90 THE NATIONAL SCIENTIFIC INSTITUTIONS AT BERLIN. 



To ordinary membership only siicli persons are eligible as are residents 

 of Berlin or live in places the connection of which with the national 

 capital permits them to take part in their regular academic duties. 

 Any such member removing to a place not provided for in the above is 

 transferred to the number of honorary members. 



Each class may have twenty-seven regular members. A number of 

 these places is intended for certain specified branches of science ; for 

 the remaining places all scientists whose activity lies within that speci- 

 fied section may become eligible. 



Vacancies among specialists may be left open, yet, the advantage of 

 the academy requires all possible competition. In that case the class has 

 to decide whether any of its members may be selected for the purpose. 

 Applications for these places can emanate only from regular members. 



A proposed class election is to be communicated to the presiding sec- 

 retary of the academy and then considered by the entire academy at its 

 next regular session when the candidate is elected by ballot. 



The result of the election is to be communicated to the minister who 

 obtains the king's approval. 



If a scientist, non-resident of Berlin or of any of the places allowed 

 for, receives the election of regular member he is required to remove to 

 Berlin within six months of the date of his confirmation — which time 

 may be increased in special cases. If he fails to comply with this rule 

 he is enrolled among the honorary members. 



The regular members are both permitted and required to share the 

 labors of the Academy ; they have a seat and a vote both in the general 

 Academy and in the class, and are permitted to attend the meetings of 

 either of the classes. 



A member of twenty-five years standing or having reached the age 

 of seventy may be relieved from lecturing or speaking. 



The regular members are entitled to all privileges of the royal insti- 

 tutions and collections. They are furthermore privileged to lecture at 

 any university of the Prussian domain and enjoy equal rights with the 

 professors in accordance with regulations to which they are also bound 

 with regard to the lectures. 



With regard to salaries the following regulations are in force : 



(1) Each of the fifty-four regular members of the Academy receive an 

 annual salary of 900 mark ($225.). 



(2) Separate salaries, additional to the above 900 mark are given to 

 two regular members of the physico mathematical class, of which one 

 has to be a botanist and the other a chemist, and to two regular mem- 

 bers of the philosophic-historical class, who are required to be phi- 

 lologists or historians. The salary of the chemist also includes the 

 official dwelling in the building of the academy and the use, for scientific 

 purposes, of any available room in the building not otherwise occupied. 

 The payment of such a salary is made for special services required in 

 the conduct of a certain office or professorship, or in the directiou of a 

 scientific institute.
