(h) Annular Stricture.— This form isbroader, as if a flat tape had been tiedaround the canal (Fig. 26). The term isapplied to strictures not over a quarter ofan inch long. (c) Tortuous or Irregular Stricture.—Here all other varieties come in. Such a stricture may be an inch ormore long—even the whole pendulous urethra may be in a hardened,stiffened, narrowedcondition. The amount ofcontraction in strict-ure varies from analmost imperceptiblenarrowing of thecanal to nearly abso-lute occlusion, sothat, after death, itmay be impossibleto introduce even abristle through it.Absolute occlusiondoes not occur ex-cept after the canalhas been severed byan injury, and theurine has found anescape through thewound ; or wherenumerous large fist-ulas have long ex-

Number of Strictures.—Stricture is usually single. Out of twohundred and seventy preparations, showing stricture, found in the mu-seums of Loudon, Edinburgh, and Paris, Thompson * found, in twohundred and twenty-six cases, solitary stricture. Hunter found, in asingle urethra, six ; Lallemand, seven ; Colot, eight; Leroy dEtiolles,eleven, and Otis fourteen. Thompson has seen three—at most four—and believes that if more are found they must be considered as irregu-lar contractions of the same stricture. Seat of Stricture.—Upon this subject the laborious investiga-tions of Thompson, upon the two hundred and seventy specimensabove referred to, must be considered
