This paper is the continuation of a study reported by Finesinger in 1939. In this he conducted a series of experiments in which psychoneurotic and 'normal' individuals were attached to the Benedict-Roth basal metabolism apparatus for the purpose of recording their spirograms and calculating their minute respiratory volume, which is the product of the rate of respiration and the depth of respiration. While recording the spirograms it was suggested to them that they think of unpleasant ideas and later that they think of pleasant ideas. Twenty-seven patients in Group One with diagnoses of hysteria, phobia, or anxiety neuroses all showed much greater changes (increases) in their minute volumes than did the eleven patients in Group Two who had diagnoses of hypochondriasis, reactive depression and compulsion neuroses. The reaction of the normal group was intermediate between these two. The experiments reported in this paper were conducted in the same way except that instead of ideational stimuli, physical stimuli were used. These consisted of intracutaneous injections of saline, pin pricks, and local electric shocks. The minute respiratory volume was again used as the main index of the respiratory response. After the administration of the pain stimulus the patient was asked to think of it ('recall period'). In addition to the change in minute volume the amplitude of the respirations, average oxygen consumption and percentage of points and rounds at expiration were noted. Again much greater changes predominantly in the direction of increase were observed in Group One than in Group Two. The control group (fifteen) was slightly more reactive than Group Two but much less than Group One. The paper presents a clear precise study of the respiratory changes upon the application of painful stimuli and of the patient's recalling the stimulation.
