Observatory Notes

At the Observatory, for the last few days, there has been an interesting exhibit of glass positives and paper prints, illustrating the buildings which the Observatory has occupied at various stations, and the astronomical instruments used there. Besides these, the exhibit contains several photographs of stars, moons, and spectra.

This collection will constitute the exhibit from the Observatory to the Paris exhibition, and will be the only one sent by an American observatory.

Professor William Pickering is now trying to find the orbit and the future position of Phoebe, the ninth satellite of Saturn, which was discovered last year at the Harvard Observatory. Thirteen photographs have been taken, which show the satellite.
