2nd. Another great defence against the Cholera, and indeed against all disorders, is _cleanliness_. This is true both of personal cleanliness, and also of cleanliness in our houses, streets, &c. As to the first of these, we do not enough consider the great importance of keeping the skin in a healthy state. The skin is a natural drain to many of the bad humours of the body. Every one knows how useful it is to get a man into a perspiration or sweat when he is ill, to set the pores of his skin open. Now dirt chokes up these pores, and thus stops what may be called the proper drainage of the body. It is very much to be wished that people in this country were more aware of the advantages of bathing or washing themselves thoroughly; not their faces and hands only but their whole bodies and limbs; it would be as useful to their health, as it would be comfortable. Again, cleanliness in our houses is very important; to get rid of all close smells by throwing open the windows, to sweep away the dirt out of holes and corners, from under beds, chests of drawers, and other places where it is apt to be left for a long-time undisturbed. Much harm is done also by any thing that stands near a window so as to hinder the fresh air from pouring into the room thoroughly, and in the same way all that crowds a room is bad, all that hinders the air from having a free course into every corner of it. Small rooms are sometimes very much choked up by bedsteads and curtains, which not only are in the way of the air, but are also great hiding places for dirt. As to the heaps of dirt and the filthy slops that we often meet with before the doors of small houses, these are absolutely public nuisances, and the Parish itself should take care that these things are looked to in time, for it will be too late when the Cholera is actually amongst us.
