PREFACE. 



MANY of the duties of the nurse require a knowl- 

 edge of the principles of bacteriology in order to be 

 performed intelligently. It is difficult, however, for 

 anyone instructing nurses, to decide just how much of 

 the subject to attempt to teach. 



The basis of this book is the lecture notes that I 

 have used during the last eight years in teaching the 

 nurses of the Samaritan Hospital Training School. 

 In incorporating them into 1 book form I have en- 

 deavored to present clearly and in simple language 

 that portion of the subject essential for the nurse to 

 know. A few blank pages have been inserted at the 

 end of each chapter for the convenience of the student 

 in adding useful notes from time to time.
