48 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



secure against vibrations. The instruments to be used in this way 

 are a 9~inck Silccred-glass Reflector, by Browning ; a Comet-seeker, of 

 G inches aperture, by Fitz, and a 3-inch Telescope, by Fraunhofer. 



The time is furnished by two standard Clocks (one Solar and one 

 Sidereal), and by 5 subsidiary Clocks electrically controlled by the 

 standard Sidereal, one in each of the observing-rooms. The Clocks 

 are by Howard & Co., of Boston, and the Sidereal standard has the 

 new escapement invented by Professor Young. Both this and the 

 Solar Clock have a modification of Robinson's barometric conden- 

 sation. 



The Chronograph, by Clark, has three independent cylinders. 

 This and the standard Clocks are mounted in a room which is heated 

 in cold weather. The cost of the whole was about $23,000. 



The building and its equipment will be used mainly for the pur- 

 pose of teaching practical astronomy to select classes. Its equip- 

 ment is such, however, that it will be possible to do some real as- 

 tronomical work in the way of determining star positions with the 

 Circle, observing occupations and similar phenomena, measuring 

 double stars, and especially in keeping up a series of solar observa- 

 tions, ocular, spectroscopic, and photographic. 



Experience only, however, can determine how much of this work 

 will be practicable without interfering with the work of instruction, 

 which will always hold the first place. 



At present Professor Young is without assistants ; but it is hoped 

 that before long the want will be provided for, either by persons 

 specially appointed or by post-graduate students. 



Observatory of Quebec. 

 Commander E. D. Ashe, R.N., Director. 



1st. The personnel consists of myself and assistant. 



2d. Two Clocks a Sidereal one, by Dent, and a Meantime one, by 

 Molyneux ; a 3G-inch Transit, mounted between stone piers ; and a 

 splendid Equatorial, of 8 inches clear aperture and 9 feet focus, by 

 Ativan Clark; a 42-inch Telescope, by Dolland. 



The principal object of the observatory is to give time to the ship- 

 ping by dropping a ball at one o'clock, showing 5 h 44 m 49 s Green- 

 wich time. Besides this, I have been very successful in solar photog- 

 raphy. There will be no alteration in the observations during the 

 next year. 



Observatory of Ripon College, Wisconsin. 



Professor C. A. Kenaston, Director. 



This observatory contains a fine Transit Instrument, a Mitchell 

 Chronograph, and a good Astronomical Clock.
