With regard to the sleeping apparel, there is no doubt the modern pyjamas are a great improvement on the old-fashioned bedgown. They are more thoroughly protective to the skin, and keep the extremities uniformly warm, which the latter fails to do. They are better made of flannel, thin in summer and thicker in winter. Persons who are in the habit of wearing woollen material next the skin during the day should certainly keep to the same at night, otherwise the change is too great, and there is thus great risk of taking a chill. The flannel under-garment which has been worn during the day can then be taken off at night without any danger, and has the opportunity of being aired. It might hardly seem necessary to refer to this fact, namely, that the under-garment which has been worn during the day should be taken off at night. Yet I can only say that instances in which this particular garment is never taken off at all, but is worn continuously both night and day, perhaps for a whole week at a time, are not altogether so rare as they might be. In conclusion reference may be briefly made to a subject which is probably within the experience of everyone. There ale many people who pride themselves on not requiring any extra clothing during the colder months, and evidently look upon this fact as a proof that they possess Spartan powers of endurance, and that cold is a matter of perfect indifference to them. Now, it may be that a few individuals differ essentially from the rest of humanity, and do not require any change of clothing all the year round. But the majority of people who profess this disregard to climate certainly appear as if they would be all the better for warmer material, for their faces look pinched and their hands seem nearly frozen with the cold. But the fact is that even if the want of thicker clothing is not particularly felt during the cold weather, it is always wiser to wear an extra allowance, for the heat of summer can be endured better if this principle is carried out. If a common-sense view of the matter is taken, then it will be readily apparent why it is desirable to wear plenty of warm clothing during the colder months. CHAPTER VI. DIET The larger part of this work is taken up with a consideration of the most suitable diet for those living in Australia. In this way a greater restriction in the amount of butcher's meat is counselled, while a more widely extended use of fish, vegetables, and salad plants is advocated. And as far as beverages are concerned, Australian wine of a low alcoholic strength is recommended as being the most natural beverage for every-day use. But there are a few other matters connected with food, and drink, and daily habits which will deserve some little reference, and accordingly they will be dealt with. These are fruit, tea, coffee, iced drinks, and the use of tobacco. All these are important enough to merit notice; indeed, they are subjects possessing more than usual interest.
