[See Plate III. fig. 1.] While those which have been inflamed, cease to be trans- parent, and do not exhibit the same degree of vascularity. The appearance of the testicle would seem to indicate that these cysts are enlargements, and obstructions of the seminiferous tubes, having become increased by the accumulation of fluid within them, and connected with each other at their different convolu- tions ; but their formation must be in a great degree conjectural as to whether they be produced in the cellular tissue, by effusion into its cells, or in the seminiferous tubes. It is quite certain, however, that they are not of the nature of animal hydatid; I am inclined to the opinion, that they are formed of enlarged and obstructed seminiferous tubes; for when I minutely dissect them, although at first sight they appear to be cysts, yet when traced, they are not distinct bags, but send out solid processes, by which they are connected with other cavities, as the Plate will show. The affection ought, therefore, to be called the Tubular Disease of the Testis. I have seen absorbent glands undergo very similar changes, from enlargement and obstruction of their cells and vessels, and having a fluid secreted into them.
