the same time digest both the meat and starch (of the gruel). The broth with the cereal is more agreeable than when made of meat alone.

The peptonized beef or peptonized beef and cereal may also be made into a jelly.
