The caudal boundary of this strychnine-segmental zone passes on 
the medial surface of the nether-leg between the proximal and the 
medial third of the crista tibiae. 
On this portion of the extremity this skin-area lies entirely 
on the medial side, so that it presents itself here as a narrow tongue, 
which for different cases differs in its extending more or less far 
distalward. Sometimes it reaches not farther than the malleolus 
medialis, in other cases it even joins the sole of the medial toe. 
The malleolus medialis either lies in the middle of this narrow 
tongue or just on its cranial boundary. 
Analogous proportions were found by WINKLER and vAN RIJNBERK 
for their dermatomata of £. V.

L. VL. Farther still than the strychnine-segmental-zone of L. V 
that of the V1‘ lumbar spinal segment is lying on the medial surface 
of the extremity. Only a very small portion of it is still situated on 
the lateral surface of the extremity. Whilst the zone of L. V covers 
at the utmost the skin of the medial toe, the strychnine-zone of L. VI 
covers the whole of the medial half of the foot, as well on the 
palmar as on the dorsal surface. Like WINKLER and vAN RIJNBERK, 
whose data for the dermatoma of ZL. VI are in accordance with 
those found by me for the corresponding strychnine-segmental zone, 
stated for the dermatoma, we may therefore say that the strychnine- 
zone of L. VI appears wound spirally around the netherleg and the 
foot. In none of my cases I found this zone connected with the 
midventral or the mid-dorsal line, as little as the authors quoted 
above, found such a connection for their dermatoma of L. VI.
