Toothache.
Toothache is often a forerunner of some change of weather, like other pains, and particularly that species which depends on inflammation of a diseased socket or gum. In certain kinds of weather, and particularly before rain or showers, decayed teeth and diseased gums are very uneasy, and the pain often ceases when the rain begins to fall. The periods of that sort of toothache which depends on the exposure of the nerve in the cavity of the tooth seem to exist independently of any particular weather, and occur most frequently during the night, when the patient first gets warm in bed. The progress of this sort of toothache is often as follows: The pain after awhile becomes continuous instead of being periodical, and by degrees subsides, but the socket then and ultimately the gum become diseased, and are thence liable to be affected by the state of the weather above described.

Tortoises.
Tortoises creep deep into the ground so as to completely conceal themselves from view when a severe winter is to follow. When a mild winter is to follow they go down just far enough to protect the opening of their shells.
Trees.
Trees snapping and cracking in the fall indicates cold weather.
Vernal Equinox.
If the wind is northeast at vernal equinox, it will be a good season for wheat and a poor one for corn; but if south or southwest, it will be good for corn and bad for wheat.
Walls.
When in cold weather the walls begin to show dampness, the weather changes.
