On the 9th and icth, the Sun’s rays were allowed to fall upon the instrument, after 
the star at its sw&-polar transit, had passed the wire D. 
On the 1 2th and 16th, the instrument was exposed to the Sun, after that the star 
at its stt&-polar transit, had traversed the wire E. 
With these exceptions, the instrument was entirely defended , from the Sun’s rays. 
* These observations (the clock’s daily rate being nearly insensible), indicate 
slight ex-meridian position; and may serve as a practical illustration, of the state- 
ment made in page 432; seeing, that seven months have elapsed, since the instru- 
ment was moved by its azimuthal adjustment ; and that nearly seventeen have 
transpired, since non-horizontality of its axis, could be detected.
