58 height of the barometer, and the fire must act with a stronger force to lift up the water with a greater pressure than with a less, for the same reason Urine lukewarm will boil under an exhausted receiver. W.J. Magnetism is owing to fire; for Mr. Franklin says, that with a very strong shock of electricity he has given magnetism to iron, and it is past all doubt that electrical effluvia is fire; for it has great similarity with lightening, we have also often heard of lightening destroying the mariner's magnet, and even sometimes its [[strikethrough]]the[[/strikethrough]] poles [[strikethrough]]of the magnet[[/strikethrough]] are turned quite round, or altered to the direction the lightening proceeded in; or the effect of it has been augmented or diminished: farther, by heating a bar of iron red hot and quenching it with the ends North and South, it will have some degree of Magnetism. Moreover, in [[underlined]]Nova Zembla[[/underlined]] the needles were so frozen as to lose their magnetism, and would have it again by holding it to the fire but no longer. Soft iron having the least pressure & containing least fire will receive magnetism easiest but retain it the shortest time. harder iron having a greater pressure and more fire receives magnetism not so easy, but will keep it longer. Case- hardened iron having the greatest pressure and most fire, will not receive it at all. W.J. Job XXVIII. 26 [[underlined]]When he[[/underlined]] (GOD) [[underlined]]made a decree for the rain, and a way for the lightning of the thunder[[/underlined]]: at the time of thunder and lightning the earth is supposed to be full of electrical matter, like the electrical tube or bar, and the clouds being nonelectric bodies, like those applied to the tube or bar, they, by approaching the earth, discharge fire with a report; as is represented in miniature by electricity: and as the electrical fire proceeds from a non electrical body to the bar, v.p. 46 that way wherein it meets with least resistance (whether it be the shortest or not) so the fire proceeds from the clouds towards the earth, through the rarest and driest part of the air, because it then meets with the least resistance, and has various turnings & windings in its progress, as is evident from the best Thermometer's being in a continual flux for every moment of Time. W.J. The sum of the Heats in Summer and sum of Coldness in Winter are more moderate and more severe periodically, each period including several years, tho' not always of the same Number, for at the poles the solar refraction makes their half year of sun 7 months; and the prevailing rays reflected strongly from the frozen sea including the countries between the latitude 60 and 70 (those of a greater lat. being thaw'd) a continent of ice and innumerable mountains of the same kind of glass, must in one month produce such a thaw as will disjoin them and set them a float. This will happen about the middle
