ASTRONOMY. 147 



The following financial statistics, some of which may be found in 

 farther detail in the report of the treasurer of the university, will be of 

 interest : 



Value of grounds, Harvartl Observatory $80, 000 



Valvie ofbuildings 25,000 



Value of instrumeuts 40,000 



Endowment 398,000 



Total 543,000 



Tlie available annual income, including gifts for immerliate use, is 

 $22,000. The salary of the director is #3,400, the use of the house being 

 estimated at $600 more. The sale of time signals brought in nearly 

 $3,000 during the year. The principal items of expenditure are — 



Total expenditure for salaries, including that of director $12, 000 



Total expenditure for iustruiuents 800 



Total expenditure for publications 3,500 



Repairs and improvements on buildings and grounds 940 



Tlie personnel includes Professor Pickering, the director; assistant. 

 Prof. W. A. Kogers (resigned September 1, 1S8G) ; assistant, Prof. A. 

 Searle ; and Messrs. Wendell, Edmands, Eitchie, Gerrish^ Giflford, and 

 Metcalf ; with six computers, ladies. 



The Boyden fund, which was left for the purpose of astronomical 

 research '' at such an elevation as to be free, so far as practicable, from 

 the impediments to accurate observations which occur in the observa- 

 tories now existing, owing to atmospheric influences," has been trans- 

 ferred to Harvard College and will be administered at the observatory. 

 The fund at present exceeds $230,000. Professor Pickering proposes to 

 establish an experimental observing station in Colorado, but desires to 

 occupy ultimately some high mountain peak in the southern hemisphere 

 where observations — largely photographic, probably- — can be carried on 

 in co-o[)eration with Cambridge. Information in regard to eligible sites 

 south of the equator is much desired. 



Heidelberg (1886). — Private observatory of Dr. Wolf. The principal 

 instrument is a 6-inch equatorial ; objective by lieinfelder «& Hertel, 

 mounting by Sendtner, of Munich. A photograph of the observatory 

 is given in Sirius, vol. 19, Heft 12. 



HeUingfors (1885). — Dr. Donner has continued to observe the moon, 

 moon-culminating stars, and planets, with the large transit instrument. 

 This instrument is to be remodeled by Repsold into a meridian circle. 

 A portable transit of 6.9°" (2.7 inches) aperture by Repsold has been 

 mounted in the prime vertical. The equatorial has been used for ob- 

 serving comets. 



Hereny (18S5). — The mirror of the 10|-inch reflector having been re- 

 silvered by Professor Safarik, the instrument has been arranged for 

 experiments in celestial photography. Herr von Gothard has succeeded 

 In photographing several constellations, star-clusters, nebulae, and stel- 

 lar spectra, but the work is still regarded as experimental. Spectre-
