![mal matter, and not of a malignant character. The disease is not of common occurrence. A young man twenty years of age, without any obvious cause for it, found a tumour at one extremity of the testis. It was at first unattended with pain ; was usually soft to the feel. It grew larger, and was at one time soft, at another hard; generally attended with little pain, some- times extremely painful. It was extracted after a twelve- month. On cutting into the testicle, it was found to be composed of numerous cysts, of different sizes and forms, containing a serous fluid in some parts: at others it was like the white of egg. In one part the testis was very compact, and at that part there was a tendency to suppuration.—Cooper. II. The tunica vaginalis participates in the acute inflam- mation of the testis 5 is liable to chronic inflammation, thick- ening, adhesion, hydrocele, hematocele, malignant disease. 1. Hydrocele is a sac containing water connected with the testicle or the cord. It presents two varieties—hydrocele of the tunica vaginalis, and encysted hydrocele. a. Hydrocele of the tunica vaginalis is so called from the liquid effused being contained in that cavity. The fluid is of an amber colour, and quite transparent. A large portion of it coagulates with heat, and on the addition of nitric acid. It resembles very nearly the serum of the blood, both in its appearance and chemical composition; the chief dif- ference being, that it contains rather less albumen. Every now and then a number of small greasy particles of a yellow colour, with something of a metallic lustre, are found in it, which are probably adipocire. [x. 180.] The tunica vaginalis often remains unaltered in hydro- cele. Sometimes however, especially in old hydroceles, it becomes thickened. Occasionally, conjointly with thicken- ing, the inner surface is found honeycombed, the result of effusion of lymph upon it. Occasionally, little bodies, like the loose cartilages of a joint, grow from its free surface, [.r. 162.] The sac which contains the water often exhibits an hour- glass contraction at its middle : at this part the wails of the](https://iiif.wellcomecollection.org/image/b21066735_0595.jp2/full/800%2C/0/default.jpg)
