RECENT INVESTIGATIONS OF SMUT FUNGI AND SMUT DISEASES 
AN ADDRESS DELIVERED BEFORE TEE SOCIETY OF AGRICULTURISTS OF BERLIN 
FEBRUARY 17, 1888. 
By Dr. Oskar Brefeld, 
Full Professor of Botany in Munster in TV.

Erwin F. Smith.] 
( Continued .) 
As early as 1884 I began to make infection experiments on host fdants, , 
but soon, on account of the great number of details involved and the 
unimproved condition of my eyes, I was convinced that I could not carry 
through the experiments without assistance. Only upon my entrance 
into the Ministry of Public Instruction and transfer to Munster in 
Wesen was the help of an assistant in Mycology willingly granted me. 
This I had previously done without, having requested it of the Forest 
Department of the Ministry of Agriculture and been refused, although 
it was desired only as a compensation for my eye lost in direct govern¬ 
ment service. With this help, which I secured in the person of Dr. G. 
Istvanffi, privat docent in the University of Klausenburg in Hungary, 
I was able to bring the experiments to a relative conclusion.
