A better understanding of the relation of sanitary science to daily life would also facilitate some of the painful steps which must inevitably be taken, in order to bridge the gulf set between the feudal methods of the past and the modern problems of domestic service. That the isolation from her kind of a "general" servant predisposes to anæmia is stated as a fact on good authority, but it is certainly not generally known. That absence of opportunity for recreation or social intercourse has led and may lead again to deception, if not to worse, is recognised unwillingly, if at all. That human nature is physiologically similar, however diverse its external appearance and standards, is very hard to realise or to act upon; so the fact that suitable provision for bathing and wholesome sleep by dependents is not always made, is apt to be ignored on economic grounds; and the resultant complications are assigned to any but their real cause. The solution of another of the acute problems of the day depends upon the women also of this country. I refer to the character of the influence, an influence of the most intimate, to which young children are subjected during infancy. In addition to vulgarities of conduct or enunciation, actual moral harm may be suffered from want of care in the choice of a child's attendant. Bad habits, impossible to eradicate, are to be traced to this source only. Their hygienic import calls for no further stress. Their prevention rests entirely with the child's parents. Another illustration of the need for a better acquaintance with hygiene is found in the general custom of entrusting the preparation and care of the daily diet to empirically prepared, ill-informed, young women. Ascertained facts in connection with, for instance, "typhoid carriers"[126] should have surely created almost a panic in the households of England; but it is rare to learn that even one mistress has inquired into the personal habits of her cook, or that she has concerned herself personally in the cultivation of most careful attention to necessary hand-washing by her household. A mere tyro in sanitary science would take warning and be on her guard against this and other disgusting and preventable sources of domestic infection.
