Rarely it extends backward in the middle arterial fieldand invades the neck of the posterior horn, and usually it embraces theadjoining white matter of the cord to a varying extent. It is evidentthat the lesion is not strictly systematized, and it is equally evident thatit is of vascular distribution. Batten^ asserts, upon rather convincingevidence, that the vascular fault is primarily thrombotic, and thatthe lumbar cord is especially aftected, owing to the circulatory disad-vantages of the part. Wickmah does not accept the thromboticexplanation, and probably, if such takes place, it is of
