buildings, the sudden prostration, the promptitude of certain re- 

 coveries and the favorable results of the iodine mammary in- 

 jections. The presence of sugar in the urine, most abundantly 

 in the worst cases, implies a profound disorder in glycogenic 

 centres (medulla, liver), and primarily no doubt in the bulb. 



Lesions. These are exceedingly variable in successive cases. 

 Congestion and effusion in the meninges, cerebral or spinal, in 

 the rete mirabile and choroid plexus have been often noticed, and 

 exceptionally clots of extravasated blood. In certain cases con- 

 gestion and pink discoloration of portions of the brain sub.stance 

 (cerebral convolutions, bulb, ganglia) with marked puncta vas- 

 culosa, are found, while in others the greater part or the whole 

 of the encephalon is anaemic. The puncta in such cases, large 

 and dark, on the surface of the section, promptly enlarge until 

 they may form distinct drops. 



In the Inng-s areas of collapse, and of dark red congestion and 

 infiltration are common, mostly as the result of the entrance 

 of alimentary or medicinal matters into the bronchia owing to 

 palsy of the pharynx. Such materials can be found in the 

 bronchial tubes. 



The third stomach and the large intestine may be impacted, 

 the contents more or less baked and gloss}^ on the surface, and 

 coincident congestions of the mucosa are not uncommon. In 

 some instances, however, the contents are soft and pultaceous 

 and the absence of mucous congestions is remarkable. 



The womb rarely shows characters differing from the condition 

 which is normal to the first few days after parturition. 



The blackness and thickness of the blood has been noted by prac- 

 tically all observers. This is partly the result of its density, but 

 doubtless also of the undetermined toxins which are operative 

 in the disease. 



Y&\\o\\'\'a\\ gelafinoid exiidates have been found in the subdorsal 

 and sublumbar regions, as well as the cranium and spinal canal. 



Glucose appears to be constantly present in the urine, and in 

 excess in the more violent and fatal cases: from i.iy grm. per 

 litre in slight cases to 41.8 grms. in a fatal one (Nocard). Al- 

 bumen may be present, though probabh' only when local inflam- 

 mation has supervened. 



Symptoms. The conditions of the attack should be noted.
