152 WONDERFUL X-RAf. 



Danger in the Ray. In order to secure a "skiagraph " of 

 any part of the body it is necessary to expose the parts for from one to 

 ten minutes, or sometimes fifteen minutes, to the action of the light or 

 x-ray. The person, of course, feels absolutely nothing of the effect of 

 the light, which is perhaps two feet away and enclosed in a glass case. 

 But in a week or so, especially after the longer exposure, the place 

 sometimes becomes sore, showing all the effects of a deep burn. The 

 sensation begins by an intense itching ; it soon becomes red and in- 

 flamed or even blistered and is very sore and slow to heal. It was 

 found, however, that by covering the skin over the place to be exposed 

 to the x-ray with glycerine no " burn " resulted. 



Diseased Organs Identified. When an oj-ray picture is 

 taken the bones and foreign metallic, glass or stony articles, show 

 clearly, but a shadow is also cast by the internal organs, and as these 

 differ in density, their outlines may usually be determined. Whenever 

 any organ is inflamed it will show a darker outline than normal. If 

 enlarged it will be apparent. Thus fevers may be recognized, tumors 

 located or rupture of the walls of an artery detected. By these means 

 medical treatment which was based upon guess-work, often wrong, may 

 be made positive, accurate and successful. If a clot is forming on the 

 brain the ic-ray will detect it and show the surgeon how to save the 

 patient's life. 



OBJECT LESSON OF THE EFFECT OF CIGAR- 

 ETTE SMOKING. 



The fearful effects of cigarette smoking upon the stomach and 

 lungs, as elsewhere illustrated, can scarcely be exaggerated. The 

 analysis of the material composing the cigarette, made by prominent 

 chemists and physicians, proves that opium, the extract of tonka 

 beans (which contain a deadly poison), and other injurious substances 

 invariably are used in the manufacture of an acceptable cigarette. 

 What is known as "Havana flavoring" (tonka bean extract), is sold 

 by the thousand barrels. The wrappers, which are popularly known 

 as rice paper, are never made from rice, but, on the contrary, either 

 from common paper, which makes the poorer grades, or from rag 

 scrapings bleached white with arsenic, which makes the better grades. 

 It is all cheap, but chemically foul and highly injurious. Cigarette 

 smoking ruins the memories, the health and the morals of millions of 

 boys throughout our country because of the sediment of poison which 

 it deposits in the lungs and stomach and thence into the blood and 

 brain. 



Such eminent physicians as Sir Morell Mackenzie of London, 

 England, Dr. Hammond, Dr. Sayre and others, have described such 

 mai-auies as heart disease, cancer, epilepsy and insanity as directly due 

 'to the peculiar insidious poison from cigarettes.
