It has been supposed by some that tea and coffee have, at least, a degree of nourishing power. But it is proved that it is the milk and sugar, and not the main portion of the drink, which imparts the nourishment. Tea has not one particle of nourishing properties; and what little exists in the coffee-berry is lost by roasting it in the usual mode. All that these articles do, is simply _to stimulate without nourishing_. Although there is little hope of banishing these drinks, there is still a chance that something may be gained in attempts to regulate their use by the rules of temperance. If, then, a housekeeper can not banish tea and coffee entirely, she may use her influence to prevent excess, both by her instructions, and by the power of control committed more or less to her hands. It is important for every housekeeper to know that the health of a family very much depends on the _purity_ of water used for cooking and drinking. There are three causes of impure and unhealthful water. One is, the existence in it of vegetable or animal matter, which can be remedied by filtering through sand and charcoal. Another cause is, the existence of mineral matter, especially in limestone countries, producing diseases of the bladder. This is remedied in a measure by boiling, which secures a deposit of the lime on the vessel used. The third cause is, the corroding of zinc and lead used in pipes and reservoirs, producing oxides that are slow poisons. The only remedy is prevention, by having supply-pipes made of iron, like gas-pipe, instead of zinc and lead; or the lately invented lead pipe lined with tin, which metal is not corrosive. The obstacle to this is, that the trade of the plumbers would be greatly diminished by the use of reliable pipes. When water must be used from supply-pipes of lead or zinc, it is well to let the water run some time before drinking it and to use as little as possible, taking milk instead; and being further satisfied for inner necessities by the water supplied by fruits and vegetables. The water in these is always pure. But in using milk as a drink, it must be remembered that it is also rich food, and that less of other food must be taken when milk is thus used, or bilious troubles will result from excess of food. The use of opium, especially by women, is usually caused at first by medical prescriptions containing it. All that has been stated as to the effect of alcohol in the brain is true of opium; while, to break a habit thus induced is almost hopeless, Every woman who takes or who administers this drug, is dealing as with poisoned arrows, whose wounds are without cure. The use of tobacco in this country, and especially among young boys, is increasing at a fearful rate. On this subject, we have the unanimous opinion of all medical men; the following being specimens.
