These are the Corrections of the Parallaxes of the ten workings of the Author, to reduce the Star to the altitude of 32 Semidiameters. gr. m. sec. gr. m. sec. 04	22	30	in	04	42	30 00	04	00	in	00	10	00 00	10	00	in	00	14	00 00	37	00	in	00	42	30 00	07	00	in	00	18	00 00	42	00	in	00	43	00 00	14	50	in	00	15	00 04	28	00	in	04	30	00 00	35	00	in	00	55	00 01	16	00	in	01	36	00

From hence we see, that to reduce the Star to 32. Semidiameters in altitude, it is requisite from the sum of the Parallaxes 836. to subtract 756. and to reduce them to 80. nor yet doth that correction suffice.
