THROMBUS, from ^^ojxQo:, coagulated blood, a clot of 

 blood. The term has alfo been applied to a tumour, formed 

 of a colleAion of cxtravafated blood under the integuments 

 after bleeding. When fuch an extravafation, though of 

 fome extent, is not confiderable, it is ufually called an 

 ecchymofis ; which fee. 



A tiirombus fometimes depends on the furgeon having 

 totally divided the vein ; but much more frequently on his not 

 having made the opening in the vefTel properly correfpond to 

 tliat in the fl-:i[i. The patient's altering the pofture of his 

 arm, while the blood is flowing into the bafin, will often caufe 

 an interruption to the efcape of the fluid from the external 

 orifice of the punfture ; and, confequcntly, it infmuates itfelf 

 into the cellular fubfl:ance in tlie vicinity of the opening in 

 the vein. In proportion as the blood iflues from the veflel, 

 it becomes efTufcd between the flcin and fafcia in the inter- 

 fbices of the cellular fuhftance, and this, with more or lefs 

 rapidity, and in a greater or leffer quantity, according as 

 the edges of the lliin impede more or lefs the outward 

 efcape of the fluid. Sometimes, alfo, a thrombus forms 

 after venefeftion, when tlie iifual dreffings, comprefs, and 

 bandage, have been put over the punfture, and the patient 

 imprudently makes ufe of the arm on which the operation 

 has been done. This is more particularly liable to happen 

 when a very large opening has been made in the vein. 



The accident is not attended with any danger when the 

 extravafation is inconfiderable ; for, in this circumftance, 

 the tumour generally admits of being eafily refolved by 

 applying to it linen dipped in any difcutient lotion. If the 

 fwelling (hould be more extenfive, applying to it a comprefs 

 ■wet with a folution of common fea-f;!lt, is deemed a very 

 efficacious plan of promoting the abforption of the cxtra- 

 vafated blood. Brandy, and a folution of the muriate of 

 ammonia in vinegar, are likewife eligible applications. 



It fometimes happens, that a thrombus induces inflam- 

 mation and fuppuration of the edges of the punfture. The 

 treatment is now like that of any little abfcefs : a common 

 linfeed poultice may be applied, and any confiderable accu- 

 mulation of matter fliould be prevented, by making an 

 opening with a lancet in proper time. As foon as the 

 inflammatory iymptoms have ceafed, difcutients fhould be 

 retorted to again, for the purpofe of difperfmg the remain- 

 ing clots of blood and furrounding induration. Cooper's

 called in Englifb the mijfel-bird, and ufually known 

 among us by the fimple name of thrujh. It is called -vifci- 

 vorus by authors, from its refemblance in colour to the 

 other ■vifci'vorus, not from its feeding on the mifletoe-berrics, 

 as that does. 



It refembles the mifTel-thrurti in colour, except thSt the 

 inner coverts of the wings are yellow. 



It feeds on worms, fnails, and fmall infefts, and remains

 and lines the neft; ^ith mud. On this it lays five or fix 

 eggSj which are of a blueifh-grcen, variegated with a few 

 black fpots. It fits on hedges and buflies, and fings very 

 agreeably. 



The throftle is the fined of our finging-birds, not only

 continuance of its harmony ; as it obliges us with its fong 

 for nearly three parts of the year. See Turdus.
