ditions, the queen cannot be readily induced to lay in drone- 

 cells. Our conclusions on this point differ from those of 

 j\li-. Kddt. We think that the ciueen prefers worker-cells to 

 drone-cells, because the fecundation of the eggs by the action 

 of the muscles of the spermatheca probably gives her a pleas- 

 ant sensation, which she does not experience in laying drone-

toO. Some veiy prolific queens occasionally lay drone- 

 egL;s in worker-cells. It may be due to fatigue. This will 

 readily be admitted when we consider the number of eggs 

 laid in one day. (98.) 



151. Dzierzon found that a queen which had been refrig- 

 erated for a long time, after being brought to life by warmth, 

 laid only male eggs, Avhilst previously she had also laid fe- 

 male ei;gs. Berlepsch refrigerated three queens by placing 

 them thirty-six hours in an ice-house. Two of thfem never 

 revived, and the third laid, as bet'ure, thousands of eggs. 

 but from all of Ihem onlij males iverc evolved. In two in- 

 stances, Mr. ]Mahan has, at our suggestion, tried similar ex- 

 periments, and with like results. A short exposure of a 

 queen, to pounded ice and salt, answers every purpose. The
