Raymond Pearl and Maud Dewitt Pearl 423 
have accordingly determined this value for each of the combs, by dividing the 
measured area by the measured length. The values so obtained are designated 
as the "calculated heights." These measurements are given in Table I. The 
total number of combs included is 81.

3. The actual outlines of the combs studied are shown, somewhat reduced in 
size, in Plates I. to III. Combs 35 to 49 inclusive present a different appearance 
* The values tabled are the figures to the nearest whole number, obtained by dividing the area by the 
lengths.
