B.P. Mistura Spiritus Vini Gallici.

Preparation. - By rubbing up the yolk of the egg with 1/4 oz. of fine sugar, then adding one wineglassful (2 fl. oz.) of brandy and another of cinnamon-water, and beating them all up together.

Uses. - White of egg forms insoluble albuminates with a number of metals, and hence is employed as an antidote in cases of poisoning (especially in the cases of corrosive sublimate and sulphate of copper); in these cases the albuminates generally dissolve readily enough in the gastric juice, and therefore you must give an emetic at once.

The white and yolk of egg are useful as nutritious articles of diet, and in the form of egg-flip (mistura spiritus vini gallici) is much used in exhausted conditions of the system (p. 773). One case in which eggs are very useful is cancer of the rectum, since, being entirely absorbed in the alimentary canal, disturbance in the rectum is avoided. A good mixture is the white of three eggs, the yolk of two, and a quarter of a pint of beef-tea, beat up separately and then together, put in hot water until set, and given in two or three portions.

Eggs are often mixed with a little pancreatin, and administered as enemata.
