H^EMOHRHAGIES. 217 



haemorrhagies does not always arise from the original constitu- 

 tion of the system, nor even from long habits established by 

 nature ; but upon the contrary there is a variety of exciting 

 causes which may arise accidentally, and give occasion to 

 hoemorrhagy. Certainly the obviating these occasional causes, 

 and the plethoric state in so far as it arises from them, is not 

 only allowable but necessary." 



DCCLXXXI. Upon the whole of this subject, I conclude, 

 that every preternatural haemorrhagy, or in other words, every 

 one except that of the menses in females, is to be avoided, and 

 especially the returns of it prevented ; and I therefore now 

 proceed to mention, how haemorrhagy, and its recurrences, may, 

 and should be prevented. 



DCCLXXXII. From the principles delivered above, it 

 will immediately appear, that the prevention, either of the first 

 attacks, or of the returns of haemorrhagy, will chiefly, and in 

 the first place, depend upon the preventing or removing any 

 considerable degree of a plethoric state which may happen to 

 prevail in the body. It is true, that, where the haemorrhagy 

 depends upon the particular conformation of certain parts, 

 rather than upon the general plethoric state of the whole, the 

 measures for removing or preventing the latter may not always 

 be sufficient for preventing haemorrhagy : but at the same time 

 it must be evident, that determinations, in consequence of the 

 conformation of particular parts, will always be urged more or 

 less, in proportion to the greater or less degree of the plethoric 

 state of the whole system ; and, therefore, that, even in the 

 cases depending upon particular conformation, the preventing 

 or removing an unusally plethoric state, will always be a chief 

 means of preventing haemorrhagy. It is further to be attended 

 to, that there may be several inequalities in the balance of the 

 system, which may have little or no effect unless when the 

 system becomes preternaturally plethoric ; and, therefore, that, 

 in all cases, the preventing or removing of the plethoric state 

 of the system, will be a chief means of preventing the first at- 

 tacks, or the returns of haemorrhagy. It now, therefore, re- 

 mains to explain, how the plethoric state of the system is to be 

 prevented or removed*
