Antecian
ANTE'CIAN, noun [Gr. opposite, and to dwell; Latin antaci.]
In geography, the antecians are those inhabitants of the earth, under the same meridian, and at the same distance from the equator, but, on opposite sides, one party north, the other south. They have the same hours of day and night, but different seasons; it being winter with one, when it is summer with the other.
