Minor degreesof the affection are not incomjDatible with life, and several in-stances are known in vdiich such kidneys have been found inadult individuals. Although this condition of kidney is very common andspecimens illustrating it exist in many pathological museums,Ave know very little concerning the early stages. I have ex-amined a well-marked example in a foetus of the sixth month,. Fig. 313.—Congenital cystic kidney ; early stage. {Shattock.) and Shattock observed one at the fourth month. The earlieststage has been observed by Shattock (Fig. 318), and a carefulexamination of the minute structure of the cyst, as well as acomparison of the histology of the cyst with that of the meso-nephros (Wolffian body), induced him to think it probablethat these kidneys consisted of a combination of mesonephrosand metanephros. Virchow regarded the cj^sts as dilatationsof the uriniefrous tubules in consequence of the absence of arenal pelvis. It is, however, a curious fact that congenitalcystic kidney occasionally occurs in association with im- CONGENITAL CYSTIC KIDNEY 589 perforate urethra.
