232 PRACTICE OF PHYSIC. 



tendency to a profuse haemorrhagy appears, a bleeding at the 

 arm may be proper, even in young persons ; but, in the case 

 of adults, it will be still more allowable, and even necessary. 



DCCCXXV. In persons of any age liable to frequent re- 

 turns of this haemorrhagy, when the measures proposed in 

 DCCCXVH. et seq. shall have been neglected, or, from pecu- 

 liar circumstances in the balance of the system, shall have 

 proved ineffectual, and the symptoms threatening haemorrhagy 

 (DCCXXXVIII.) shall appear, it will then be proper, by 

 blood-letting, cooling purgatives, and every part of the anti- 

 phlogistic regimen, to prevent the haemorrhagy, or at least to 

 prevent its being profuse when it does happen. 



DCCCXXVI. In the circumstances just now mentioned 

 (DCCCXXV.), the measures proposed are proper, and even 

 necessary ; but it should at the same time be observed, that 

 these are practised with much less advantage than those pointed 

 out in DCCCXXI V. because, though those suggested here may 

 prevent the coming on of the haemorrhagy for the present, they 

 certainly, however, dispose to the return of that plethoric state 

 which required then: being used ; and there can be no proper 

 security against returns of the disease, but by pursuing the 

 means proposed in DCCCXXIII. 



DCCCXXVII. When the hsemorrhagy of the nose happens 

 to persons approaching to their full growth, and when its returns 

 have been preceded by the symptoms DCCCXIIL, it may be 

 supposed, that, if the returns can be prevented by the measures 

 proposed in DCCCXXV., these may be safely employed ; as 

 the plethoric state induced will be rendered safe, by the change 

 which is soon to take place in the balance of the system. This, 

 however, cannot be admitted; as the evacuations practised upon 

 this plan will have all the consequences which, I have already ob- 

 served, may follow the recurrence of the haemorrhagy itself. 



DCCCXXVIII. When the hsemorrhagy of the nose shall 

 be found to make its returns at nearly stated periods, the mea- 

 sures for preventing it (DCCCXXV.) may be practised with 

 greater certainty ; and, upon every repetition of blood-letting, 

 by diminishing the quantity taken away, its tendency to induce 

 a plethora may be in some measure avoided. When, indeed, 

 the repetition of evacuations is truly unavoidable, the dimmish-
