Charles. It seems to me that but very little impure matter can be conveyed away in the perspiration which falls from us.
Father. Even when we cannot perceive the perspiration, there is what is called insensible perspiration, by which, in a state of health, about twenty ounces of waste matter are daily removed. When a person takes a sudden cold, this perspiration is checked, and the waste matter accumulates, and causes sickness. Perspiration takes place with much more regularity when the body is kept perfectly clean, than when it is allowed to remain dirty; and from this we can see how necessary it is to bathe the body thoroughly and frequently, and also that we ought to avoid exposing ourselves to take cold.
Albert. I thank you, father, for explaining these things, and will try to remember them.
Charles. And so do I: and I hope that another evening we shall learn much more.
