- Latin evagatio, from evagari to wander forth: compare French évagation. See vagary. (Wiktionary)
“In October I had drawn up a list of days for a possible evagation of the Earth's poles: but apparently nothing was done upon them.”
“Whence it follows, that (fup - pofing the earth's rotatory motion to be difturbed only by the centrifugal force arihng from the inertia of its own particles) the track of polar evagation with us will be nearly circular, and the radius of the limiting circle very fmall, whether we have regard to the moveable or immoveable fpherical furface referred to above; but that, in the latter furface, fuch circle will be much lefs than in the former: and it moreover follows, that the con - cavity of the track upon the moveable furface will continually touch and roll along the convexity of the track in the immove - able furface.”

Interesting words appearing in Samuel Johnson's Dictionary (1755). Some are interesting for their unfamiliarity, and some for the meanings then assigned by Johnson.
Unexpected or not. :)
