2. The form whicli seems to be European foul brood lie refers to 

 as the "mild" form; and the other one, which seems to be American 

 foul brood, he refers to as the "virulent" form. 



3. In the "mild" form he finds Bacillus alvei and Streptococcus 

 apis, together with a few other species. 



4. In two instances he did not find Bacillus alvei present, but did 

 find Streptococcus apis. This condition he believes to be the "sour 

 brood" of Burri. 



5. In a few cases only ho reports difficulty in obtaining cultures of 

 Streptococcus apis on artificial media. 



6. In the disease (^bnerican foid brood) which is most common in 

 Germany, Maassen finds a species which he calls Bacillus hranden- 

 hurgiensis. 



7. In this disease he also finds Bacillus alvei generally associated 

 with Bacillus hrandenhurgiensis. 



8. In a few samples he found Streptococcus apis accompanying 

 BadUus hrandenhurgiensis. 



, 9. In his experunental inoculations, he obtained positive results 

 when Bacillus hrandenhurgiensis in eitlier the .vegetative or spore 

 form was fed to a healthy colony. 



10. He obtained negative results when healthy colonies were fed 

 cultures of Streptococcus apis, 



11. He failed to produce disease by feeding to tiie healthy colonics 

 dead brood containmg Streptococcus apis but no Bacillus alvei. 



12. He reports positive results when the spores of Bacillus alvei 

 were fed together with dead brood containing Streptococcus apis. 



Maassen, September, 1908. 



Maassen ^ pubUshed another paper m 1908. He reviews briefly 

 the history of the study of foul brood. An attempt was made to 

 learn of the distribution of the diseases in Germany. For this pur- 

 pose letters were sent to bee keepers m various parts of the country, 

 making inquiry into the disease conditions of the apiaries. Answers 

 were received from two States. He obtamed data, however, from 

 other sources which caused him to believe that foul brood is frequent 

 hi almost all of the German States. A review is then made of his 

 own investigations relating to foul brood.
