The spleen did not present any characteristic appearance. 



The intestines were more or less hyperaemic, but of all the dozens 

 of cases examined — rabbits fed as well as inoculated — I have 

 only once met with a severe inflammation of the small intestine, 

 the contents of which consisted of blood-stained liquid slimy masses. 

 This was in the case of a vigorous, full-grown rabbit, fed at noon, 

 February 19th, 1889, on cabbage-leaves and 2 ccm. of fresh broth- 

 culture, and found dead at 7 a.m. next day."^ 



The rectum, or lowest portion of the large intestine, showed 

 nearly always normal-looking faecal masses, balled as usual ; it 

 was only rarely that its contents were not in the shape of isolated, 

 well-formed " spheroids," but in that of soft, more or less coherent, 

 greenish material. 



Very frequently the rabbits, soon after death, had the nostrils 

 covered with froth, which was stained with blood once. On the 

 other hand, when the dead rabbits were kept for some time, in 

 warm weather, undisturbed, in an open, place, a blood-stained 

 discharge from the nostrils was noticed repeatedly. 



In conclusion, I may add that in the cases of inoculation, the 

 seat of inoculation showed, as a rule, a slightly hj»morrhagic and 

 gelatinous oedema. (One remarkable exception is that of a rabbit 

 already mentioned above, as living two days after inoculation (see 

 also p. 552) ; other noticeable excei)tions are given by rabbits pre- 

 viously treated (see pp. 523-525, 529, 530). 



The absence, as a rule, of hsemorrhagic exudations into the in- 

 testinal canal, and, as a standard, of diarrhoea proper, in rabbits 

 treated with chicken-cholera bacteria, either by means of feeding 

 or of inoculation, forms a fundamental difference from what we 



* Haemorrhage of a different character took place in a pregnant doe, 

 which formed one of two fresh rabbits placed in a wire-bottomed hutch with 

 one which had been given 2^ ccm. of virulent broth-culture (conf. p. 534). 

 The doe, which was to all appearances in the end of the first, or the beginning 

 of the second week of gestation, died from "chicken-cholera" by "contact," 

 in less than 64 hours after being put in the hutch. Part of the fcetuses 

 were found to have been aborted under severe hcemoi^rhage.
