Observatory Notes.

Under the supervision of Mr. E. C. Pickering the exhibit of the Observatory and its branches has been selected and set up as it is to appear at the Paris Exposition. One hundred and four square feet of wall space have been reserved in the United States section for the exhibit, which will consist of sixteen transparencies from original plates taken at Cambridge and Arequipa, three wing frames holding about two hundred pictures of star clusters and planets, and twenty wall pictures of work done at observatories. The exhibits are arranged in order to a height of thirteen feet.

When the long telescope now in process of construction is completed, it will be tried first at Cambridge and afterward sent to Jamaica, where a site in the western part of the island suitable for an observatory was selected last year by Professor W. H. Pickering. After observations have been made there, the telescope will be removed to Arequipa, Peru.

Preparations have been made to observe the five-days meteor shower, which begins on the 13th of this month, and is not expected to occur again for thirty years. A limited number of students in the astronomical department will be allowed to assist at the observations.
