On the impkegmation of the eggs of the Queen. 



Tt would seem, from recent discoveries, that the spermato- 

 zoa do not simply come in contact with an egg, in impreg- 

 nating it, but actually enter into it, through a small opening. 

 In applying this discovery to bees. Prof. Siebold, of Germany, 

 dissected a large number of worker-eggs, and found, in such 

 as were not too much mutilated for proper examination, 

 from one to three spermatozoa, while in dissecting drone- 

 eggs, he could not find the slightest traces that they had 

 been impregnated. 



Dr. Donhoff reared, last Summer, a worker larva, from a 

 drone-egg which he had artificially impregnated. I attempt- 

 ed this experiment, irj 1852 ; but to ray great disappoint- 

 ment, the bees removed or devoured all the eggs thus treat- 

 ed, owing, as I then supposed, to their unwillingness to 

 raise workers in drone cells. By taking a piece of drone- 

 comb in which eggs have just been deposited, and touching 

 some of them with a fine brush, dipped in the diluted semen 

 of drones, I believe that queens, workers and drones may be 

 raised from these eggs, if the precaution, is taken to give 

 them to bees having neither queen nor brood of any kind. 



To those who deny that the human family could ever 

 have sprung from a single pair, on account of the great 

 physical diversities between the different races, I would re- 

 spectfully submit the fact, which has been demonstrated in 

 so many independent ways, that queens, workers or drones 

 may be raised from the same kind of eggs. The differences 

 between them, in size, shape, color and instincts, are con- 

 fessedly much greater than any between the various races "of 

 men ; and yet, in the one case, the changes are all produced 

 in a few weeks, while in the other, they may have had 

 many hundreds of years, for their gradual development.
