Examination. — Sept. 21, 1894 (155 days after second operation). 



(i) Stimulation of the peripheral ulnar just below the bone tube with 

 induction shocks at 8 ctm. S. C. gave flexion of the muscles supplied by the 

 nerve, together with signs of pain, as shown by the reflex movements ; this 

 after the median had been resected. 



(2) Stimulating central ulnar above bone tube at 12 ctm. S. C. excited 

 contraction of the muscles supplied by ulnar. 



(3) Stimulation of muscular branch to flex. carp. ul. at 8 ctm. S. C. 

 excited contraction of this muscle. 



(4) Stimulation of the ulnar at wrist gave no contraction and no 

 reflexes. 



(5) Cutting the nerve with scissors above the bone tube, below the bone 

 tube, and cutting muscular branch to flex. carp. ul. excited contraction of 

 muscles supplied by the nerve. 



(c) Implantation of Catgut Bundle. 



In the following series of seven experiments, threads of catgut, as 

 suggested by Gliick and Assaky, were employed to unite the ends of the 

 resected nerve.

Operation. — The ulnar of the right side was exposed, and 6 ctm. 

 removed. In place of the suture k distance, as suggested by Assaky, the 

 author, in this and five other experiments, employed a bundle of catgut

threads about i ctm. longer than the exsected nerve segment, and composed 

 of eight No. 3 chromatized threads about which were wound two very fine 

 catgut threads. The ends of the threads encircling the bundle were allowed 

 to remain long, so that they might be employed as sutures for uniting the 

 implanted bundle to the cut ends of the nerve. A bundle of catgut threads 

 thus prepared and made antiseptic by boiling for fifteen minutes in alcohol 

 and then washing in sterilized distilled water, was implanted and sutured 

 above and below to the central and peripheral ends of the resected nerve, 

 care being taken to have the ends of the several catgut threads composing
