Many persons put lime-water into the milk to make it digestible. In doing so they put a difficulty in the way, in the shape of the lime. If one tries to wash his hands in "hard" water, he sees how unfit that water is to do the proper work of water in the blood and tissues of the body. Now, it is not difficult to meet this evil where the only water to be had has a great deal of lime in solution. Boiling this water makes it deposit much of its lime. If a very, very small bit of soda is mixed with it in the boiling, it lets down its lime more quickly and completely. Alcoholic drinks--wine, porter, or ale--are often given as means of nourishment. They are hurtful in the extreme, as the spirit contained in them spoils, so far as it acts, both the saliva and the gastric juice. Rum and milk, sack whey, and other such preparations are equally bad, and have killed many a patient. While suitable nourishment is necessary for the sick, great care should be taken to avoid giving too much. Often the amount of food the patient requires or can assimilate is _exceedingly small_. Injudicious attempts to "keep up the strength" by forcing down food that cannot be digested often destroy the little that remains, and remove the only hope of cure.

Nourishment, Cold in.--If a person is in fever, and is burning with internal heat, a little bit of ice, sucked in the mouth, gives great relief. The relief is got in this way: the melted ice, in the form of water, is little in bulk in proportion to the heat which is absorbed in melting it. To absorb the same heat by means of merely cold water, would imply a great amount of water, and an inconvenient filling of the stomach. The heat used up in melting the small bit of ice is great, and the amount of water exceedingly small. This gives benefit without inconvenience; hence, to suck a bit of ice is to be much preferred in such a case to taking a drink of cold water. Within proper limits, beyond all question, cold is, in certain cases, essential to nourishment. For example, in a case of thirst such as we have noticed, the heat of the stomach extending to the mouth is drying up all the juices that should go to secure digestion and assimilation. The saliva is dried up, and the gastric juice equally so. Cold is applied to the pit of the stomach (not ice, but a moderate degree of repeated cold), and the result is, these juices begin to flow. Nourishment is the consequence, and very clearly, in such a case, it is the consequence of cold. In other words, it is the result of reducing the excessive internal heat, and leaving something like the proper degree behind.
