Seeing that the foul-brood bacteria must necessarily kill all brood the digestive canal of which is inoculated by the act of feeding, it appears to be absolutely useless to en- deavor to cure these larva;, as all their tissues are rapidly invaded by the virulent granulations into which these bac- teria resolve themselves. (I employ the word granulations purposely in preference to the term spores, which is used by several writers. I cannot bring myself to believe that true sporulation, similar to that observed under certain condi- tions in bacteria of anthrax, and in that of blood from spleen, really takes place in foul brood.) "3. Adult bees, whose digestive canal is infected by the foul-brood bacteria, may frequently survive for a con- siderable period. Some even, owing to special circum- stances, seem to resist the virulent stage of the malady. We must, therefore, direct our efforts to the digestive canal of the worker-bees, the feeders of the queen, if we desire to attack at its source the evil which maj- spread with light- ning rapidity among the rising generation of larvK, which is the sole hope of the colon)'. "IV.—The treatment, then, ought to be internal and as energetic as our little patients are willing to allow. Exter- nal treatment, by means of fumigations or sprayings of any kind, are (I do not for one moment deny) also helpful, since these methods contribute largely to the disinfection of the hives, combs, and tissues of the bees, etc. It is even possible, under certain circumstacues, to succeed in dimin- ishing the virulence possest by the bodies of the larva? after death during the process of desic
