Excerpt from book: ANATOMY OF THE SEASONS. LOCAL CIRCLES OF ELECTRIC ACTION. Annual Circle.?Of the local circles of electric action which preside over and control the principle of its temperature, and the other phenomena of the atmosphere,?as being that which, together with comprizing within it one entire revolution of the seasons, constitutes the basis of the action of the electrical and magnetic forces in the minor, or lunar and diurnal circles :?the annual circle, as connected with meteorology, is that which necessarily holds the first place; and in the order of precedence requires should be the first treated of. The electrical tides in the annual circle,?as refers to either hemisphere of the earth, are in number but two, viz. the positive or solar, which has its commencement with the increase in the length of the day, immediately after the period of the winter solstice, and its termination, relatively, with the increase in the length of the day, immediately after the period of the summer solstice ;?and the negative or planetary tide, which commences with theincrease in the length of the night, immediately after the period of the summer solstice, and terminates with that of the consecutive increase in the length of the night at the period of the winter solstice. Thus, it will he perceived, that these opposite electrical tides, which, as stated, induce in each of their revolutions that of the seasons ;?commence by minor, and thence go on continually increasing as they progress, till, finally, they terminate in major degrees of force:?each, in the order of its progression, exhibiting a graduated scale of action from its commencement at 1, to its termination, at?suppose? 100. Again, each of these electrical tides in its action on the atmosphere, converges to, and diverges from a main foc...
