H^MORRHAGIES. 229 



DCCCIX. This haemorrhagy may occur at any time of life; 

 but most commonly happens to young persons, owing to the 

 state of the balance of the system peculiar to that age, as men- 

 tioned in DCCLVI. 



DCCCX. Although generally it happens to persons before 

 they have arrived at their full growth, and more rarely after- 

 wards, yet sometimes it happens to persons after their acme', 

 and during the state of manhood : and it must then be imputed 

 to an unusually plethoric state of the system ; to an habitual 

 determination of the blood to the vessels of the nose ; or to the 

 particular weakness of these. 



DC C CXI. In all these cases, the disease may be considered 

 as an haemorrhagy purely arterial, and depending upon an arte- 

 rial plethora ; but it sometimes occurs in the decline of life, 

 when probably it depends upon, and may be considered as a 

 mark of a venous plethora of the vessels of the head. See 

 DCCLXXII. 



DCCCXII. This haemorrhagy happens also at any period of 

 life, in certain febrile diseases, which are altogether or partly of 

 an inflammatory nature, and which show a particular determina- 

 tion of the blood to the vessels of the head. These diseases 

 often admit of a solution by this haemorrhagy, when it may be 

 properly termed critical. 



DCCCXIII. The disease sometimes comes on without any 

 previous symptoms ; particularly, when some external violence 

 has a share in producing it. But, when it proceeds entirely 

 from an internal cause, it is commonly preceded by headachs, 

 redness of the eyes, a florid colour of the face, an unusual pul- 

 sation in the temples, a sense of fulness about the nose, and an 

 itching of the nostrils. A bound belly, pale urine, coldness of 

 the feet, and cold shivering over the whole body, are also some- 

 times among the symptoms that precede the disease. 



DCCCXIV. From the weakness of the vessels of the nose, 

 the blood often flows from them without any considerable effort 

 of the whole system, and therefore without any observable fe- 

 brile disorder ; which, however, in many cases, is, in all its cir- 

 cumstances, very discernible. 



DCCCXV. An haemorrhagy of the nose happening to young 

 persons, is, and may generally be considered as a slight disease
