540 EEPORTS OF AMERICAN OBSERVATORIES. 



ing tlie past five years, were the following: "Double Stars"; "The 

 King of Sims"; "Shooting-Stars"; "The Zodiacal Light"; "A Look 

 along the Zodiac"; "The Study of Astronomy"; "The Prince of Plan- 

 ets"; "The Kinged Planet"; "A Celestial Panorama"; " The Moons of 

 Jupiter"; "The Harvest Moon"; "Venus in the Daytime"; "Prof. 

 Eichard A. Proctor"; "The Lunar Eclipse"; "Celestial Fireworks"; 

 "Frost and Dew"; "The Planetary System"; "Motions of the Stars.' 

 In 1877, 1 published a pamphlet of 36 pages, containing a lecture of 

 mine on "The Science of Astronomy," embracing its sublimity, history' 

 progress, wonders, and utility. The lecture was prepared for the pur- 

 pose of popularizing astronomy and rendering it a subject of more gen- 

 eral interest. 



VI. Additional information : 

 There is no regular observatory in connection with the high school, 

 but it consists of an apartment located on the third and upper floor of 

 the building, in which the telescope is kept and the observations are 

 usually conducted. Astronomy is taught only during the spring term, 

 and but little interest is manifested in the study by the students, al- 

 though they are permitted to use the telescope at any time. When the 

 instrument is provided with higher powers it will be equal to any of 

 its size in the State of Michigan and can be made to do some good 

 service. I have already observed five new comets with it since 187.3, 

 two having been seen in one night — May 8, 1877. Among the comets 

 observed were two discovered by Professor Savtft, of Eochester, N. Y. 

 The great work which I have had at heart has been to arouse an interest 

 in the study of astronomy, as a means of culture, especially among the 

 young, and to increase the small number of votaries in this science. To 

 this end I intend to continue my lectures and articles ;n the press, and 

 also to exhibit celestial objects of popular interest, on favorable occa- 

 sions. I will doubtless be able to send you more valuable reports in the 

 future. 



Location of observatory : (City) Brooklyn; (County) Kings; (State) 

 New York. 



I. Personnel: 

 Director, W. T. Gregg. 



(c) Equatorial instruments : Maker, William T. Gregg ; aperture of 

 objective, G£ inches; magnifying powers of eyepieces, 50 to GUI). 



VI. Additional information: 

 As I said last year, my observatory was built to facilitate corrections 

 of objectives, primarily, but I have been prevented from using it at all 

 thus far by reason of illness. I hope to be able to do something in the 

 future worthy of reporting.
