were examined for comparison ; for the objection might certainly 

 have been raised, that this queen might have laid nothing but 

 barren eggs, as, being already weakened by age and near her 

 death, she might have had no more sperm atozoids in her seminal 

 receptacle. Nevertheless, many of these eggs contained seminal 

 filaments ; they were the twenty-seven eggs already mentioned 

 by me, — namely the sixteenth to the forty-second eggs. 



To this result of my Seebach investigations, which proves the 

 correctness of Dzierzon's theory by direct observations, I may 

 also add that Herr von Berlepsch has lately informed me by 

 letter, that this queen subsequently, after my departure from 

 Seebach, also laid female eggs, from which workers were deve- 

 loped, but she herself only died on the 19th September, 1855.
