From Table V it can be readily seen that the conidia vary 
in length from 27.5 to 69.49 microns, and in width from 21.5 
to 41.49 microns. In length the majority of the spores falls into 
the classes between 39.5 and 53.49 microns, the largest number 
falling in classes betv/een 43.5 and 53.49 microns. In width the 
majority falls into classes between 27.5 and 37.49 microns, the 
largest number being in class 31.5 to 33.49 microns. 
Table VI presents the arrangement in classes of the ratios of 
the length to the width of the conidia.
