These imperceptible "sticks" break successively into 

 several parts, every one of which forms a colony of spores, 

 that pass through divers shai)es before developing into new 

 bacilli. We can judge of the promptness of their repro- 

 duction, and of their minuteness, when we read in Cheshire, 

 that a dead larva frequently contains as many as one billion 

 of these spores (28). 



788. In the Bulletin Agricole du DSpartement de I'Aube, 

 Mr. Brunet narrates the experiments made by Mr. Marcel 

 Dupont, to breed the bacilli of foul-brood. Knowing that 

 Pasteur used beef-broth in this kind of experiments, Mr. 

 Dupont filled three glass-tubes with unsalted beef-broth, pre- 

 pared according to the directions given by Pasteur, and after 

 sealing and boiling them, to kill any living organisms that 

 might have existed inside, he introduced into two of them, 

 with a fine needle, a small quantity of a liquid, in which 

 particles from the body of a diseased larva had been dis- 

 solved. One week after, the broth in both of these tubes, 

 was cloudy and full of bacilli, while the liquid, in the third 

 tube, had remained clear and unchanged. 



789. Description. As we have never seen a case of 

 bacillus alvei, we will borrow from those who have been more 

 "lucky" (?) than ourselves, a description of the disease, 

 for its detection in hives, and the remedies recommended 

 by the best authorities. 



" In most cases the larva Is attacked when nearly ready to seal 

 up. It turns slightly yellow, or grayish spots appear on it. It 

 then seems to soften, settles down in the bottom of the cell, in a 

 shapeless mass, at first white, yellow, or grayish in color, soon 

 changing to brown. At this stage it becomes glutinous and ropy ; 

 then, after a varying length of time, owing to the weather, it 

 dries up into a dark coiTee-coIoi-ed mass. Usually the bees make 

 noattemptto clean out the infected cells, and they will sometimes
