=Insanity.=--No accurate tabulation of results in different forms of insanity has been made. Numerous successes, interspersed with fewer failures, have been reported. The author has both succeeded and failed with acute dementia, but the failure was a twenty-four-hour trial only, and included but three adjustments. =Intestinal Obstruction.=--The prognosis of intestinal obstruction from intussusception or strangulated hernia is, under Chiropractic, bad. Such cases are almost surely fatal unless operated. Faecal obstructions or masses of worms, also volvulus, respond quickly and prognosis is good. Careful diagnosis is required before taking a case of apparent complete obstruction. =Irritable Heart.=--If purely nervous, recovery is quick and easy. If there is a drug diathesis or organic disease, slow and doubtful. =Jaundice.=--Yields readily, but if of the obstructive form the obstruction must first be reduced or removed by adjustments. =Laryngitis.=--A few adjustments suffice for simple acute cases. Specific laryngeal infections are more difficult. Laryngitis with ulceration, which is either syphilitic or tubercular, may not recover or may recover after a protracted struggle. Chronic laryngitis of other forms is curable, but requires more time than acute. =Leucorrhoea.=--Fair prognosis only. =Lumbago.=--Good, unless pain prevents proper adjustment. True lumbago is quick to respond. =Malaria.=--Tenacity varies according to climatic conditions. Malarial cachexia always yields slowly, sometimes defies adjustment altogether. No reports are to be had on pernicious malaria. Other forms recover though paroxysms tend to recur several times before checked, but of shorter duration than if no adjustment is given. =Mastoiditis.=--Good results in the few cases observed. =Measles.=--Excellent. Recovers quickly. Eruption hastened by early adjustment, runs very mild course with little or no fever, catarrhal symptoms disappear early. No sequelae. =Meniere’s Disease.=--Labyrinthine disease of this character has been cured, without reported failures, but data is meagre, not more than three or four cases having come under the author’s notice. =Menorrhagia--Metrorrhagia=.--Results excellent, and usually quick. One fifty-two-hour intermenstrual hemorrhage from uterus was stopped in one hour by adjustment, with no recurrence. =Migraine.=--Migraine, or hemicrania, gives a fair prognosis only. Most cases require a long course of adjustments. =Movable Kidney.=--Prognosis good, but change of position and complete fixation slow. No treatment required--merely adjustment. =Myelitis.=--Transverse myelitis, if adjusted in the acute stage, may be checked as any other inflammation, and the damage and resulting paralysis will be greatly lessened or altogether prevented. The paralyses which follow myelitis require time for the rebuilding of the degenerated axons whose course is interrupted at the diseased area, but tend to recover.
