OF HEMORRHAGES. 



J. The veins are abforbent veffels. 1. Hemorrhages from inflam- 

 mation. Cafe of hemorrhage from the kidney cured by cold bathing. 

 Cafe of hemorrhage from the nofe cured by cold immerfion. II. 

 Hemorrhage from venous parahfs. Of piles. Black foots. 

 Petechia. Confumptim* Scurvy of the lungs. Black nefs oj the 

 face and eyes in epileptic f is. Cure of hemorrhages from venous 

 inability. 



I. As the imbibing mouths cf the abforbent fyftem already 

 clcfcribed open on the furface, and into the larger cavities of the 

 body, fo there is another fyftem of abforbent veiTeis, which are 

 not commonly elteemed fuch, I mean the veins, which take up 

 t£ie blood from the various glands and capillaries, after their prop- 

 er fluids or fecretions have been Separated from it. 



The veins refemble the other abforbent veflels ; as the progres- 

 sion of their contents is carried on in the fame manner in both, 

 they alike abforb their appropriated fluids, and have valves to 

 prevent its regurgitation by the accidents of mechanical vio- 

 lence. This appears fir ft, becaufe there is no pulfation in the 

 \ery beginnings of the veins, as is (cen by nvicrofcopes 5 which 

 mult happen, if the blood was carried into them by the actions 

 of the arteries. For though the concurrence of various venous 

 ftreams of blood from different diftances mutt prevent any pul- 

 fation in the larger branches, yet in the very beginnings of all 

 thei'e branches a pulfation mult unavoidably exift, if the circula- 

 tion in them was owing to the intermitted force of the arteries* 

 Secondly, the venous abforption of blood from the penis, and 

 from the teats of female animals after their erection, is (till more 

 (milarto the lymphatic abforption, as it is previoufly poured in- 

 to cells, where all arterial impulfe mud ceafe. 



There is an experiment, which feems to evince this venou^s 

 abforption, which confifts in the external application of a ftim 

 lus to the lips, as of vinegar, by which they become inftantly 

 pale ; that is, the bibulous mouths of the veins by this tumulus 

 are excited to abforb the blood fatter, than it can be fupplicd by 

 the ufual arterial exertion. See Sect. XXIII. 5. 



1. There are two kinds of haemorrhages frequent in 'difeafes, 

 one is where the glandular or capillary action is too powerfully ex- 

 erted, and propels the blood forwards more baddy, than the veins 

 £an abforb it •, and tlie other is, where the abforbent power of
