About the action of peptone on the mentally ill

The remarkable fact that sometimes an acute infectious disease proceeding with symptoms of fever has a curative effect on the mental illness existing in the sick person has long been known in the specialized literature, but we still do not have a satisfactory explanation of such a curative effect. This state of the matter is easily understood if we imagine the difficulties of explaining the effect of fever: on the one hand, healings that occur as a result of an accidental illness with an acute infectious disease are still extremely rare, since we usually observe that such diseases occur without the slightest effect on the state of mind. patient, and on the other hand, infectious diseases, to which a beneficial effect on psychosis is attributed, by their very nature is very different, for example. typhoid-diphtheria-malaria, so that the curative effect obviously does not depend on the specific effect of this infectious disease.
