 NEWS ITEMS 



We learn from the Tribune (May i) of the death of Dr. Pehr 

 Olsson-Seffer in a train, wrecked and shot at by Mexican revo- 

 lutionists. The week-end special train for Cuernavaca, seventy- 

 five miles south of Mexico City, was stopped by the firing of a 

 volley through it and its derailment. Dr. Olsson-Seffer, who 

 was widely known for his work in tropical botany and agri- 

 culture, was born in Finland, went to Australia and subsequently 

 to California where he became instructor in Stanford University. 

 Latterly he made a tour of the tropical world to study the rubber 

 industry, and was recently appointed to the chair of botany in 

 the newly created Mexican University.
