The measurings on Jan. 18th are the following : 
Mid-dorsal line. Largest breadth Mid-ventral line, 
of central area. 
Cranial analgetic area (3 roots) 2.7 c.m. 2.4 c.m. 7.6 c.m. 
Sensible area (1 root) aa 6 ; is not reached 
(distance0.4 c.m.) 
breadth of sen- 
sible area at that 
point 1.9 em.

LE RT SDE, 
Measurings on Jan. 18th are the following: 
Mid-dorsal line. Largest breadth Mid-ventral line. 
of central area. 
Cranial analgetic area (2 roots) 1.8 c.m. Interrupted (O or —) 6.4 c.m. 
Sensible area (1 root) Bs + 65cm. is not reached 
(distance0.3 cam.) 
breadth of sen- 
sible area at that 
point 1.1 cm. 
Caudal analgetic area (2 roots) 3.4 ¢.m. Interrupted (0 or —) 6.4 c.m. 
The distance from the mid-dorsal to the mid-ventral line is in the cranial anal- 
getie area to the right 24.5 c.m., to the left 26 c.m.; and in the caudal analgetic 
area to the right 23.5 c.m.. to the left 24.5 c.m. 
The narrowing of the right caudal area begins at 9 c.m. distance from the 
mid-dorsal line. 
The top of the dorsal triangle of the left cranial area is situated at 11 cm. 
distance from the mid-dorsal line, the top of the ventral triangle at 13 ¢.m. dis- 
tance from the mid-ventral line. The breadth of the interrupting band is 1.5 cam. 
For the left caudal area these distances become relatively 10 c.m. and 11 cm, 
whilst here the interrupting band has a breadth of 3 em. 
OBsERvATION V. A large brown dog. (Series Il Nr. VII). On Jan. 26th 1902 
are cut through extradural under aseptic conditions: to the right the 12th, 13th, 
14th, 16th, 17th and 18th pair of roots, to the left the 13th, 14th, 16th and 
17th pair of roots. The autopsy on Febr. 4th confirms the intactness of the 15th 
pair of roots on both sides. 
The determination. of sensibility on Jan. 27th proves the extension of the 15th 
dermatoma to be such as is represented by fig. 25.
