if it can be preserved against bee moth. 
Drones. See Mater Regia. Huber speaks of queen refusing to lay
worker eggs in drone cells. At first this will seem to overthrow the theory of
Dzierzon, but it does not necessarily. Construction of queen cells and laying of drone
eggs go together, indicating their connection. If the queen can lay drone eggs or not
at choice, she would not lay them in the circumstances in which Huber put her, for she
would have no intention of swarming. 
Fertile Workers. Huber found such, reared in cells adjoining those of queens
reared artificially, he did not decide how they were impregnated. 
Obtain them as he did, confine them to hive, and see if they will lay eggs. 
Examine whether they have a spermatheca, and whether those that lay eggs are
impregnated. Examine microscopically the food of young queens and the
food of other larvae. Try it if possible by chemical tests. 
Dzierzon found fertile workers or drone mothers, he was likely to do this because
he raises so many artificial queens. He believes that without impregnation
they are able to lay the eggs of males. Let some of their eggs be touched
with the male semen. 
 (April 23, 1861) Can we by experiment prove what causes queens to lay eggs. 
Do the bees give them feed, or have they a self power. When a queen does
not meet the drones she will long lay no eggs, 48 hours or less after she
meets drones, can we give reason, so of diminished size about swarming time, then
try to put a queen as soon as she comes back from drones with only a
few bees, and no pollen, another with honey but no bees, and let a
third alone. As soon as latter begins to lay, send all three to Dr. 
Leidy for dissection. (24) One with pollen and honey and no bees, one
of same age shut in her hive so that she could not go to meet the drones.
