118 ELEMENTARY PHYSIOLOGY. 



tween the beats is diminished, which must be injuri- 

 ous to that important organ. With the increased 

 activity of the heart, comes an increased rapidity 

 of the flow of blood through the blood-vessels- 

 The blood is forced to the surface, which becomes 

 flushed, and, if long continued, the blood-capillaries 

 at the surface lose their power of contraction, and 

 the drunkard's nose is the result. 



As in the kidneys, the tissue of the heart-walls 

 will degenerate and change to fat. A fatty coat 

 may run back from about it, and it is known as fatty 

 accumulation. If the use of alcohol is continued, 

 the heart will finally succumb; its fibers will become 

 relaxed, its cavities become enlarged, it will entirely 

 lose its power to contract, and death will ensue from 

 paralysis of the heart 



Sometimes the heart continues its efforts to expel 

 the blood, even when the cavities have increased 

 their capacity, and the walls become thin and weak. 

 Alcoholic rupture is then likely to occur. The effect 

 on the appearance of the nerves, eye and blood- 

 vessels is shown on the Aid.

 human system just mentioned in these lessons, let 

 us recall briefly what it will not do, and then resolve 

 never to use it except as a medicine, and then only 

 when directed to do so by a competent physician. 

 Following are a few of the many facts concerning 

 alcohol, which have so frequently been demonstrated
