FOREWORD 



With the rapid growth of Parasitology there is also a growing 

 demand for laboratory instruction in this field. The author's 

 greatest desire during the time that he has been engaged in 

 teaching this subject has been to place the work upon a good 

 systematic footing, giving it proper rank with other phases of 

 applied biology. The following exercises are based upon several 

 courses in Parasitology (now merged into two) that have been 

 given by the author at the University of California during the 

 past four years, including two summer sessions. Each exercise 

 has had careful testing in the laboratory and is practical. 



The aim of this Guide is to give the student a wide practical 

 view of the field so that he might have a fair grasp of the general 

 subject in its application to the health and well-being of man and 

 beast. The exercises are in sufficient detail so that the student 

 is enabled to continue work on some specific group or species if 

 he so chooses. 



The exercises are arranged to provide sufficient matter for a 

 laboratory session requiring from two and a half to three hours 

 for each. A number of the exercises are divided into two or 

 three parts, and this may be useful in cases where less time is 

 available. The two standard courses given at the University of 

 California upon which these exercises are based are Human 

 Parasitology (first half year) and Veterinary Parasitology 

 (second half year), each with three lectures per week and two 

 laboratory sessions of from 2> to 3 hours. 



The author wishes to gratefully acknowledge the very able 

 assistance rendered by Mr. A. B. Shaw, Jr., in the preparation 

 of this laboratory guide.
