"Well, do it my way then!"
Cal fumbled for the needle and then with a steady hand he broke the glass ampule and filled the needle. "Is this still good?"
"It never deteriorates in a vacuum. We must chance everything."
Cal inserted the needle and discharged the contents. His face was gray.
"Now," said Tinker. "I'm immobilized completely from the shoulder blades down and can't harm myself. Cal, find the library and locate the reel that will deal on vertebra and spinal operations."
"How do you know it is here?" demanded Cal.
"It's listed, in Murdoch's diary. Now quit arguing and go!"
"How come this diary isn't common knowledge?"
"Because too many prominent people did not want their names mentioned as fostering Murdoch's surgery. Their offspring have never known about it and the medical profession has been keeping it under their hats so long that it has become a habit like the Px mark."
Cal located the library and consulted the card file. He returned with a reel of film. He inserted the reel into the operating room projector and focused it on the screen.
