fibers as well as their percentage values are also given, the 
observed number being taken as the standard. 
The shank is tested in the same way. For the foot 
observations are lacking. A study of the table will show, 
_first, that the afferent or sensory fibers going to the muscles of 
the thigh are from 45% to 3.8% of the number of the cutaneous 
nerve fibers, while the excess of the muscular nerves of the 
thigh over the calculated number of motor fibers, is from 
25.1% to 3.1% of the muscular nerve fibers. 
In the case of the shank, the calculations for afferent 
fibers going to the muscles gives from 52% to 37% and an 
excess of fibers in the muscular nerves of from 34.3% 
to 38.6%. 
TABLE XXVI. 
Comparing the calculated number of sensory fibers with the number 
observed in the cutaneous supply and the calculated number of 
motor fibers compared with the number observed in the muscular 
supply and giving in each case the number of fibers by which 
they differ as well as the percentage value of this number. ‘The 
observed numbers being used as the standards.
