The deformity maypossibly have been of congenital origin, or it may havebeen produced readily enough by mechanical means; so itis difficult to know whether to class Chiaris case amongthe true cases or among the erroneous cases of malforma-tions of the cord. (The case would seem to me to lookmore like a bruise than a malformation.) Xo. 19. Oyurmans Case (39), 1892.—Gyurman, in ex-amination of a case of syringomyelia, describes an addi-tional anterior horn surrounded by extra white matter, fusedwith the cord on its right lateral aspect. Gyurman de-scribes this as heterotopia, and believes it to be of con-genital origin. I doubt the congenita] origin of this sup- ^=^. posed heterotopic condition, and have selected one ofGyurmans drawings (see Fig. 23) as indicating a bniise ofthe cord. Xo. 20. Feisfs Second Case (40), 1892.—In this caseare described with the same thoroughness as in the firstinstance malformations of the gray matter, and aberrantbundles of white matter, in the spinal cord of a man agedthirty-eight, who liad had fatal general paresis for two yearsand a half. The case was not complicated by cord disease,except that there was a degeneration of the columns ofGoll and a trifling marginal sclerosis. The appended draw-ings (see Fig. 24), selected from the authors plates, showvery faithfully the artitirial character of the supposed het-erotopic condition. Xo. 21. Koppens Cases (41), 1892.—Koppen cites twocases of acute formation of cavities in the spinal cord —one wliieh showed heterotopia of the gray matter. Theseare reviewed here not to class them positively as erroneouscases, but to suggest that
