The serous membrane inold hydroceles may be more or less thick-ened, and even the seat of calcareous de-posit. Adhesions formed between the twolayers of the tunica vaginalis may, accord-ing ?^o their length and extent, alter theusual position of the testicle, so that it ap-pears in front, instead of lying in its usualplace at the posterior and lower part of thedistended sac; or they may subdivide thecavity, and produce thus a multilocularhydrocele. The natural cul-de-sac whichexists between the epididymis and the body of the testicle, is some-. Drawing of larg-e hydro-cele, combined with scrotalhernia.

The morbid action in hydrocele is confinedto the serons membrane; the testis either remains natuial, or issomewhat flattened, and, in some cases, partially atrophied by thepressure of the fluid. When, however, the original seat of diseaseis in the gland itself, the serous covering is often secondarilyinvolved, so that serous efiusion in the sac is very often associatedwith chronic orchitis, or other diseases of the testicle ; and such acombination has been termed a hydro-sarcocele. Hydrocele seemsto be met with on either side in about an equal proportion ofcases. In congenital hydrocele the dropsical tunica vaginalis retains itsfoetal communication with the peritoneal cavity.
