lesions and aphthae of the intestines, and pyrexia : the muscular 
and nervous systems, the brain included, become exhausted 
by imperfect nutrition due to deficient capillary circulation 
dependent upon poisoning by retained secretions. Meantime 
the stomach and duodenum are incapable of performing their 
accustomed functions owing to determination to supply the 
loss entailed by the diarrhoea, and are unable to supply the 
fluids essential to nourishment and thus repair waste ; and 
unless relief is obtained, collapse speedily follows to fatal end¬ 
ing. Zootomy in such cases reveals the stomach and duode¬ 
num pale and flabby, or as the seat of violent inflammation ; 
and the ileum, jejunum, and ccecum denuded of epithelium, 
with haemorrhagic infarctions and general low inflammatory 
condition; and when the dejections are clayey or have been 
persistently colorless, usually will be found obstruction of the 
pancreatic duct. Hydrobilrubin, the coloring matter of the 
faeces, depends upon the mutual reaction of the biliary and 
pancreatic fluids. 
Again, from inanition and exhaustion, perhaps from pto- 
mainic poisoning, the poor creature falls into a state of stupor 
or coma, exhibiting puffy under-eyelids, congested half-closed 
eyes, cold nose and legs, slow breathing, weak pulse, and the 
flanks and belly are retracted. This frequently occurs in in¬ 
noxious scourings when the discharges are abruptly checked, 
and affords in such case indubitable evidence of toxic produc¬ 
tion, due to remedial interference.
