Nathan, in this "elementary manual of psychiatry," presents the material in three groups: (1) the nonorganic diathesis-like psychoses (as urged by Dupré in 1906); (2) the organic ones, and between the two (3) some symptomatic and toxic-infectious and visceral and endocrine disorders. The first group is treated under the following headings: emotional psychoses (simple, delusional and stuporous melancholias, and mania), the psychasthenic diathesis and psychasthenic syndrome, the mythomanic diathesis and mythomanic psychoses, the schizoid diathesis and schizoid psychoses, the paranoic diathesis and systematized delusional states or monomanias of Esquirol, and the perverse diathesis and instinctive perversions discussed according to Dupré's conceptions. There follow the hallucinoses of Séglas and Dupré, sensory, psychic and psychomotor hallucinations, and the hallucinatory psychoses, mental confusion, catatonia, catalepsy (both described as disorders of "auto-conduction"), epileptic mental disorders, neurasthenia, hysteria and mental anorexia (Sollier).
