Hi Guys, >The figures that were observed and recorded in the period around 1880 would be good bets, but even then I would not put too much on their accuracy.... There's another factor to be considered when evaluating most historical measurement. Most beekeepers believed the concept that bees draw out only a single worker cell size. Just how did they find that perfect size cell? What criteria was used to select some comb and reject others? A specimen of fossilized honeybee comb was found in China. It would be interesting to see if the bees built a single size worker cell or whether the cell size tapers like all of the comb I've measured to date.
