1866 Henry Hyde Salter (1823-1871) added a kymograph to the spirometer in order to record time while obtaining air volumes. 1879 Gad J. published a paper entitled "Pneumatograph" that described a machine that allowed the recording of lung volume changes.
Palmer manufactured instruments like the kymograph, invented by the German physiologist Carl Ludwig in 1847, the Stromuhr (another design by Ludwig) for measuring the rate of bloodflow and a 'dotting machine', designed by William McDougall to measure and record levels of fatigue. [2]
The man confessed that he knew better than to leave a dirty cup in a common area, but it had slipped his mind. He said he regretted having lied about it when caught. Hamm went in for the kill.
