30 THEORY AND PRACTICE 



Organization — the inflammatory deposits (the proliferating 

 cells, coagulated albumen, fibrin, etc.) become permanent by the 

 growth of the connective tissue cells, new formation of blood 

 vessels, and the penetration of new nerves, the previous seat of 

 inflammation becoming a permanent part of the animal. 



Disorganization — a degeneration and liquefying of tissue. 

 In case of resolution, the softening, liquefaction and absorption 

 occur, leaving the part perfectly healthy. 



As a last result of inflammation we may get gangrene, — 

 both moist and dry. It will not differ from that of active con- 

 gestion, except that it will be more pronounced and will occur 

 more frequently. 



DEATH. 



The time comes when every animal must die. With the vet- 

 erinarian there is little sentiment about this event. It is im- 

 possible to define it; if we say that it is the cessation of life the 

 question immediately arises, What is life? But we do not know. 

 However, we consider animal to be a machine dependent upon 

 three vital functionating systems: 



1. Hydraulic system, — that including the 



heart and blood vessels. 



2. Pneumatic system, — that made up of 



the respiratory apparatus. 



3. Nervous s^^stem, — that composed of the 



brain, medulla, spinal cord and 



nerves. 

 In general, we may say that death occurs by iriferniption 

 of one of these three systems every time.' Interruption of the 

 function of one will cause death, without reference to the other 

 tv/o. These three are the vital means of sustaining life, and if 

 one ceases to functionate, the other two will also. 



Some pathologists record a fourth channel through which 

 death may occur, — the blood, the poisoning of which (nec- 

 raemia) results in death. But this in turn acts upon the nervous 

 system to which in such a condition the cause of death may be 

 referred.
