110 THE NATIONAL SCIENTIFIC INSTITUTIONS AT BERLIN. 



The Institute is to be regarded as a central point for the collection, 

 computation, and publication of meteorological stacious of North Ger- 

 many, the meteorological systems of Oldenburg, Mecklenburg, Hesse, 

 the Saxon states and other smaller states having combined with it. 



The system represents the following arrangement of stations : 



(a) One hundred and thirty stations of Class II, that is, such stations 

 making three observations daily of all the instruments. 



(b) Fifty stations of Class III, at which a limited number of instru- 

 ments is observed twice daily. 



(c) Eighty rain-fall stations. 



At present a i)lan is under consideration for the incorporation in the 

 system of the stations (about one hundred and fifty) of the " Society 

 for Agricultural Meteorology in the provinceof Saxony and in the Uck- 

 ermark," and of the stations of the "Agricultural Central Association 

 of Lithunia and Masuren." 



The appropriation for the Institute for the administrative year 1880-87 

 amounted to 73,060 mark ($18,265), of which 32,560 ($8,110) were in- 

 tended for salaries of ofiScials, assistants, and computors, 21,000 mark 

 ($5,250), for the payment of observers on stations, and 19,500 mark 

 ($4,875) for other expenses. For architectural changes within the 

 rooms occupied, and for the purchase of instruments, 44,000 mark 

 ($11,000) were allowed by special act and further amounts promised 

 during the coming year. 



The Physical Institute. — Upon the extensive space lying between the 

 Neue Wilhelmstrasse, Schlachtgasse, Dorotheenstrasse and river Spree 

 two large buildings are located, each of 108 meter frontage, of w hich 

 the one along the Dorotheenstrasse has been fitted up for the Physio- 

 logical and Pharmacological Institutes, while that facing the Spree is 

 occupied by the Physical and the Secoud Chemical Institutes, all being- 

 provided with the required directorial dwellings. 



The total cost of the entire structures is 4,500,000 mark ($1,125,000), 

 of which 200,000 ($50,000) were paid for the foundations of the Physi- 

 ological Institute, 310,000 ($77,500) for that of the Physical Institute, 

 120,000 ($30,000) for that of the Pharmacalogical Institute, 110,000 

 ($27,500) for that of the Chemical Institute and 60,000 ($15,000) for 

 those of the dwelling houses, representing 800,0'v.*0 mark ($200,000), 

 or almost one-fifth of the entire cost of construction. 



Until the year 1833 the University did not possess any i)roper col- 

 lection of i)hysical apparatus, though a few instruments employed in the 

 course of lectures by professors had been purchased and placed in the 

 hands of professors using them for scientific investigation. It is true 

 that the University had allowed 500 thaler ($375) annually for In- 

 creasing the collection of physical apparatus, yet the money was gen- 

 erally employed for other purposes. The want of proper apparatus be- 

 came apparent when Professor Magnus, the late director of the col'
