X FOWL ENTERITIS— NATURE OF DISEASE 91 



disease from fowl cholera, I have called it fowl 

 enteritis. I have described the nature and character 

 of the disease in the Centralblatt filr Bacteriologie 

 und Parasitenkunde, 1889, v. 21 and following; and 

 although the different size and scarcity of the bacteria 

 in the blood in the Orpington fowls was clearly- 

 pointed out, as also the difference in the appearances 

 at the post-inorte7n examination in fowl enteritis and 

 fowl cholera ; the remarkable and striking fact that 

 pigeons and rabbits were found insusceptible to the 

 disease, and other differences, were clearly stated, 

 yet some critics ventured to offer the opinion that 

 the Orpington disease, i.e. the fowl enteritis, is not 

 sufficiently well differentiated from fowl cholera to 

 be declared not to be such. To this I can only 

 say, — and in this 1 am sure every pathologist and 

 bacteriologist who has any personal knowledge of 

 fowl cholera will agree with me, — that those critics 

 either are not sufficiently, certainly not directly, ac- 

 quainted with fowl cholera, or they have not read my 

 statements as regards the Orpington disease, or both. 



Other equally striking differences are noticed be- 

 tween the two diseases if the cultures obtained from 

 the Orpington fowls are studied.
