bacilli over those found in the original sputum. The Ehrlich and the 

 Neelsen-Johne methods of staining were used. 



If the alkalized fluid were allowed to stand longer than two days, and 

 if more than fifteen drops of caustic soda were added, the number of bacilli 

 diminished. From these facts, it is naturally concluded that the non- 

 staining is due to the alkali, and the author recommends fjr his pro- 

 cedure the Neelsen-Johne method, as he found that Ehrlich's stain was 

 less reliable. The foregoing method is inapplicable for the demonstration 

 of Bacillus tuberculosis in tissues.
