THE DETECTION OF THE MALARIA 

 PARASITE 



Examining The Film 



After staining and drying, the film is ready 

 for examination. No Canada-balsam or coverglass 

 need be applied. A drop of cedar-wood oil is 

 placed upon the film and the oil immersion lowered 

 into it. 



After the examination is completed, if it be 

 desired to keep the film, the cedar oil is dissolved 

 off by dropping a little xylol over the film and 

 allowing this to drain off and then to dry. After 

 drying, the film can be put away and kept in- 

 definitely. If not needed the slide is placed on 

 one side with others and eventually cleaned. 



To Clean Dirty Slides 



1. Rub with turpentine (benzine or xylol) to 

 remove any adherent oil. 



2. Wash with soap and water. 



3. Rinse in water. 



4. Dry. and rub well with a clean cloth.
