THE EFFECT OF AQUEOUS SOLUTIONS UPON THE 
GERMINATION OF FUNGUS SPORES.* 
Fe-L. STEVES: 
OBJECT. 
THE primary object in the work here related was to establish 
with some degree of accuracy the strengths of various solu- 
tions which are necessary to prevent the growth of fungus 
spores, 
The bearing of this question upon the relation of a fungicide 
to its efficiency is apparent, and from the wide use of these 
compounds it seems important that all knowledge possible 
should be gained regarding the principles underlying their 
action. 
Incidentally, new evidence bearing upon the theory of the 
hydrolytic dissociation of the molecule is adduced; also facts 
which may throw some light upon the structure of the cell wall 
PRELIMINARY. 
Before work bearing results could be practically undertaken, 
it became necessary to select the best manner of working, and 
the materials to use, and to become familiar with the sources of 
error most common.
