Take one pound of sirloin of beef; warm it on a broiler before a quick fire; cut into cubes of about one-quarter of an inch, and after placing in a lemon squeezer or meat press, forcibly express the juice; remove the fat that rises to the surface after cooling.

This may be given warm or cold, and seasoned with a little salt, in doses of one teaspoonful every two hours to a child of six months to a year old.

The meat must never be actually cooked and must be fresh and sound.
