Of the numerous attempts to reveal physiologic change associated with reaction in the schizophrenic group, one of the most consistently successful has been that concerned with basal metabolism or, as Hoskins1 more correctly designated it, heat production. According to numerous workers, heat production among schizophrenic patients is reduced, Hoskins' average for 214 male patients with schizophrenia being 88.3 per cent of normal. Walker2 found that 50 per cent of thirty patients with schizophrenia had an average basal metabolic rate of — 20, the others giving values within normal limits or slightly above it. Numerous other workers have reported similar findings (Bowman and Fry3 and Whitethorn and Tillotson4). The chief difficulty has been in securing sufficient cooperation to obtain the relaxation necessary for accurate results, so that the figures should probably be lower than those stated.
