These are, in all probability, dilated and closed follicles; and in this respect they bear a strong analogy to the cysts of the kidney, which are found to be dilated uriniferous tubes. In the situation of the uvula vesicse, the fold of mucous membrane is occasionally thrown up, so as to form a remarkable pro- jection or bar at the neck of the bladder. Mr. Guthrie especially directed the attention of surgeons to this, but it has been met with often by others, and there is a good repre- sentation of it in Baillie's Morbid Anatomy. No doubt it has often been confounded with supposed enlargement of the middle lobe of the prostate, with which it is often combined, hut of which, in many cases, it is wholly in- dependent. Tn a surgical point of view it is of very great interest. The bar in question, in its most simple form, consists simply of a double fold of mucous membrane, raised at right angles from the bladder ; in other cases, there is found between the layers of mucous membrane a quantity of a substance of an in- termixture of elastic and organic muscular tissue, similar to what is found in the neck of the bladder in the normal condition ; whilst in other instances, apparently in the more ad- vanced stages of the disease, the middle lobe of the prostate, considerably hypertrophied, is found as if it had forced its way between the mucous layers, and thus carried the fold with it ; in the latter condition, it will be found in the form of two wing-like processes, one on either side, connecting the middle lobe to the side of the bladder. The disease is necessarily attended with difficult micturition, and leads to retention of urine. The diagnosis between retention from this cause and from enlarged third lobe is difficult, but practically it is not unimportant, as Mr. Guthrie thinks it may be cured. In the
