So I've looked through the literature and I found a review article saying all of this and more. It was written by a group of respected physicians from American and French hospitals and it clearly supported the widely held belief that you should drink two to three litres of water a day.
This is a common occurrence to have your brood chamber become honey bound during the main nectar flow. A typical hive body will have a brood cluster in the middle and the outside frames will contain honey. A honey bound hive happens when brood begins to emerge, it is replaced with nectar.
Other inventors, notably FranÃ§ois Huber in 1789, had designed hives with frames (the so-called leafe or book hive), but Langstroth's hive was a practical movable frame hive, which overcame the tendency of the bees to fill empty spaces with comb and to cement smaller spaces together with propolis.
