Effects of Alcohol on Animal Heat.~--A large part of the food we eat is used in keeping our bodies warm.

Most of the starch, sugar, and fat in our food serves the body as a sort of fuel.

It is by this means that the body is kept always at about the same temperature, which is just a little less than one hundred degrees.

This is why we need more food in very cold weather than in very warm weather.

He feels warmer, but if his temperature be ascertained by means of a thermometer placed in his mouth, it is found that he is really colder.
