A flannel under-garment reaching from the neck well down to the hips should always be worn, and in summer it may be of a thinner material than in the cooler weather.  It is better to have four made, so that two can be washed at a time.  In this way two can be in use every week, changing them day by day, so that one is getting thoroughly aired while the other is being worn.  The one which is being aired should be turned inside out, so that the part which has been in contact with the skin becomes thoroughly purified.  It must be remembered, however, that flannel is very liable to shrink from repeated washings.  This may be provided for by taking care that the under-garment, when first obtained, is several sizes too large.  In fact, it can hardly be too large at first, especially in the case of the thicker one for the cooler months, which shrinks much more proportionately than does the thinner one for the hot season.  This shrinking, however, can to a great extent be presented by paying attention to the following points:  These woollen under-garments should be washed by themselves not with any other clothes, in only moderately hot water.  Next, while they are still damp, and before becoming dry, they should be thoroughly stretched upon a table and then well ironed out.

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
