would conduce beyond all estimation to the physical, social, and moral improvement of that class. * * * * * Secondly, and as a matter of even higher importance, I would beg you to consider the incalculable good which may be conferred on the poorer classes of society, by the direct educational influence of those in better and more enlightened circumstances than their own. When I say that all the social errors to which I now more particularly refer, would gradually but swiftly vanish under the influence of education, I do not mean that the cure would lie in learning to read and to write and to sum:--though these attainments, of course, would largely increase the power, usefulness, and market value of their possessor. The education to which I refer, as an all-important influence for sanitary progress, is that which would consist in exhibiting to the lowest classes of society frequent practical evidences of the attainability and the advantages of higher civilization; an education which, by model and examples, would lead them to know cleanliness from dirt, decency from grossness, human propriety from brutish self-abandonment; an education which, by sensible experience, would teach them to feel the comfort and the profit of sanitary observances, and would apply their instinct of self-preservation to the deliberate avoidance of disease. It is in this point of view, gentlemen, that I would solicit your attention to the useful and philanthropic exertions of three societies which have been established during the last few years, with the object of improving the condition of the labouring classes; and I would venture to suggest that the course which those societies have adopted in various parts of the metropolis, is one that might with the utmost advantage be pursued within the City of London. The establishment of _Model Dwelling_ and _Lodging-houses_, and of _Public Baths_ and _Laundries_, for the use of the labouring population, is now no longer a matter of recent speculation. Under the beneficent auspices of the Societies to which I have referred, the following experiments have been tried:--
