ASTRONOMY. 147 



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

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

 interest : 



Value of f^rounds, Harvard Observatory $80, 000 



Value of buildings 25,000 



Value of iustrunieuts 40, 000 



Eudowmcut 39d,000 



Total 543,000 



The available annual income, including gifts for immediate use, is 

 $22,000. The salary of the director is 13,4:00, the use of the house being 

 estimated at $000 more. The sale of time signals brought in nearly 

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



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



Total expenditure for iustrunieuts 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. liogers (resigned September 1, 188G) ; assistant, Prof. A. 

 Searle; and Messrs. Wendell, Edmauds, Ritchie, Gerrish, Gifford, and 

 Metcalf ; with six computers, ladies. 



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

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

 the impediments to accurate observations which occur in the observa- 

 tories now existing, owing to atmospheric iulluences," 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 observ^ations — largel}^ photographic, probably — can be carried on 

 in co-operation with Cambridge. Information in regard to eligible sites 

 soutli of the equator is much desired. 



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

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

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

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



Hclsingfors (1885). — Dr. Donuer has continued to observe the moon, 

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

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

 A portable transit of 6.9='" (2.7 inches) aperture by Eepsold 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 phologra[)hy. Uerr von Gothard has succeeded 

 in photographing several constellations, star-clusters, uebuhe, and stel- 

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