Show Til K TRt'B THEORY , AUOlT FUESII AIK. j The following facts on "open windows win-dows at niht" is from Ial's Journal of lhallh: Very much has been written on this subject, and written unwisely; the facts : arc that whoever sleeps uncomfortably cool will get sick. To hoist the window ! sky high when the mercury is at zero is an absurdity. The colder a sleeping apartment is the more unhealthy docs i it become, because cold condenses the carbonic acid formed by the breathing j of iho sleeper. It settles near the i floor, and is rc-breathed, and if in a ! very condensed form he will die bclore : morning. Hence he must be governed by circumstances: the first thing is, ' you must be comfortably warm during i sleep, otherwise you are not rcfrenhe i, land in flam mat ion of the lungs may be i engendered, and life destroyed wuhin a very few days. An open door and an open fire place are sufficient for ordinary ordi-nary purposes in cold weather. When other windows are opened, it is to have them down at the top two or three inches, and up at the hotf.m for the same space, in miamic localities locali-ties ond these are along the water coun-e, beside mill Kinds, marshes, I bivouac rivr bottoms, flat islands, and the like. It L the most important import-ant from the fir.t of Angut until severe se-vere frot-! have been noticed, to tleep with all external doors and windows closed, U?eause the cool air of sunset causes the condensation of the pion-ou3 pion-ou3 emanations which were caused bv the heat of noonday sun to rise far above the earth. 'J'hi condensation makes the air "heavy"' by the great solidification of the emanations by cold; these resting on the surface of the ennh in the more concentrated and oinlirnant form, thyare breathed into the luii" and swallowed into the Mnm-aeh, Mnm-aeh, corrupting anil poisoning (lie . blood wiih gn-ai rapidity.

The general lessons les-sons are: first, avoid exposure, to j the outdoor air in miasmatic localities t for the hoursineludingsunriseand sun- set. Second, having a blazing fire on the hearth of the family room at these hours to rarity and send the miasma upward. Third, take breakfast before going out oi doors in tho morning, and take tea before sundown; then being , out at night is not so injurious. |
