All Dimensions in mm,
D/W is the ratio of Drone cell size to Worker cell size,
ESW is Excluder Slot Width,
I have used ?... symbols where data is unknown (to maintain tabulation),
Lower case letters are expanded as notes following the table.

Notes
a, 32mm to 38mm is actually used.
b, in USA (Taber & Owens, 1970).
c, this is the gap in square mesh coffee wire, 0.58mm diameter wire on 5mm
pitch.
d, Indian Standards Institution (1976).

I add a note that this is data from "recent times" (confirmed by the
author).

It seems strange that the only incidence of cell sizes above 5.0mm is in
areas of the world that some of us consider to have been under the influence
of artificially large celled foundation for the last 100 years.

I apologise that the table is not as prettily laid out as the original...But
plain text Email format is not as flexible as some other systems.
