grains) will contain 4,166,666 laminse. Hence, | of an 

 ounce will contain 81,367 laminae. Now this quantity 

 was produced by 2,765 bees in six days ; so that the bee 

 requires for the formation of its 8 laminae (one crop) 

 about thirty-eight hours, which agrees very well with my 

 observations. 



The laminae, when formed, are as white as bleached 

 wax. The cells also, at first, are quite white, but they are 

 coloured yellow by the honey, and still more by the 

 pollen. When the cold weather comes on, the bees 

 retire to the hive under the honey, and live on the stock 

 they have accumulated. 



P. 54. Many believe that bees are* hybernating 

 animals ; but this opinion is quite erroneous. They are 

 lively throughout the winter; and the hive is always 

 warm in consequence of the heat which they generate. 

 The more numerous the bees in a hive, the more heat is 

 developed ; and hence strong hives can resist the most 

 intense cold. It once happened that I forgot to remove 

 from the door, which was unusually large, of a hive in 

 in winter, a perforated plate of tinned iron, which I had 

 fastened over the opening to diminish the heat in July; 

 and yet this hive came well through the winter, although 

 the cold was very severe, having been for several days 

 so low as 0. But I had added to this hive the bees of 

 two other hives ! When the cold is very intense, the bees 

 begin to hum. By this means respiration is accelerated 

 and the developement of heat increased. If, in summer, 

 bees without a queen are shut up in a glass box, they 

 become uneasy and begin to hum. So much heat is by 

 this means developed, that the plates of glass become 

 quite hot. If the door be not opened in this case, or if 

 air be not admitted, and if the glass be not cooled by the 

 aid of water, the bees are soon suffocated.
