PREFACE 



The exercises and descriptions in this laboratory manual are 

 intended primarily for students in General Bacteriology. The 

 work outlined can be covered in an eighteen week period having 

 two two-hour laboratory periods a week, preferably at intervals 

 of two and five days. The course offered at this institution includes 

 two one-hour lectures a week. The lectures and laboratory work 

 are planned as far as possible to parallel and supplement each 

 other. 



Students in this course do not prepare their culture media or 

 sterilize their glassware for we feel that the beginner, in bacteriology 

 can use the limited time more advantageously in other directions. 



The description of bacterial species includes some pathogens 

 but only non-pathogenic organisms are used in this course. 



The glossary of bacteriological terms appended will be found 

 helpful to the student beginning the study of bacteriology.
