with the gaftric branch of the vena portarum. It 

 is pofiible, that when the motion of the lymphatic 

 becomes retrograde in fome difeafes, that blood 

 may obtain a pafTage into it, where it analtomofes 

 with the vein, and thus be poured into the in- 

 teftines. A difcharge of blood with the urine fome- 

 times attends diabetes, and may have its fource in 

 the fame manner. 



Mr. A , who had been a hard drinker, 



and had the gutta rofacea on his face and bread:, 

 after a ftroke of the palfy voided near a quart of a 

 black vifcid material by (tool : on diluting it with 

 water it did not become yellow, as it muft have 

 done if it had been infpiffated bile, but continued 

 black like the grounds of coffee.

 veins of the inteftines : all which occur more fre- 

 quently in thofe who have difeafed livers, than in 

 any others. Hence troublefome bleedings of the 

 nofe, or from the lungs with a weak pulfe ; henee 

 haemorrhages from the kidneys, too great menftru- 

 ation ; and hence the oozing of blood from every 

 part of the body, and the petechias in thofe fevers, 

 which are termed putrid, and which is erroneouily 

 afcribed to the thinnefs of the blood : for the blood 

 In inflammatory difeafes is equally tiuid before it 

 coagulates in the cold air. 



Is not that hereditary confumption, which occurs 

 chiefly in dark-eyed people about the age of twenty, 

 and commences with flight pulmonary haemorrhages 

 without fever, a difeafe of this kind ? Thefe hse- 

 morrhages frequently begin during fleep, when the 

 irritability of the lungs is not fufficient in thefe 

 patients to carry on the circulation without the 

 ailillance of volition ; for in our waking hours, the 

 motions ot the lungs are in part voluntary, efpeci-
