side, while in the side that had not been masseed there were 

 abundant evidences of neuritis, and perineuritis exerting destruc- 

 tive compression upon the nerve fibers. The perineurium, or 

 sheath covering the bundles of nerve fibers, was at least three 

 times as thick in the non-masseed side, and the connective tissue 

 around the perineurium was also thickened with numerous new- 

 formed cells. The small vessels in the perineurium were also the 

 seat of a peripheral hyperplasia or thickening. The lesion of the 

 nerves was more marked than that of the vessels. 



These experiments of M. Castex give more emphasis than ever

In Fig. 4 all the nerve elements arc of normal appearance, while the nerve elements from 

 the non-masseed side — Fig. 3 — show that the perineurium is thickened, and underneath this 

 there are deposits of new-formed connective tissue which crowd and compress the nerve fibers.

 the buttocks as far as the feet, and the shoulder blades as well. 

 And when they seem to have had enough, lift her up by the tail, 

 and, having given her a stretching, let her go. And she will 

 shake herself when let go, and show that she liked the treatment.*'
