Variations in the gross anatomy of the spinal cord are unusual. Observation of many spinal cords, in our regular class dissections during a period of five years, tends to confirm this statement. During this period one double spinal cord was found. A careful search of the literature failed to disclose the report of a case similar to the one I describe. Although it was impossible to obtain a clinical history, the variation is so unusual as to be of more than casual interest to the clinician, the surgeon and the anatomist.
This rare variation was encountered during the regular laboratory work in the dissecting rooms at the Daniel Baugh Institute of Anatomy of the Jefferson Medical College. Unfortunately the spinal cord was not in a state of preservation to admit microscopic study of serial sections.
The specimen was obtained from an adult white male cadaver, well nourished, about 35 years
