3. " Teamster's mare, 5 years old. Ill three or four weeks. 

 The spleen was very much enlarged and honey-combed, with puru- 

 lent matter, and the lymphatic glands genei'ally inflamed." 



4. " Hack mare, 3 years old, foal at foot, ill about three weeks, 

 with a spleen in the same condition." 



" The small intestines in every case were healthy." 

 In two (Nos. 3 and 4) out of these cases Mr. Stanley preserved 

 some pieces of spleen and some lymphatic (mesenteric) glands ; 

 besides he secured in capillary tubes, which were afterwards closed, 

 samples of vein-blood, withdrawn from the living animal during 

 the height of the fever. All these specimens were handed to me 

 for examination from the Department of Stock, some time ago.. 

 I communicated my report to the Chief Inspector of Stock, but 

 being of opinion that the subject under notice might be of some 

 interest to members of this Society, and that a somewhat fuller 

 account published in its Proceedings, might help in either 

 identifying the disease as a possibly known one, or recognising it, 

 if not so, in case it should make its appearance elsewhere, I wish 

 to say what follows. 



The fragments of spleen and the lymphatic glands were — so I 

 was informed on inquiry — secured immediately after the death of' 

 the patients, and at once transferred to methylated spirits. About 

 three months having elapsed wlien I obtained for examination 

 these specimens, which were pretty well hardened, I did not think 

 it necessary to try to cultivate any micro-organisms out of them ;. 

 and I may as well state beforehand that the character of the micro- 

 organisms found in sections, did not admit of any positive result. 

 So I proceeded to prepare a series of sections, some time after 

 having changed the methylated spirits for absolute alcohol. 



1 shall speak first of the result of the examination of the 

 mesenteric glands. 



Sufiiciently and uniformly stained sections (for instance by 

 Loeffler's alkaline methylene blue or by bismarck brown) exhibited
