ped by pressure. Capillary haemorrhage may, however, be 

 active or passive, according to its origin. If the blood, 

 modified in quality, exudes or transudes through the coats of 

 the vessels, which have only very partially given way, the 

 haemorrhage is said to be passive. This occurs in many dis- 

 orders in which a blood poison is in operation. Active capil- 

 lary haemorrhage is always the result of injury. In passive 

 haemorrhage you must treat the blood disease, or apply cold 

 water to the part where the oozing occurs. In active 

 haemorrhage, stiptics, such as sulphate of iron, tincture of 

 matico, alum lotion, tincture of the sesqui-chloride of iron, 

 &c., may be applied, favoured by rest and pressure.
