may take the shape of a stretched triangle, whose base is lying 
adjacent to the mid-dorsal-line and whose top does not reach the 
mid-ventral-line (fig. 3). 
Narrowing of the sensible dermatoma-area with transversal division into a dorsal 
and a ventral piece of the dermatoma. 
3. Or the sensible area situated between two insensible area’s 
not only does not reach the mid-ventral-line, but forms even no 
longer an uninterrupted area. 
It is divided into two parts by a transversal insensible zone. The 
isolated ventral piece of dermatoma may in this way have become 
either greater or smaller (fig. 4).

Dorsal piece of the dermatoma. 
4, Or the sensible area situated between two insensible zones, 
above and beneath it, is found only next to the mid-dorsal-line in 
the form of a short triangle. Of a ventral piece of dermatoma there 
is no longer any trace to be found. (fig. 5).
