OTHER MICROBES OF PUS 221 



tains the corresponding micro-organisms, e.g. Bacillus 

 anthracis and the bacillus of tetanus ; but besides these, a 

 considerable number of other microbes have been found 

 which have the power of originating suppurative processes. 

 Thus Weichselbaum discovered the Micrococcus intracellu- 

 laris meningitidis ; Neumann and Schaffer the Micrococcus 

 meningitidis purulentae ; Becker the Micrococcus osteomyeli- 

 tidis, and Heydenreich the micrococcus of Pende's ulcer 

 (Micrococcus Biskra) ; while the Streptococcus contagiosae 

 coryzse equorum was detected by Schiitz in suppuration 

 occurring in animals, and Pfeiffer found in the abdominal 

 cavity of a guinea-pig which died spontaneously a tenacious, 

 puriform exudation consisting of a pure culture of Bacillus 

 capsulatus. 



Some of the methods invented by Unna for staining 

 micro-organisms in cutaneous abscesses (see p. 90) are 

 excellently adapted for showing those in pus. The follow- 

 ing process may be especially recommended : The cover- 

 glass preparations are stained in carmine, transferred for 

 two minutes to borax methyl blue (1 part each borax and 

 methyl blue to 100 of water), rinsed in water, and placed in 

 alcohol to which a few drops of Spiritus saponis kalini l 

 have been added. They are finally brought once more 

 into alcohol, and may then be submitted to examination.
