The place of the star being deduced from the Tables in the Appendix to Dr. Pearson's Practical Astronomy. Immersion Emersion 6h. 33m. 57s. A. 0.31" South of the S. D. of 2.59"; apparent motion of ♂ per minute in Long. 1.532′′, in Lat. +0.010". This will probably be an occultation throughout a very large part of the United States; but it is very doubtful whether it can be observed in any place much to the westward of Boston, on account of the proximity of the Sun to the horizon. It takes place, however, at a season of the year when the twilight is about the shortest, and at a time when the star has great altitude.
