4 BACTERIOLOGY. 



chapter upon their classification, followed by a de- 

 scription of each species, more particularly of those 

 of pathological interest, with a detailed account of 

 the special methods of examination and of staining 

 employed for demonstrating the different species. 



In the Appendix a descriptive list of important 

 yeasts and moulds will be given, with any special 

 technique required in their case. Yeasts and 

 moulds are constantly encountered in the special 

 methods for examining bacteria in air, soil, and 

 water, and several are of interest in being, like 

 many bacteria, micro-organisms associated with 

 disease. A short account is also given of the 

 Flagellated Protozoa, which have been found to 

 occur in the blood of animals. To the pathologist 

 these are of interest owing, more especially, to the 

 discovery of closely allied micro-parasites in the 

 blood in cases of malaria. 



The special methods just referred to, with 

 description of the apparatus employed, and a 

 Chronological Bibliography, are also comprised in 

 the Appendix.
