Electro-physiology and electro-therapeutics : showing the best methods for the medical uses of electricity / By Alfred C. Garratt.

of the heavens, state in the weather tables, as a set-off, I con- jecture, to her influence, — "If the particular change of the moon, full or new, takes place when the wind is so and so, it will be fine for the ensuing week ; and the reverse if it is not." I ask, Does this prove the dominion of the moon over the winds, or the contrary ? Magnetism. 1. The intensity of the mag- netic force in different parts of the earth is according to the distance from the poles. 2. The frigid zone, where magnetism is in the greatest intensity, enjoys an atmospheric calm which is unknown in tem- perate regions; it has no storms, no hail, and scarcely a tempest. 3. The splendor of the au- rora borealis, reflected by the snow, dispels the darkness of the polar night, but is not ac- companied with danger. 4. Magnetism suspends the decomposition of vegetable and animal matter. 5. In northern latitudes the mercury of the barometer al- ways stands high ; in the tem- perate latitudes it is liable to frequent variations. 6. Magnetism has been known to produce sedative action on the human frame, when applied under certain conditions, causing repose, if not sleep. Electricity. 1. The intensity of electric force is greatest at the tropics, and diminishes as it approaches the poles. 2. The most vivid lightning and the loudest thunder are peculiar to the tropics; here vegetation is vigorous, and ac- tive at all seasons. 3. Igneous and fiery mete- ors, fire balls, and lightning are the peculiar electrical phe- nomena of the tropics. 4. Electricity assists decom- position in all vegetable and animal substances. 5. The mercury of the ba- rometer is always low in the torrid zone, and varies but little during the changes of weather. 6. Electricity is of an ex- citing character, increasing the circulation of the blood, and rousing paralytic functions of the nervous centres.
