This transparency can be demonstrated, ex-cept in rare instances of old hydroceles with very thick walls, by darkeningthe room and then placing the tumor, its scrotal coverings being made tense,in the line of vision between the eye and a bright light. Oftentimes by sodoing a dark spot can be detected marking the position of the testicle,which lies in the tumor largely surrounded by fluid. The fact that invaginal hydrocele the testicle is within the fluid tumor, and consequently can-not be felt outside of it, is a point of much diagnostic importance. Aspira-tion will demonstrate the fluid contents of the tumor. If one bears in mind HYDROCELE. 223. Fig. 64.—Hydrocele (Keen and White). the characteristic features of vaginal hydrocele, there ought commonly to belittle difficulty in making a differential diagnosis. Occasionally, however,an extensive hydrocele may simulate an inguinal hernia. Hematocele alsoresembles hydrocele in many respects. The points of difference, however,will be studied when this latter condition is considered. If hydrocele isnot of considerable size, its upperrounded margin can be felt below theexternal abdominal ring, and conse-quently inguinal hernia can be imme-diately excluded. Sometimes, how-ever, the upper border extends so farup that it seems to the feel to be con-tinuous with the external ring, and itis such cases that resemble more orless closely inguinal hernia. The fol-lowing are, however, the importantpoints of difference : The history ofhydrocele is that of a dependent tumorwhich has gradually extended upward
