“When,” as the Times newspaper put it some time ago, “it is considered that water constitutes nearly three-fourths of the entire weight of the animal body, that it is the basis of all beverages, and the solvent by means of which all food is assimilated and all secretion is performed, the importance of obtaining it in a state of purity would seem to require no further demonstration. Unfortunately, however, although the facts have for a long time been universally admitted, the practical conclusions to which they would lead have comparatively seldom been acted upon. Not only do we obtain the greater part of our supply of water from that which has already washed the earth, but we have permitted water flowing in its natural channels to be everywhere utilised as a carrier of the worst descriptions of filth.” All in fact must see on a little reflection that however excusable certain things might have been at one time they are no longer so under the light thrown upon them by deep and long-continued investigations by scientific men who have devoted much study to the subject. All must know that no proper supervision has up to the present been taken, and nothing like proper compulsion has been applied to the removal of glaring evils. Let those who are apathetic on this subject ponder the following, taken from a paper read a short time since before the Society of Arts by J. J. Pope, Professor of Hygiene to the Birkbeck Institution. The author said:— “it is a startling fact that one-fourth of the children born into this world to endure for threescore years and ten, die before they attain the age of five years. This is a sad truth, and the more lamentable when we know that these deaths mostly arise from causes that are quite preventible.” The same author said, and said truly, that: “Very few people, indeed, consider the subject of their own health, until warned by a present attack of sickness, through failing to acknowledge the true worth of science and medicine, which is far more preventive than remedial. Can it be doubted that it is better and wiser to abolish the cause of disease, to prevent its appearance, than to wait for its attack and cure the result?” As regards houses: some have been built without reference either to light, air, or dryness. Some have been made out of cattle-sheds, cabins, and stables, and are far worse than prison cells or workhouse wards. These damp dark dungeons lower the temperature of the body, decrease the strength, generate disease, cause rheumatism, and predispose to other evils, not the least of which is consumption. We have it on the authority of the highest medical men that with proper sanitary objects attained a reduction of nearly half the present premature disability from sickness, and mortality due to conditions about their dwellings may be obtained.
