COMPARATIVE WEIGHTS OF NATURAL COMB AND COMB ON ARTIFI¬ 
CIAL FOUNDATIONS. 
There is a third method of studying the effect of foundations 
upon the resulting comb which, to my mind, gives the most con¬ 
vincing evidence. By this method pieces of natural comb and 
comb on different kinds of foundation were cut into blocks of known 
area and carefully weighed. Then the cell walls were removed 
from the midribs and the weight of these two portions determined 
separately. Then the weights of the midribs and cell walls of 
natural comb were compared with the corresponding parts of comb 
built on artificial foundations, and the midribs of the latter with 
their corresponding foundation midribs. In this way I was able to 
determine whether the cell walls or the midribs of comb on arti¬ 
ficial foundations were as light as in the natural comb.
