naphtol will retard the disease, but most bee-keepers believe that it is not a sure remedy.
BLACK BROOD
This appeared in New York so frequently that it was called the New York bee-disease. It was differentiated from foul brood by Dr. Wm. R. Howard, of Texas, who found the bacillus and described it. The chief way of telling it from foul brood is that the contents of the body of the dead larva is jelly-like, instead of gluey. However, Dr. Veranus Moore and Dr. G. Franklin White, of the New York Veterinary College at Cornell University, worked upon this disease for some time and, in 1903, reported that the bacillus of this disease is alvei and identical with that discovered and disscribed by Cohn as the cause of foul brood.

This disease of the brood differs from the others in that the body-contents of the dead larva are watery and that no peculiar stench in the hive emanates from them. Neither is it so contagious as foul brood, though it may seriously cripple an apiary, if not checked. The remedy for foul brood is applied with success to colonies suffering from this disease.
DIARRHOEA
This disease is part of the difficulty of wintering. It is induced by the bees' habit of retaining waste matter in the body until they can fly out of the hive,
