We are indebted to Huber for the discovery of the use made by the bees of pollen.
My experiments do not corroborate this theory, but tend to confirm the views of Huber, and to show the absolute necessity of pollen to the development of brood.
After Huber had demonstrated that wax is secreted from an entirely different substance, he was soon led to conjecture that the bee-bread must be used for the nourishment of the embryo bees.
