TYPHOID FEVER; OR, CONTAGIOUS INFLUENZA IN

“localized, the lungs are dense, compact, friable, tearing easily 
‘and having a granular fracture. On a smooth cut a large 
‘‘quantity of serum flows. There is also the red coloration with 
small bluish tints. By a microscopic examination the evolution 
“o the lesion can be followed, and the completely hepatized 
‘‘parts studied. Besides the infiltration of the partitions we 
I,' ° Und m the vesicles the changes of pneumonia; that is to say, 
Jan amorphous exudation containing globules of pus. These 
“capillaries are seen greatly distended, and around them a large 
“quantity of liquid, forming in mass a yellowish clot interposed 
“ between anatomical structures. On the periphery the anatomi- 
“cal interspaces are markedly distended by this granulous mass. 
eurisy may be added to the pneumonia or exist alone; in 
“either case the changes developed upon the pleura, with more 
“or less extension, does not essentially differ from those of an 
ordinary inflammation of this membrane. Finally, there is in 
“the lungs stagnation of blood with a large serous infiltration. 
‘‘Sometimes, although the lesions of pneumonia may be but 
“slight, death speedily ensues, pulmonary inflammation having 
“ led to gangrene. This seems difficult to explain. Small <r an _ 
“grenous, slate-colored, grayish foci are often found, havinc 
“ a putrid and infectious odor. In this case septicaemia has com- 
“ plicated the typhoid fever, because the mortified lungs putrefy, 
and there is speedy reabsorption of the septic elements and 
putrid infection.”

Vhen there are other localizations, the changes found upon 
post-mortem examination vary with the complication. I have 
never seen a fatal termination in those cases in which the 
podophyllous structure was involved. These cases of this com¬ 
plication in my practice made good recoveries after several 
months of idleness, without any noticeable changes in the 
structure of the hoof; therefore, a post-mortem examination 
would not have shown any thing more than a congestion of the 
podophyllous structure, with perhaps capillary hemorrhage on 
the surface. 
When there is localization upon the brain and spinal cord,
