SCIENTIFIC NOTES AND NEWS 



A COMMITTEE has been formed in Germany, 

 with the Prussian minister of state as chair^ 

 man, to found an institution in honor of Dr. 

 Robert Koch. It is intended that the institu- 

 tion shall be devoted to research into the 

 means of checking the diffusion of tuberculosis 

 and that it shall be a permanent memorial of 

 the discovery of the tubercle bacillus by Pro- 

 fessor Koch twenty-five years ago. Appeal ia 

 made for contributions sufficient to make the 

 institution a tribute of gTatitude to Koch, 

 similar to those with which the name of 

 Pasteur has been honored in France and that 

 of Lister in England.

 Society was founded.

 partment of the University of Michigan, has 

 been appointed by the Interstate Commerce 

 Commission to act as chairman of a com- 

 mittee which will meet in Washington to con-
