PREFACE 



IN the following manual I have endeavoured to give some 

 account of those portions of Bacteriology which are of 

 especial interest in clinical medicine and hygiene. The 

 preparation of tissues, methods of culture, descriptions of 

 pathogenic organisms and their detection, the examina- 

 tion of water, etc., have therefore been given at some 

 length. As it would be impossible in the space at my 

 disposal to include everything relative to the subject, a 

 selection has had to be made, and such details as the 

 celloidin method, Loffler's stain for flagella, the strictly 

 animal parasitic diseases (with a few exceptions), etc., 

 have, among others, been omitted. 



At the end of the sections dealing with the pathogenic 

 organisms which attack man, some directions have been 

 given for the bacteriological clinical diagnosis and exami- 

 nation, but these are in no way exhaustive ; in fact, it 

 would not be possible in a short work to give a scheme 

 of examination which would cover every case. These 

 directions will also render the book of service in the 

 laboratory, while I venture to hope that the details given 

 in the Appendix on the use of the remedies and diagnostic 

 agents of bacterial origin may be of value to the 

 practitioner. 



I have to thank ME. PEYTON BEALE, DR. LAMBERT LACK,
