Note 10 — FRANCIS A. LEYLAND.

The condition into which Branwell fell at this period is one very well-known to mental physiologists. Thus Carpenter speaks of it: 'In most forms of monomania, there is more or less of disorder in the ideational process, leading to the formation of positive delusions or hallucinations, that is to say, of fixed beliefs or dominant ideas which are palpably inconsistent with reality. These delusions, however, are not attributable to original perversions of the reasoning process, but arise out of the perverted emotional state. They give rise, in the first place, to misinterpretation of actual facts or occurrences, in accordance with the prevalent state of the feelings.'—'Principles of Mental Physiology,' (1874), p. 667.
