For patients suffering with fevers, and for use in very warm weather, good ice-cream and sherbet are most acceptable. They should, however, be used with great care, particularly if the illness be due to disturbance of digestion, for they lower the temperature of the stomach and often cause such disorders as lead to severe illness. Even if this does not happen, they, in order to be raised to a temperature at which digestion will take place, absorb heat from the body, and a person reduced by illness cannot afford to needlessly part with any form of energy. Sherbet in its literal sense means a _cool drink_. It is of oriental origin, but in this country it has come to mean a frozen mixture of fruit, or fruit-juice, water and sugar. There is a distinction made, however, between water-ice and sherbet. Sherbet has, in addition to the fruit-juice and water, either sugar-syrup, white of egg, or gelatine, to give it sufficient viscousness to entangle and hold air when beaten in a freezer, so that sherbets (unless colored by the fruit used) will be white and opaque like snow. Water-ices, on the contrary, are made without the white of egg, syrup, or gelatine, do not entangle air, and are translucent and what might be called "watery." Both are delicious when made with fresh, ripe fruit, and both may be enriched by the addition of sweet cream if desired. =Freezers.= Of the various kinds of freezers perhaps the "Improved White Mountain Freezer" is, everything considered, as good as any. It is strong and freezes quickly when the salt and ice are properly proportioned. It is well to study the gearing before attempting to use a freezer. The different parts should be taken apart and put together until it is understood how the machine works. See that the paddles in the can do not interfere with each other, and that the crank turns easily. Then put all together again, fasten down the crank-bar across the top of the can, and have everything in readiness before packing the freezer with salt and ice. The object in using the salt is to get a greater degree of cold than could be obtained with the ice alone. The affinity of salt for water is very great--so great, that it will break down the structure of ice in its eagerness for it. Heat is involved in this process of melting, and will be drawn from surrounding objects, from the can, the bucket, the cream, and even the ice itself. The more rapid the union of salt and ice, the more heat is absorbed, consequently the greater is the degree of cold and the quicker the mixture to be frozen will become solid.
