of blood from the mouth, as vomiting and coughing often 

 mutually excite each other ; so they may be frequently joined, 

 and render it doubtful whether the blood thrown out proceeds 

 from the lungs or from the stomach. We may, however, gen- 

 erally decide, by considering, that blood does not so frequently 

 proceed from the stomach as from the lungs ; that blood pro- 

 ceeding from the stomach commonly appears in greater quantity 

 than when it proceeds from the lungs ; that the blood proceed- 

 ing from the lungs is usually of a florid colour, and mixed with 

 a little frothy mucus only ; whereas the blood from the stomach 

 is commonly of a darker colour, more grumous, and mixed with 

 the other contents of the stomach ; that the coughing or vomit- 

 ing, according as the one or the other first arises, in the cases 

 in which they are afterwards joined, may sometimes point out 

 the source of the blood ; and, lastly, that much may be learned 

 from the circumstances and symptoms which have preceded the 

 hsemorrhagy. 



Those which precede the haemoptysis enumerated in 

 DCCCXXXVII. are most of them evident marks of an 

 affection of the lungs. And, on the other hand, the haemate- 

 mesis, or issuing of blood from the stomach, has also its peculiar 

 symptoms and circumstances preceding it ; as, for instance, 

 some morbid affection of this organ, or at least some pain, 

 anxiety, and sense of weight, referred distinctly to the region of 

 the stomach. To all this may be added, that the vomiting of 

 blood happens more frequently to females than to males ; and 

 to the former, in consequence of a suppression of their men- 

 strual flux : and by attending to all these considerations 

 (DCCCXLIL -DCCCXLV.), the presence of the haemop- 

 tysis may commonly be sufficiently ascertained.

DCCCXLVI. This disease is sometimes attended with little 

 danger ; as, when it happens to females in consequence of a 

 suppression of the menses ; when, without any marks of a pre- 

 disposition, it arises from external violence ; or when, from 

 whatever cause arising, it leaves behind it no cough, dyspnoea, 

 or other affection of the lungs. Even in such cases, however
