erangement is accompanied with more or less of excitement. Sometimes the excitement amounts to a fury. The individual in such cases is subject to hallucinations and illusions. He is impressed with the reality of events which have never occurred, and of things which do not exist, and acts more or less in conformity with his belief in these particulars. The mania may be general, and affect all or most of the op-era tions of the mind; or it may be partial, and be confined to particular subjects. In tbe latter case it is generally termed 'monomania.'** In a more popular but less scientific sense, “mania” denotes a morbid or unnatural or ex-cessive craving, issuing in impulses of such fix-ity and intensity that they cannot be resisted by the patient in the enfeebled state of the will and blurred moral concepts which accompany the disease. It is used in this sense in such compounds as “homicidal mania,” “dipsomania," and the like.—Hypomania. A mild or slight-ly developed form or type of mania.—Mono-mania. A perversion or derangement of tbe reason or understanding with reference to a single subject or small claas of subjects, with considerable mental excitement and delusions,^ while, as to all matters outs'de the range of the' peculiar infirmity, the intellectual faculties remain unimpaired and function normal y.

W. 21; In re Gannon’s will, 2 Misc. Rep. 329, 21 N. Y. Supp. 960.—Paranoia. Monomania in general, or the obsession of a delusion or sys-tem of delusions which dominate without de-stroying the mental capacity, leaving the patient sane as to all matters outside tbeir particular range, though subject to perverted ideas, false beliefs, and uncontrollable impulses within that range; and particularly, the form of monomania where the delusion is as to wrongs, injuries, or persecution inflicted upon the patient and his consequently justifiable resentment cr r^venee. winters v. State, 61 N. J. Law, 613, 41 Atl. 220; People v. Braun, 158 N. Y. 558. 53 N. E. 629; Flanagan v. State, 103 Ga. 619, 30 S. E. 650. Paranoia is called by Kraepelin “progres-sive systematized insanity,” because the delusions of being wronged or of persecution and of excessive self-esteem develop quite slowly, without independent disturbances of emotional life or of tbe will becoming prominent, and because there occurs regularly a mental working up of the delusion to form a delusionary view of the world,—in fact, a system,—leading to a derangement of tbe stand-point which the patient takes up towards the events of life.—Homicidal mania. A form of mania in which the morbid state of the mind manifests itself in an irresist-able inclination or impulse to commit homicide, prompted usually by an insane delusion either as to the necessity of self-defense or the avenging of injuries, or as to tbe patient being the appointed instrument of a superhuman justice.

An irre-sistible craving for alcoholic or other intoxicating liquors, manifested by the periodical re-currence of drunken debauches. State v. Savage, 89 Ala. 1, 7 South. 183, 7 L. R. A. 42B —Dipsomania. Practically the same thing as metho-mania, except that the irresistible impulse to intoxication is extended by some writers to in-clude the use of such drugs as opium or cocaine as well as alcohol.
