As we learn from the Journal of the Amer- 

 ican Medical Association, the appeal for the 

 erection of a monument to Robert Koch has 

 now been issued. As announced, the honor- 

 ary presidency of the committee has been 

 taken by the imperial chancellor while the 

 acting president is the new chief of the state 

 medical department. Professor Kirchner. To 

 the committee belong, in addition to most of 

 the members of the Prussian cabinet and the 

 cabinets of the other states of the empire, the 

 mayor of Berlin and the mayors of a large
