EXHALENT SYSTEM. 159 



Q. What exhalents most frequently pour out blood? 



t/?. The mucous. 



Q. What are the evidences that these mucous haemor- 

 rhages are exhalations? 



/?. The mucous surfaces, though minutely examined 

 after death, show no ruptured points; pressure on the 

 uterus after death during menstruation exhibits an issue 

 of bloody drops, but no rupture can be seen; the womb 

 would exhibit a surface of cicatrices, if haemorrhages pro- 

 ceeded from erosion; the sudden translation of haemor- 

 rhages from one part to another, under sympathetic laws, 

 tend to confirm the doctrine of exhalation rather than rup- 

 ture; the causes of haemorrhage from rupture are so dif- 

 ferent from those of spontaneous haemorrhage; and lastly, 

 these accidental haemorrhages are not under the laws of 

 sympathy, as the spontaneous are. 



Q. What is the anatomical distinction between haemor- 

 rhage and inflammation? 



t/?. In inflammation the blood accumulates in the capil- 

 laries; in haemorrhage the blood passes out from (he arte- 

 ries l>y the exhalents. 



Q. Is it not probable that the irritation is differently 

 located in the two diseases? 



Ji. Perhaps it is seated in different vessels in haemor- 

 rhage and inflammation. 



Q. What proof have you that in active haemorrhage the 

 organic sensibility is altered? 



*fl. The previous symptoms of heat, pain, itching, show 

 that it is altered. 



Q. In passive haemorrhages how are the vital forces of 

 the exhalents affected?
