 Founded in 1730. 



The director has furnished the following particulars from his report 

 for 1878-1879 : 



The most noteworthy occurrence during the past year is the setting 

 apart, as an independent establishment, of the meteorological Observa- 

 tory. This new arrangement, made practicable by a government appro- 

 priation for the current expenses, is as yet in so far incomplete as in 

 absence of an independent building for meteorological purposes the 

 institute occupies two rooms in the astronomic building. - - - 



The requirements of the Observatory have been constantly increasing 

 and are now imperative as regards instruments, repairs, and proper 

 arrangements, if any kind of activity is expected. The present means 

 are quite insufficient to satisfy the most urgent needs of the establish- 

 ment. 



The only room of observation in a satisfactory condition is the small 

 Wackerbarth ca])ola, which was repaired last summer, while the meri- 

 dian room and the large cupola require considerable repairs and im- 

 provements. - - - 



The small collection of instruments of this Observatory, apart from 

 quite antique instruments, consists of the following: 



One parallactic refractor, made by Steinheil, 9 inches ax)erture, 

 the principal instrument of the Observatory, the application of which, 

 however, on account of insufficient mounting, is impracticable and lim- 

 ited. It has been employed mainly for observation of nebulae and star 

 clusters. A concise description of this instrument was given in the 

 "Mikrometrisk Bestamning af 104 Stjerner inom Teleskopiska Stjern- 

 grni)per 20 Vulpecuhie." 



One small parallactic refractor of 4 inches aperture, made by Sims, 

 in good condition, and presented to the Observatory some years ago by 

 Prof. Wackeebaeth. 



One old universal instrument of 45 millimeters aperture, by Eepsold, 

 the circles of which, however, are useless for x^ractical measurements ; 

 it has been employed for many years for time determinations in the 

 meridian. 



One universal instrument 33 millimeters aperture, by Meteestein. 



One small transit instrument 54 millimeters aperture, by Steinheil, 

 the application of which is excellent, but which, on account of insufficient 

 mounting, and too small meridian aperture (the telescope is affixed to 

 the end of the axis of rotation), has thus far not found any i^roper aijpli- 

 cation. 



A small reflex circle by Pistoe, in satisfactory condition. 



Four portable telescopes. 



One old j)endulum clock, by Geaham, reconstructed by Kessels, 

 about forty years ago. 



Two old box chronometers, by Kessels. 



One portable barometer, by Pistoe. 



The only instrument purchased during the ])ast year is an inexpensive 

 pendulum clock for exxjeriments with electrical apparatus, though order
