Religious teachers and Bible readers are beginning to give this class over as past all remedy, until their physical condition is improved. Their intellects are so blunted and their perceptions so perverted by the noxious atmosphere which they breathe, and the all-pervading filth in which they live, move, and have their being, that they are not susceptible to moral or religious influences. In London, some of the city missionaries have entirely abandoned the tenant-house class. There is, undoubtedly, a depraved physical condition which explains the moral deterioration of these people, and which can never be overcome until we surround them with the conditions of sound health. A child growing up in this pestilential atmosphere becomes vicious and brutal, not from any natural depravity, but because it is mentally incapable of the perceptions of truth. Most truly does the Inspector of the Fourth Ward say: [Sidenote: Tenant-House Cachexy] “There is a tenant-house cachexy well-known to such medical men as have a practical acquaintance with these abodes; nor does it affect alone the physical condition of their inmates. It has its moral prototype in an ochlesis of vice--a contagious depravity, to whose malign influence the youthful survivors of the terrible physical evils to which their infancy is exposed, are sure to succumb. We often find in persons of less than middle age, who have long occupied such confined and filthy premises, a morbid condition of the system unknown elsewhere. The eye becomes bleared, the senses blunted, the limbs shrunken and tremulous, the secretions exceedingly offensive. There is a state of premature decay. “In this condition of life the ties of nature seem to be unloosed. Maternal instinct and filial affection seem to participate in the general decay of soul and body. A kind Providence, whose hand is visible even here, mercifully provides that the almost inevitable decay and death which man’s criminal neglect entails on the offspring of the unfortunate who dwell in these dreary mansions, shall elicit comparatively feeble pangs of parental anguish. To the physical and moral degradation, the blight of these miserable abodes, where decay reigns supreme over habitation and inhabitant alike, may be plainly traced much of the immorality and crime which prevail among us. The established truth, that, as the corporeal frame deteriorates, man’s spiritual nature is liable also to degenerate, receives its apt illustration here.” [Sidenote: Prevailing Diseases]
