Il. STAINS AND REAGENTS USED IN THE 
STUDY OF BACTERIA. 
I. Simple Anilin Stains. 
Prepare saturated alcoholic solutions of gentian- 
violet, methylene-blue, thionin-blue, basic fuchsin, 
saffranin, or Bismarck-brown,’ by adding sufficient 
stain to absolute alcohol to make a saturated solu- 
tion, and leave some undissolved stain at the bot- 
tom of the vessel. T’o these stock solutions alcohol 
may be added from time to time, taking care that 
some undissolved stain always remains. When re- 
quired for use add 5 c.c. of the saturated alcoholic 
solution to 95 c.c. of distilled water, and filter. 
1Use the anilins prepared especially for microscopic 
work by Griibler.
