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 Heydeureich the micrococcus of Pende's ulcer 

 (Micrococcus Biskra) ; while the Streptococcus contagiosae 

 coryzse ec[uorum 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 Itlue (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 ' 

 have been added. They are finally brought once more 

 into alcohol, and may then be submitted to examination.
