Excerpt from Zone Catalogue of 4050 Stars for the Epoch 1885: Observed With the Three-Inch Transit of the Cincinnati Observatory In reducing the observations the times of transit were corrected for inclination of the lines to the meridian, and the micrometer readings for differential refraction. Tables were formed for each zone giving the reduction to the beginning of 1885 for the middle declination and for convenient intervals of right ascension.
