*f they are drawn immaturely, their roots are found 

 complete. Similar to this Mr. Hunter has obferv- 

 ed, that where a dead piece of bone is to exfoliate, 

 or to feparate from a living one, the dead part 

 does not putrefy, but remains perfe&iy found, while 

 the furface of the living part of the bone, which is 

 in contact with the dead part, becomes abforbed, 

 and thus effects its feparaiion. Med. Comment. 

 Edinb. V. 1.425. In the fame manner the calca- 

 reous matter of gouty concretions, the coagulable 

 lymph depofited on inflamed membranes in rheu- 

 matifm and extravafated blood become abforbed; 

 which are all as folid and as indiflbluble materials as 

 the new veflels produced in inflammation. 



This abforption of the new veflels and depofited 

 fluids of inflamed parts is called resolution : it Is 

 produced by firfl ufing fuch internal means as de- 

 creafe the pain of the part, and in confequence its 

 new motions, as repeated bleeding, cathartics, dilu- 

 ent potations, and warm bath. 



After the veflels are thus emptied, and the ab- 

 forption of the new veflels and depofited fluids is 

 evidently begun, it is much promoted by (Umulating 

 the part externally by folutions of lead, or other 

 metals, and internally by the bark, and fmali doles 

 of opium. Hence when an ophthalmy begins to 

 become paler, any acrid eye-water, as a foiution of 

 fix grains of white vitriol in an ounce of water, 

 haflens the abforption, and clears the eye in a very 

 fhort time. But the fame application ufed a few 

 days fooner would have increafed the inflammation. 

 Hence after evacuation opium in frnall cjoks may 

 contribute to promote the abforption of fluids de- 

 pofited on the brain, as obferved by Mr. Bromfield 

 in his treatife of furgery. 



2. Where an abfcefs is formed by the rupture of 

 thefe new veflels, the violence of inflammation 

 ceafes, and a new gland feparates a material called 



pus;
