The process thus comes to a standstill, butthe result is considerable diminution of the calibreof the artery, which, however, still permits a thincurrent of blood to pass through it. In the secondcase the cellular deposit in the intima is convertedinto fibrous connective tissue or cicatricial tissue. EXPLANATION OF PLATE XIX. Fig. 1.
