Pulmonary Veins. -- From this net-work of arteries and air sells the radicals of the pulmonary veins arise, and, coalescing into larger and larger branches, at length accompany the arteries and return the blood to the left auricle of the heart in a purified condition. The pulmonary arteries and veins differ from the same vessels in the other parts of the body, since the former conveys the innocent blood, and the latter arterial blood.

I stopped on this short paragraph as I approach some larger sections. This segment again makes a reference to the word "net-work" in a style that is now out dated. The next section takes us into Breathing and then lung capacity.

• Giving up of Oxygen
  
  

  Before I begin this next section, I wanted to point out the title it has a most curious title. I can’t wait to figure learn what it might mean. It sounds as if someone might give up an addiction, however I believe that addiction was not understood 90 years ago as it is today. Although people did work to give up ‘vices’ that today are known to be addictive such as alcohol, tobacco, opiates and other items.
  

  Giving up of Oxygen. –the atmospheric air laden with its life-sustaining property, oxygen, having passed in to the lungs, gives up that vital element and receives in its place the carbonic acid gas, water, and other refuse materials which the blood is picked up in its journey through the body, and which are no longer fitted to circulate in the blood and preserve the vitality of the body. No tonic invigorates so well as a few, deep, full inspirations of pure, cold air.

  ________________

  well I didn’t expect what I received in that section. The last sentence though definitely sounds a little bit hokey. Older maybe invigorating, but that doesn’t certainly make it healthy. It just makes a cold.

  Oddly there are a few unscientific studies that have been circulated over the last decade or two that offer a contrarian exception that heat therapy might actually be good for a person that is sick. I suspect that the correct answer is that the body needs or prefers a stable temperature that is neither too hot nor too cold in order to remain healthy or regain health.

• Lead Poison in Rural Districts
  
  

  Lead Poison in Rural Districts. — in rural districts, on the other hand, whenever Rainwater is used for drinking purposes, it is exceedingly liable to be contaminated with lead from lead lined cisterns, led service- or collection-pipes, lead ropes, or from the solder of tin roofs. As a rule, the purer the Rainwater, the greater is its action on lead with which it stands in contact; hence, therefore, the presence of a minute quantity of some salt of sulfuric acid and water is of very great importance, and serves as an invaluable protection against lead poisoning to the human beings and animals who may employ it for drinking purposes.

   

   

  There are many sources for lead poisoning, chief among them is typically lead based paints.  However, today people also run the risk of exposure to heavy metals through many batteries from all those devices that require Nickel Cadmium or Lithium Ion batteries.  We don’t always think about what is going into our environment when we’re putting more laptop memory in a computer or buying a spare battery, not to mention all the cell phone batteries churning through landfill dumps each year.

• Diet Pill Support Groups
  
  

  Here is an interesting concept.  You have probably heard of weight watchers which brings people together in a support group like setting and teaches them to assign points to the food they eat.

  The PhenForum is a support group for women that use Phentermine diet pills.  They can come together and share their views and lessons learned about dieting, losing weight and diet pills. 

  Unlike Weight Watchers that is one part support and one part dietary education, the PhenForum mixes support group methods with the power of diet drugs.  Many times people receive a prescription for a long term drug and do not get to share notes with other patients.  They are completely at the mercy of their doctor.

  That’s not entirely bad, but sometimes it helps to see how the drug is impacting, helping or hurting other people.  In this regard the PhenForum provides a useful social setting where people taking this prescription drug can share knowledge about their conditions as well as the drugs they are taking to alleviate that condition and lose weight.
