be found. While if death occurred several weeks 

 or months previously, the capping of the cell will be 

 found entirely black ; on opening it, only a small por- 

 tion of dry animal fiber will be found at the bottom 

 of the cell. If the disease has caused death several 

 months previously, occasional cells are found of a dark 

 color, and so coated over with wax or propolis as to 

 make them quite oval, and bees do not like to cluster 

 on them. On opening these cells, they are found to 

 contain a small portion of inorganic matter, and to 

 emit a disagreeable small, somewhat resembling that 

 from carrion. 



This, to a person familiar with it, is sufficient evi- 

 dence of the presence of the disease. It is possible 

 that where a limited number of the pupa die from 

 disease, and the bees discovering the same at once 

 seal them densely with wax or propolis, the spread of 

 the disease may be prevented for a time. Even the 

 virus contained in honey may be carried in and sealed 

 up, to remain for a considerable length of time, and 

 then fed to brood, causing their death, as well as a 

 farther spread of the disease. 



Chilled brood, as has before been stated, will most- 

 ly have the capping of the cells raised ; on opening 

 them, the young bee is found to be dead, but will 

 show the head and other members nearly developed. 



Pupa, if dead from chill, at first has a dark streak 

 through its center ; when decayed, it turns of a gray 

 color, arid watery, with sediment not usually ropy. 

 Chilled larva turns nearly black soon after death.
