Grew's statement was fully accepted, and then 
only because the great Linnaeus assured the 
world that it was true. But about fifty years 
later another botanist in Germany, Sprengel, 
made the discovery that the flower could not 
be fertilized as these botanists had claimed, that 
jxllen 
in many blossoms the pollen could not fall on 
the stigma. 
Sprengel knew that this pollen must reach the 
stigma, but showed that in most flowers it could 
not do so by itself. He saw that insects were 
always working in the flowers, and that their 
hairy bodies were generally covered with pol- 
len, and in this way pollen grains were contin- 
ually carried to* the stigma, as they could easily 
be in these two blossoms shown at Diagram B. 
Sprengel then announced to the world his the-
