Bees were confined to their hive without any pollen, after being supplied with honey, eggs and larvae.
A fresh supply of brood was given to them, with an ample allowance of pollen, and the development of the larvae then proceeded in the natural way.
That, June 24, 1911, at Eton, Bucks, England, the ground was found covered with masses of jelly, the size of peas, after a heavy rainfall. We are not told of nostoc, this time: it is said that the object contained numerous eggs of "some species of Chironomus, from which larvae soon emerged."
