Tap water is recommended for dilutions. A 24-hour 

 agar surface growth furnishes the bacteria. They are 

 allowed to diffuse in a little of this sterilized water" iu a 

 watch glass. A drop or two of this is then placed ou the 

 clean slide or cover and spread as widely as possible with- 

 out use of the needle. The excess is absorbed by blotting 

 paper. The dried film is not fixed by heat. The staiu 

 consists of tatmic acid i gram, potash alum i gram, dis- 

 tilled water 40 cc. To this is added 0.5 gram of night blue 

 dissolved in 20 cc. of absolute alcohol. The copious pre- 

 cipitate which results is carefully removed by filtration. 

 The fluid is then ready for use. Stain 2 minutes. The 

 flagella are blue, the body of the organism is not stained. 

 Longer exposures cause" precipitates. Counterstaiu for 

 the bod}- by exposure for i or 2 minutes to anilin-water 

 gentian violet. "I consider that the application of heat 

 and the spreading of the film with the needle are very 

 fatal to good results in flagella staining."

 The author's plan for staining capsules is as follows : 

 Pass the dried covers three times through the flame, and 

 then expose from one to several minutes in i per cent 

 acetic acid water. Remove from the cover by blowing 

 through a glass tube drawn to a point, aud dry in ail- 

 quickly. Then expose iu a saturated solution of'anilin- 

 water gentian violet for a very few seconds, wash iu water 

 aud examine. The exposure to the gentian violet should 

 be barely long enough to staiu the capsule without stain- 

 ing the interior protoplasm.
