At Gee-Gee's order, Jerry Lipton ran through the check procedures again. This time Rick and Gee-Gee carefully watched the functioning of each servomotor. Finally Gee-Gee announced that he was satisfied. Next step was to check the spacemonk's instruments' circuits.
Rick picked up a tiny stethoscope. It would be taped to the monk's body, held tightly to his heart. He traced the circuit to where it disappeared into the oscillator switch, then took the walkie-talkie. "Display on? Checking the stethoscope."
"Go ahead," Earle replied.
Rick held it to his own heart for a few minutes, then tapped on the bell with his forefinger.
"Looks good on the display," Dick's voice came back. "What did you hit it with—a hammer?"
"Finger," Rick said. "Let's take a temperature next." He found the thermocouple that would be attached to the marmoset's body, traced the circuit to the oscillator, then called, "Watch my own body heat." He tucked the sensing element under his armpit.
"Hotter than a pistol," Dick said.
"Why? Do I have a fever?"
"Not unless you're a monkey. Next?"
"Sphygmomanometer. And don't worry about the pronunciation. The blood-pressure cuff." He traced the circuit, then inflated the rubber and fabric cuff.
