In the cases of tumor of the spinal cord presented here we are including those which have an intraspinal portion, connected by a small neck with an extraspinal enlargement. While most frequently the communication is through an intervertebral foramen, it may occur through the interlaminal spaces. Intraspinal tumors which are both intradural and extradural, connected by a small constricted stalk through the dura, are placed also in this classification. Destructive metastatic growths are not included in this series.

Hour-glass tumors may appear in any location from the atlas to the coccyx. They have received little consideration in the past, and it is the current impression that they are infrequent. Our particular reason for reporting this group is that these tumors appear with such frequency in our patients with compression of the spinal cord from a tumor that the possibility of an hour-glass tumor always must be considered.
