    Bilharziosis of the bladder.—The general swell- ing and infiltration of the mucous membrane, described in some detail in the preceding section, is probably the earliest manifestation we know and recognise, and this condition is seen at its best in the bladder. Photographs and drawings fail to give an adequate idea of this very characteristic appearance with its wet sea-sand scattered about in the substance of the swollen membrane, and, it may be, thickly infiltrating the whole of the prostate. (Fig. 7.) In the fresh state such a surface is thinly coated with a peculiarly tenacious mucus, in which ova may be found, and which appears to be a great protection to the membrane. Were the surface bereft of this slippery mucus and dry, it would be very friable and easily abraded by the least friction. As it is, it is not until the sandy change becomes marked that the surface of the mucous membrane becomes dry, harsh, and thickened. This may occur to such an extent that the internal lining of the bladder comes to resemble a cyst wall which has undergone an almost general calcification. The surface has then the appear- ance of being coated with much dry sun-baked sand, as opposed to the earlier appearance of wet sea-sand, which is definitely deep within the substance of the mucous membrane. (Fig. 8.) Another change is a patchy hyperemia associated with minute extravasations, either as an independent manifestation, or in an already thickened and in- filtrated mucous membrane. This may be confined to
