![Ballet, and by Seglas, Avho, in a recent memoir, divides hallucinations into psycho-sensorial and psy- clio-motor (verbal, visual and auditory), according as the sensory or the motor centres of the cortex are involved. A Russian physician, Dr. Kandinsky, who sutt'ered from an attack of lypemania, analyzed in himself the mechanism of hallucinations, and also attributes them, conformably to Meynert's theory, to a subjective or autoinatic stimulation of the cor- tex of the anterior lobes of the bruin. Hallucinations without Insanity.—Like de- lusions, hallucinations are only symptomatic elements of insanity, and do not, by themselves alone, consti- tute it. Moreover, hallucinations may, in some cases, exist without insanity, and sane persons are subject, especially at the moments of passage between sleep- ing and waking, to hallucinations which they appre- ciate very sanely (hypnagogic hallucinations). Nevertheless these phenomena have been incorrectly called physiological hallucinations. A hallucination is always a morbid phenomenon; it is only its inter- ])retation that can be either physiological or patho- logical. Hallucinations occur in many forms of insanity, and it is not possible to separate a s])ecial type under the name of hallucinatory insanity. Tliey are esjjeci- ally frequent in melancholia, persecutory insanity, toxic insanities, etc. Hallucinations of Hearing.—Auditory hallu- cinations are most frequently met with in insanity.](https://iiif.wellcomecollection.org/image/b21963009_0087.jp2/full/800%2C/0/default.jpg)
