The following report embodies the results of a pathologic study of.seven cases of paralysis associated with chronic kidney disease, such as are not infrequently regarded as of uremic origin, in which no gross anatomic change was found to account for the paralysis. These cases were studied with a view of determining, if possible, the cause, or causes, of paralysis, as we observe it, in persons brought to the hospital who lived under observation but a short time, and who present paralysis which can hot be attributed to cerebral hemorrhage, with which the evidences of grave nephritis are often associated.
