FOR COMPUTING THE NUTATION OF A STAR IN RIGHT ASCENSION, AND DECLINATION.

TO FIND THE NUTATION OF A STAR IN RIGHT ASCENSION.

To the log. of the sum, or difference, of the Equations from Tables LVII. LVIII. answering to their proper arguments, add the log. tangent of the Star's declination; the sum will be the log. of part first of nutation, and if the declination is south, change the sign; to which apply the equation from Table LIX. answering to the longitude of the Moon's node, and the sum, or difference, will be the nutation in right ascension.

Increase the arguments of Tables LVII. and LVIII. each by three signs, and the sum or difference of

FOR COMPUTING THE ABERRATION OF A STAR IN RIGHT ASCENSION,

To the log. of the sum or difference of the equations from Tables LX. LXI. answering to their arguments, add the log. secant of the Star's declination, the sum will be the log. of the aberration in right ascension.

TO FIND THE ABERRATION OF A STAR IN DECLINATION.

Find the sum, or difference, of the equations answering to the former arguments, increased by three signs, to the log. of which add the log. sine of the Star's declination: the sum will be the log. of part 1st of the aberration. Take parts second and third of aberration from Table LXII. which, applied to the former, will give the aberration in declination. If the Star's declination is south, change the
