180 Insect Architecture. 



and the Hischocyttarus. But, we find that all the cells are 

 boldly angular, and that the angles are just as sharp on the 

 exterior of each cell as on the sides which cement the cells 

 together. It is clear that the bold lines and decided angles 

 of these cells cannot have been produced mechanically, and 

 that they must have been intentionally formed by the 

 insect architect. 



[One single cell, such as is here shown, is sufficient to 

 overthrow the theory of "equal pressure," by which insects 

 were deprived of all mechanical skill, and supposed to labour 

 like so many animated machines, without caring or knowing 

 anything about the work on which they were engaged. 

 According to the equal pressure theory, each of these cells 

 would have required six similar cells around it before it could 

 have assumed the hexagonal form, and yet we find that a cell 

 which is only connected with its neighbour by one side, has 

 its other five sides angular, and with the angles boldly defined.]
