Physiology. — “Structure and function of the trunk-dermatoma.” III. 
By Prof. C. WINKLER and Dr. G. VAN RIJNBERK. 
(Communicated in the meeting of February 22, 1902). 
Before treating of that part of the dermatoma, situated between 
the mid-dorsal and mid-ventral lines, which may be called the 
“lateral part’? of the dermatoma, we will proceed with the com- 
munication of a few chosen experiments from the extensive series 
at our disposition. 
OBSERVATION 1. Young black female dog. (Series I Nr. XVII). On Aug. 9th 
1901, under rigorously aseptic conditions, the 19th pair of roots is sectioned 
extradural on both sides. On the next day the sensibility to pain is determined 
by pinching with a fine artery-pincet.
