and structures of the chest. When occurring in the cabdominal 

 cavity, death is usually the result of peritonitis. 



Sequelae of Strangles. — The most frequently occurrmg and 

 damaging results or sequehe of irregular strangles, and some- 

 times of the regular form, are those permanent structural 

 changes which follow chiefly as a result of that form where 

 the local diseased action is concentrated upon the larynx and 

 structures associated with it. There is often left, as the result 

 of an attack of this form, some textural change, either of the 

 lining membrane and interior structures of the larynx, or of 

 the surrounding and intrinsic muscles and their associated 

 structures. 



Changes in either of these situations tend to the production 

 of results precisely similar, viz., defective respiration. This dis- 

 turbed functional activity is ordinarily recognised by some 

 term taken from its audible manifestation, as roaring, 

 whistling, etc. 



By far the most serious sequelae or results of strangles, how- 

 ever, are pyogenic fever, pyaemia, and general blood-poisoning, 

 the result of absorption of certain decomposing or degraded 

 materials, the product of local inflammatory action — most pro- 

 bably puriform constituents or certain liquid inflammatory pro- 

 ducts. We speak of this infective process as 'pycemia when, in 

 conjunction with the fever, there are numerous secondary dis- 

 seminated abscesses in various organs ; and as blood-poisoning, 

 or septicemia, when, with the pyrexia, we have general and 

 marked disturbance of vital functions, but not necessarily ab- 

 scesses. There is, however, a great probability that no true patho- 

 losfical difference exists between the two named conditions. Both 

 pyo3mia and septicwmia result from the absorption of certain 

 infective substances from some foci of local inflammation. 



There is, however, a distinct difterence between p>ycemia and 

 abscesses, the result of irregular forms of the disease. 



Generally speaking, those large, well-formed abscesses or 

 collections of pus seen in the lymphatic glands, in the region 

 of the neck and limbs, ought rather to be regarded as belong- 

 ing to the latter than to the former cases. 



When pycamia is encountered as associated with or rather 

 resulting from strangles, it is following, not concomitant with, 

 the occurrence of the primary abscesses ; or at least it rarely
