top cells are elongated, and sometimes smaller cells 
are built to fill up. In one of the combs mentioned 
above, the first row of cells was turned with its parallel 
sides to the top, all the other rows following in the 
same direction. The rows were slightly curved, and 
were inclined over the whole comb from right to left 
at an angle of 43°. 
To any one who carefully observes naturally built 
combs, the irregularity is most striking. Besides the 
small differences in size 
which we have mentioned, 
cells of different shapes fre- 
quently occur, and we have 
seen them with as few as 
three, and as many as seven 
sides. One of these is seen 
in Fig. 69, a, and another in 
Fig. 65, c. 
The illustration (Fig. 70) shows cells nearly square. 
These are from a comb we obtained in Canada

through the kindness of Mr. D. A. Jones. Several of 
the rows consisted of such square cells.
