antedating of "clock wise" (1882)

[Sam Clements]

OED and M-W both have 1888. 

>From APS online    _American Journal of Science_  June 1882; 23,138, p.460

    "When the rotation of the plane of polarization appears clock-wise to the observer, it has the character of a left-handed screw.  But the circularly polarized ray to which Vr relates, the rotation of which also appears clock-wise to the observer, has the character of a right-handed screw."

The article was about circular polarization.  There are other cites between 1882 and 1888 for clock-wise, and all used in scientif papers, as was the 1888 one on hurricanes.

I guess a scientist just needed a term which more efficiently described a motion that could only be indicated with hand gestures.
