| Show DISEASES Of o THE CHEST AND MANY CAUSES Dr Horace Dobell at one time timo senior physician in the thc Royal hospital in London London Lon Lon- don and a n. bl high h authority on diseases of the tho chest has enumerated what ho bo considers con con- alders siders tho the most common causes canses of ordinary or or- dinar colds In 21 per pcr cent of the cases eases he investigated the Hie cause was sudden sud sud- den change of temperature Fo Fogs s anit damp air were the cause of l 19 10 per pcr percent cr cent cold win winds s in 10 per cent gettin getting getting get get- tin ting wet in in 14 1 per cr cent and rind wet feet in in 17 Ii per cent In tho the remaining 3 pe per pcr percent cent the causes could not be traced trace says san the tho New York World The above statements were ma made o b by tho thai patients who may have bc boon been en mis mi mis- mis taken For example a cold may develop de do- after ex exposure or after getting Jettin wet vet when neither er the tho exposure nor tho wetting is responsible for it While Whilo other authorities agree with the opinIon opinion lion Ion of Dr yet the question reI remains re- re I mains maing Are Aro these true causes of colds coMs 7 i I For one may mav get ct wet and chilled chille I through or ho lJ may Inay expose himself himl to I cold rold ol winds and amid damp air nir and still not tak cold These uncomfortable conditions condi condi- then sometimes do do but often donot do donot not produce bad effects The consensus of opinion today seems to bo be that colds are of disturbances of tho the circulation cir cir cir- brou brought ht on OD often though not invariably in by exposure to cold and aud wet wot and mind that these disturbances lend teut to produce inflammation in the tile weakest part of tho the respiratory apparatus Heat Hoat tho the Chief Cause Causo i In tho writers writer's opinion the time chief causes causes of col colds s are aro heat which heat which is especially es es- es dangerous in winter and winter and suddon sud sud- den don changes chantes of temperature If It one could aVOl avoid hot bot rooms and bid bad air air in winter ho would rarely tako take cold Sedentary Sed Sed- employment renders one ono peculiarly liable to colds on account of its depressing effect on the circulation tion u hen len ones one's occupation necessitates hl his sitt sitting D still for several hours he be should not bo be very cry heavily clad and the temperature tern tern- of the time room should bo be 70 or 12 degrees Fahrenheit then on going goin out into tho the cold ho lie should not only don IOn warm outer clothing but Lut should walk briskly to quicken his tion tiou As the action neither of the thc air nor of the water will rust iron while whilo their I combined action will wiIl so are coI colds tl I caused neither by heat beat nor b by cold but rather b by a sudden transition from froni either rither to the other While it will be conce conceded ed as a We well known fact that a sudden transition from rom heat beat to cold may cause a cold coM yet the further contention that transition transition transi transi- tion from col cold to heat beat lOa may equally I cause a cold will in some somo quarters be bo disputed Nevertheless tho the latter statement state state- I ment meat i is l logical if it is a fact that colds come como from toni disturbances of the circa circa- lation Tho Yi vigor or of the circulation is proportional within limits to tho the temperature tern tem of the tho air nir that acts nets on it Tho Time mechanical arrangements In the thu body hotly for maintaining animal heat adapt themselves to the surrounding tempera tare hue and when it chanS changes change's s suddenly whether from heat or cold or from cold to heat bent tho the c circulation is disturbed dis us- us and may mav produce n a cold old Tho The above theory proved practically true in tho following instance Tomen Two To men loon crossed crossel tho the Atlantic ocean in au an open boat The Time voyn voyage e lasted several months month during that time timo storms were encountered and the men while laboring labor labor- lag ing ut the oars were often oCten exhausted wet and chilled through yet ct throughout through through- out tho the whole of ot their trying experience ence neither caught cold But when having int arrived safe on tho the other si side e. e the tho they sought bought shelter and got ot thoroughly warmed both oth developed very heavy colds The reason that tho the colds developed developed developed de de- de- de after and not during tho the exposure ex ex- may have been that when the hot blood which tho the cold win wind and water had forced back to the internal organs suddenly returned under the tho iu- iu of warmth to tho the so lon long depleted depleted de de- de- de surfaces it set Ht up an inflammation that manifested itself as 35 asa asa a cold cold cold-a a striking t instance of the effect ef
