![that case a truss should be worn to prevent hernia. In time the liquid is absorbed, and the canal closes. Hydrocele is often combined with chronic inflammation of the testes, and the patient suffers considerable pain from the pressure of the liquid on the inflamed gland. The pain is relieved by letting off the water. b. An encysted hydrocele is a thin membranous cyst, or- dinarily containing a transparent water, which contains no coagulable matter : held in a spoon over the flame of a can- dle, it nearly all evaporates, leaving the smallest possible re- siduum of animal matter. Occasionally, however, the con- tents are a yellow serum, like the fluid of common hydrocele. Encysted hydrocele occurs in the cord, upon the epididymis, when it lies between that tube and the tunica vaginalis; upon the body of the testis, when it is contained between the tu- nica vaginalis and the tunica albuginea. \x. 175.] This kind is commonly of slow growth, and forms a tumour of small size, which remains without changing for years. When punctured, it is more likely not to reaccuraulate than common hydrocele. 2. Hematocele. This term is given to two affections—one, effusion of blood, the other, of sanguinolent serum into the tunica vaginalis. [:r. 178.] The latter, I believe, may alternate with hydrocele, the secretion being from an accidental cause dark and turbid at one time, clear and serous at another. It may likewise arise from blood being mixed with the serum of the hy- drocele, in consequence of a bruise on the testes, or from a vessel having been punctured in tapping a pre-existing hy- drocele. The former is the direct consequence of mechanical injury to the part; if the effusion of blood is small, it will be par- tially or wholly absorbed. If of any quantity, it should be evacuated, lest its pressure should excite disease or absorp- tion of the testis. The proper method is to make an incision into the sac, allow what is disposed to do so to come away, and then to apply a poultice, into which the effused blood will gradually be discharged. 3.
