 tion on the arm entirely failed, but a pustule appeared 

 on the wrist, which ran its course, with characteristic

 withdrawing it after the operation, and the pressure which 

 he made for a few minutes with his finger, and a linen 

 bandage which he applied, to heal the wound, contri-

 of the virus." P^o-^ 134 — 136.
