Angles of the parallactic Motion with the Parallel.
The difference between these parallactic, and the former apparent angles, with the parallel of each star, will give the required angles for our second figure. They will be as follows.
Angles of the apparent with the parallactic Motion
By these angles, with the assistance of the lines s a, whose lengths represent the annual quantity of the apparent motions as given in our former Table, the Figure No. 2 has been constructed. When the situation of these angles is regulated as in that figure, we may draw the several lines m a perpendicular to S P, and, by computation, their value and sum will be obtained as follows.
