Chronic Inflammation.

to present a villous appearance, with finger-like, reddish and later 

 whitish processes (filaments) ; growing in a lluid exudate this new 

 tissue is found floating and waving back and forth with the move- 

 ments of the viscera. When there is motionless contact with an 

 opposed and similarly inflamed surface, the two surfaces become 

 adherent, at first by the embryonic tissue, but later by capillary 

 anastomoses and the thorough interlacing of the developing tissue. 

 Thus adiicsivc inflammation, the formation of adhesive bands, often 

 in the form of broad connective tissue cords, results. When

the embryonic tissue develops beneath a serous surface it may give 

 rise to broad flat pale areas of thickening, the so-called milk patches. 

 About abscesses it forms abscess walls; along fasciae or extending 

 along other connective tissue structures (submucous, subcutaneous 

 tissue or about fistulous passages) it forms extensive indurated 

 layers. When the process involves the connective tissue structures 

 of an organ diffusely, as between the columns of liver cells or in 

 the kidney, this interstitial inflammation occasions a widespread 

 firm induration of the organ {indurative intlammation). The in- 

 flammatory embryonic tissue gradually becomes pale and firm and
