The sum of these two means (61+), agreeing so satisfactorily with the whole rotation (611/2), no correction is requisite, as was the case with the former determinations of 1796 to reduce them to 28 and 35 days, results that differ considerably from the above (34 and 27+); but as they were deduced from only two intervals, the disagreement cannot be of any consequence, provided the number of each set be proportionally
