 It IS generally admitted that five worker-cells measure about 

 a linear inch, or twenty-five cells to the square inch, but this is

 ber in a square inch is a trifle over twenty-seven. Drone-cells 

 number about eighteen, in the same area.

L'Abbe Collin measured the average dimensions of the cells 

 veiy carefully, and the measurements given in his work (Paris, 

 1865) are about the same as those given above.

As bees, in building their cells, cannot pass immediately 



from one size to another, they display an admirable sagacity 



in makina" the transition bv a set of irregular intermediate
