The measurings on Jan. 22th are the following: 
Largest breadth 
Mid-dorsal line. of central area. Mid-ventral line. 
Analgetic area (3 roots) 4.6 cm. 2.4 cm. Ae, 
The distance from the mid-dorsal to the mid-ventral line is: to the right in 
the cranial area 21.5 c.m., in the caudal area 21 c.m. and to the left in the 
analgetic area 22 cm. 
The most important narrowing in the cranial analgetic area to the right is at 
11 em. distance from the mid-dorsal, at 10.5 c.m. distance from the mid-ventral line, 
The most important narrowing in the caudal analgetic area to the right is at 
9 cm. distance from the mid-dorsal, at 13 e.m. distance from the mid-ventral line. 
The most important narrowing in the analgetic area to the left is at 9 c.m. 
distance from the mid-dorsal, at 13 em. distance from the mid-ventral line. 
Oxzservation VI. A black male dog. (Series IÌ, dog VI) On Jan. 1st 1902 under 
rigorously aseptic conditions, ave cut through extradurally: to the right the 11th, 
12th, 13th, 15th, 16th and 17th pair of roots; to the left the 12th, 13th, 15th 
and 16th. 
On both sides the 14th remains intact, as is confirmed by the autopsy on 
Jan. 19th. The sensibility, determined and noted on Jan. 18th, presents the 
images, rendered by fig. 24.
