CUTANEOUS HEMORRHAGE: BLOODY SWEAT: 

 H^MATIDROSIS. H^MATOPEDESIS. 



Forms of cutaneous haemorrhage ; in specific diseases ; in parasitism ; in' 

 insect bites ; in congestions of sweat glands ; in deranged innervation ; in 

 hEembphifia. Section of sympathetic. Salt on sciatic. Hysteria. Sclerosis 

 of cord. Inflammation. Symptoms: drops, crusts. Haemorrhagic nodules. 

 Treatment : styptics, cold, ice, snow, tannin, matico, iron chloride, alum, 

 gelatine, atropine, ergot, lead acetate, quinia. Gravitation. 



The escape of the blood by the skin is seen in a variety of 

 morbid conditions, due it may be to profound changes in the 

 blood and capillary walls, as in petechial fever, anthrax, scorbutus,, 

 septicaemia, swine erysipelas, etc. , in which this is only a sub- 

 sidiary phenomenon of a general disorder : — to the presence of- 

 parasites (Filariahsemorrhagica, )intheskin : — to insect bites :- — 

 to violent congestions implicating the sweat glands (bloody 

 sweat): — or to deranged innervation of the part as in cases of 

 trauma of the sympathetic or sciatic nerve, or disease of the 

 nerve centres. It may further be a manifestation of haemophilia 

 in which any slight lesion becomes the occasion of persistent 

 haemorrhage. 



Cases that appear in the course of specific contagious diseases 

 and those dependent on filaria will be considered under these 

 headings, and we may confine our attention here to the forms of 

 sweating and oozing of blood from independent causes. German. 

 writers draw attention to its frequency in eastern horses at- 

 tributing it to the great development of the vascular system 

 especially of the skin, but its comparative infrequency in the 

 English racer and American trotter would throw doubt on this 

 doctrine. It may be questioned whether the frequency of the 

 disease in Oriental horses is not to be ascribed rather to filariasis. 

 This idea is not contradicted by the especial prevalence of the
