CHAP. XI.
Parallels.
n parallel circles the same strength and
equal power are perceived everywhere, when various magneticks are placed on one and the same parallel either on the earth
or on a terrella. For they are distant from the poles by equal intervals and have equal tendencies of declination, and
they are attracted and held, and they come together with like forces; just as those regions which are situated under the
same parallel, even if they differ in longitude, yet we say possess the same quantity of daylight and a climate equally
tempered.
