728 PROGRESS OF ASTRONOMY FOR 1891 AND 1892. 



of iiebuliie lias been imdertakeii and some furtlier observations have 

 been made at Duneclit, but little observing has been done pending the 

 completion of the new buildings. The main building of the new ob- 

 servatory is to be 180 feet from east to west, terminating in two towers 

 surmounted by domes, or rather ^^drums." The eastern tower, rising 

 to a height of 75 feet, will contain the 15-inch Grubb refractor, while 

 the 24-inch reflector from the old site at Caltou Hill will be mounted 

 in the western dome, A single range of rooms, opening on a corridor 

 on the south, extends from tower to tower. The roof is designed as 

 an asphalted platform, affording free communication between the 

 towers. Beginning at the west there are a spectroscope room, general 

 laboratory, electrical room, cleaning room, mechanic's workshop, chrono- 

 graph and class room. Light and dark photographic rooms, as well 

 as a computing room for tlie equatorial and photographic work, are in 

 the eastern tower. A central extension of the building toward the 

 south, 80 feet by 26 teet, will contain the chief computing room, hall- 

 way, etc., director's room, and iire-proof library — 34 feet by 23 feet, 

 with a light iron gnllery affording access to the upper shelves. An up- 

 per story to the southern part of this portion of the building, 00 feet 

 in length, is designed for optical work. In the basement will be placed 

 the heating apparatus, a dynamo, and accumulators for supplying elec- 

 tricity for lighting the observatory and illuminating the instruments. 

 In the observatory there will thus be but one chimney. 



The transit circle will be in a separate building, with light walls and 

 roof of corrugated iron, 80 feet west of the western tower, accessible by 

 a covered way. The remaining buildings are the astronomer's house, 

 two assistants' houses, and a gate lodge. 



Geneva : Gautier. — Col. Emile Gautier died on February 24, 1801, 

 and was succeeded in the directorship by his son, li. Gautier. The 

 principal work of the observatory is the testing of watches and chro- 

 nometers, and meteorological observations, A number of observations 

 of comets have also been made, 



Glasgow. — Meridian circle observations. 



GoTTiNGEN: Schur. — Observ^ations of asteroids, comets, andPra^sepe, 

 and measures for stellar parallax; regular meridian observations, and 

 j)hysical observations of the moon, Jupiter, Saturn and Uranus. 



(tOODSELl: Payne. — The observatory of Carleton College received a 

 new name, in honor of Mr, C. F, Goodsell. the founder of Carleton Col- 

 lege, on June 11, 1891. 



The new Williams equatorial, costing $15,000, was installed in 1891. 

 Its clear aperture is 1G.2 inches and focal length 22 feet, the lenses 

 having been figured by Brashear upon Hastings' curves and the mount- 

 ing jjrovided by Warner and Swasey. 



GoTHA : ifars-er.— Reduction of previous observations. The director's 

 time has been given almost entirely to lectures and to his theoretical 

 investigations.
