with oil of turpentine. Cauterization is also adopted 

 with success. Before treatment the head should be 

 bathed in warm water and sofc soap, and any of the 

 crusts should be carefully removed, care being taken 

 to prevent bleeding. The runs in which the birds 

 have been living should be cleansed with some of the 

 numerous disinfectants. 



C. Further Protozoan Parasites. 



Other Protozoan parasites found in the Fowl are 

 as follows : — 



Trichomonas Eberthi : this flagellate is found in the 

 glands of Lieberkiihn of the fowl's intestine, but not 

 sufficiently to cause any serious disease. 



Coccidium tenellum ( = Ricolto?) is also found in 

 the intestines in some numbers. 



Gregarlna actum intestinalis. — This was observed 

 bv Rivolta in the submucous connective-tissue of the 

 intestines, in thQ form of oval, globular cysts, filled 

 with pseudo-navicellae (spores). This protozoan 

 appears sometimes sufficiently abundant to produce 

 severe epizootics, causing violent diarrhoea and 

 otten death. This possibly is the same as the 



Eimeria dubia, described by Railliet in 1892. 



A Sarcocystis has also been found in the muscles. 

 For others see Appendix.
