    in the upper cervical region appears to represent there the vesicular column of Clarke, even with this group as a guide to the probable position of Clarke’s column, I have never been able to satisfy myself that in the redistribution and dislocation of grey matter, that can be followed out in a series of sections passing upward into the bulb, the vagus nucleus is continuous with the upper part of Clarke’s column, or that its position is that which the upper extremity of Clarke’s column would assume. Neither does the histological appearance of the vagus nucleus altogether favour, in my opinion, the view that it represents Clarke’s column. Its cells appear to resemble more closely, in form and arrangement, the smaller fusiform cells of the lateral horn of the cord—such as, for instance, are seen in fig. 4, Plate 3. On the other hand, the cells of the cuneate nucleus do much resemble, in form and arrangement, the cells of the vesicular column of the cord. Explanation of Plates 3, 4. Figure 1, Plate 3. Portion of the anterior column adjacent to the mesial edge of the anterior gvey cornu. Tri-radiate nerve-cell lying between the fasciculi of white matter. From a section, stained with carmine, and prepared from the cord of the Dog, between the 1st and 2nd cervical nerve-roots. Camera lucida and apochromatic immeision (Zeiss), with ocular 4. Figure 2, Plate 4. Portion of tlie anterior column adjacent to the mesial edge of the grey cornu. Tri-radiate nerve-cell lying between fasciculi of white matter. A larger nerve-cell belonging to the inner gioup of the grey cornu is seen. Weigert hrematoxylin preparation, from the cord of a full-term human foetus, at the level of the .5th lund)ar nerve-root. Camera lucida and Zeiss apochro- matic immersion, with ocular 4. Figure 3, Plate 3. Out-lying cells in the l.'iteral column, near the cell-group of the lateral horn. At level of 8th thoracic nerve-root of Macacus ; stained with aniline blue-black. Camera lucida and Zeiss apochromatic immersion, with ocular 4. Figure 4, Plate 3. Out-l}dng cells in tlie lateral column in the neighbourhood of the lateral grey cornu. Picro-carmine ])repa]’ation, from human cord af the level of the 7th cervical neive-i'oot. Camera lucida, and Zeiss olijective BB, ocular 2. Figure 5, Plate 4. Out-lying cells in the lateral cohmin, outside the fonnatia reticu- laris. Weioert hfcmato.xylin preparation, from cord of young Macacus. Zeiss objective a, ocular 4. Figure f), Plate 4. Out-lying cell in the ])osterior column. Two cells of Clarkes column in tlie grey ma,tter. Weigert haeimitoxylin preparation from liuinan cord at level of 12th thomcic nerve-root.
