He'misphere. n.s. [ἡμισφᾶιριον; hemisphere, French.] The half of a globe when it is supposed to be cut through its centre in the plane of one of its greatest circles.

That place is earth, the seat of man; that light
His day, which else, as th' other hemisphere,
Night would invade. Milton's Paradise Lost, b. iii.

          God saw the light was good,
And light from darkness by the hemisphere
Divided. Milton's Paradise Lost, b. vii.

                        A hill
Of paradise, the highest from whose top
The hemisphere of earth, in clearest ken
Stretch'd out to th' amplest reach of prospect lay. Milt. P. L.

The sun is more powerful in the northern hemisphere, and in the apogeum; for therein his motion is slower. Brown.

In open prospect nothing bounds our eye,
Until the earth seems join'd unto the sky;
So in this hemisphere our utmost view
Is only bounded by our king and you. Dryden.
