hundred being present, their long axis being generally parallel with 
the duct. 
In Experiment No. 36, malignant tertian sporozoites were found 
after the eleventh day in the red-stained hyaline salivary acini on 
both sides of the body in large numbers. Very few in the faintly 
stained, larger vacuolated acini, and none in the acini containing 
colloid globules; but the duct of the latter contained sporozoites, 
which were generally matted together.
