It is of interest to note the anatomic misdirection of fiber that sometimes occurs in other neural regenerations, particularly in the facial nerve. The facial muscles will not always react as they should when a facial nerve regenerates. The amazing thing is that the third nerve will regenerate to the point where, for all practical pur¬ poses, it functions normally. To see one of these nerves at the time of surgical intervention, one would say that the nerve could never regenerate because only the tiniest thread held the two ends together. Many times the portion of the nerve trunk that is left is only about one tenth of the normal diameter of the third nerve. Dr. Smith inquired about the careful obser¬ vation and recording of everything that happens in regard to the movement of the eyeballs and particularly of the pupils. My material has been voluminous, and my associates and I are now gaining enough experience on which to plan our obser¬ vations. A great deal of this material was seen by various ophthalmologists and many neurologists, and we have not really worked out an accurate routine of examination. I do not believe that sympathetic factors have anything to do with causing mul¬ tiple aneurysms. It is fairly well established that most of these are due to a congenital malformation, and I cannot conceive of sympathetic inhibition having anything to do with their formation. The ophthalmologist is most frequently the first to examine patients with intra;ranial aneurysms ; therefore he must be informed as to the appropriate forms of treatment.Clinical experience has shown that esophageal hiatus hernia in older persons often presents diagnostic and therapeutic problems. The reasons for this are that the hiatus hernia may exist without symptoms ; it may produce a syndrome which simulates other diseases, as for example, cholelithiasis or cardiovascular disease ; it may be associated with other diseases and produce complications, the symptoms of which dominate the clinical picture, and, finally, the treatment of hiatus hernia, whether medical or surgical, is not infrequently followed by a recurrence of the symptoms. In this article we wish to stress two aspects of this subject, namely, varied clinical manifestations of associated diseases of hiatus hernia which were encountered in a group of patients and the surgical treatment by phrenic interruption. r CLINICAL STUDY This study is based on a series of 29 patients whose age range was from 50 to 86 years. Seven were men ; 22 were women. In each case the presence of an
