Invalids are advised to put on a Great Coat when they go out, and the temperature of the external air is not higher than 40. Some susceptible Constitutions require this additional clothing when the Thermometer falls below 50; especially at the commencement of the Cold weather. A GREAT COAT must be kept in a Room where there is a Fire,--if it has been hung up in a cold damp Hall, as it often is, it will contribute about as much to your Calorification,--as if You wrapped a Wet Blanket about You. _Clothes_ should be warm enough to defend us from Cold[43],--and large[44] enough to let every movement be made with as much ease when they are on,--as when they are off. Those whose employments are sedentary,--especially hard Students--who often neglect taking sufficient Exercise[45], suffer extremely from the pressure of tight _Waistbands_--_Garters, &c._ which are the cause of many of the mischiefs that arise from long sitting--during which they should be loosened. _Braces_ have been generally considered a great improvement in modern dress--because they render the pressure of the Waistband unnecessary, which when extremely close is certainly prejudicial--but we have always thought they have produced more inconvenience than they have removed--for if the inferior Viscera get thereby more freedom of action--the superior suffer for it--and, moreover, _Ruptures_ are much more frequent--the Girdle which formerly prevented them being removed,--and, instead of that useful and partial horizontal pressure, in spite of the elastic springs which have been attached to the Braces, the whole body is grievously oppressed by the Vertical Bands. The best material for Breeches, is the elastic worsted stocking stuff. _Tight Stays_--and _Braces_--obstruct the circulation of the Blood, &c. are the cause of many Chronic Complaints, and often create Organic Diseases[46].

"After the age of 35, it may be better to exceed, rather than be deficient in clothing."--ADAIR'S _Cautions_, p. 390. Cold often kills the infirm and the aged, and is the proximate cause of most Palsies;--it is extremely desirable that Bed and Sitting Rooms for Winter occupation, should have a Southern aspect--when the Thermometer is below 30, the proper place for people beyond 60, is their own Fire-side:--many of the disorders and Deaths of persons at this period of Life--originate from irregularity in Diet, Temperature, &c. by Dining out, and frisking about, joining in Christmas Gambols, &c. in Cold weather.
