The pressure due to the accumulated urine causes the renal tissue, first the medullary substance and afterwards the peripheral zone, to undergo atrophy. The kidney is represented by a vast C3\stic cavity, and the lobules by culs-de-sac; the cortical layer may become atrophied to such a degree as to form merely a fibrous sheath, the primary constituent elements of which are difficult to discover. From 20 to 40 pints of liquid may sometimes be found in the cystic kidney. Diagnosis. The condition is rarely diagnosed, because, as one of the kidneys contiinies to act, no acute disturbance follows. Only in cases where the cystic kidney projects into the flank are suspicions aroused. Examination per rectum will then permit of the diagnosis being made. Prognosis. Hydro-nephrosis being, as a rule, unilateral, the
