The plug is pushed part way down the test-tube con- 

 taining the culture. The cotton is then partly saturated 

 with strong pyrogallic acid water (equal bulks of water 

 and acid). Sodium hydrate solution (i NaOH, 2 water) is 

 then pipetted on, and the tube immediately plugged air- 

 tight with a soft rubber stopper. The media should con- 

 tain I percent glucose. It should be fresh, and its reac- 

 tion not more acid than + 15. It may be used for fluids, 

 or roll cultures, and other forms.
