Fig. 10-7. A. The microfilariae that cause the 

 disease elephantiasis live in the blood of man 

 and can be seen in blood smears taken at 

 certain times of the day. The tiny worm is 

 clearly visible in this picture and its relative 

 size can be determined by comparing it to 

 the small irregular objects which are the white 

 corpuscles.
