L. 1. What strikes us first of all, is the fact that this stryehnine- 
segmental zone obviously lies more caudalward on the body than the 
preceding one. To ascertain this, we have only to compare the caudal 
boundaries of these two zones in their relation to the crista iliaca, 
as shown resp. in Fig. V and in Fig. VII. Practically this zone is 
not vet lying on the skin of the extremity, though we may perceive 
the neighbourhood of this latter by the small linguiform projection 
presented by this zone in the skinfold of the groin. See Fig. VII. 
WINKLER and van RIJNBERK found analogous proportions for their 
dermatoma of JZ. I.

L. ll is the first segment, the strychnine-zone of which lies on 
the skin of the extremity. Compared with the zone of Ll it is 
situated more candalward, which is shown among others by the fact 
that the crista ilei now lies partly within this skin-field. 
This strychnine-segmental zone extends very far on the lateral 
surface of the extremity, whilst it covers likewise a great part of 
its medial surface. 
The most distal point of this zone on the extremity is situated at 
about 2'/, em. from the upper margin of the patella, as is shown 
in Fig. IX and X. In all my cases the situation of this distal boundary 
was the same, I also always found the fixed points of the knee- 
joint lying outside the zone. 
The statements of Winkuer and van RUIJNBERK concerning the 
dermatoma of Zi, are perfectly identical with what I found about 
this zone. At the mid-ventral line the strychnine-segmental-zone is
