INTRODUCTORY 
The reproductive mechanism of the male honey-bee has been 
so often and so variously studied that one feels called upon to 
state at once the occasion for its further investigation. 
The following study developed out of a series of unsuccessful 
attempts at the artificial fertilization of queen bees. Through 
a number of seasons this had been attempted by the methods 
which have been described by others as well as with newly devised 
apparatus. Two general classes of attempts were made. In 
the first, queen and drone were held in juxtaposition and the 
extrusion of the drone’s organ brought about by pressure on the 
abdomen. In the second class of experiments, the seminal fluid 
of the drone was dissected out and injected with a pipette into
