Saline Impurity. -- But any quantity of saline impurity exceeding thirty-five grains to the gallon renders a water unfit for the freest domestic use. Such water would be popularly designated as a very "hard" water, but a good deal of in difference is caused by the nature of the hardness, that due to sulfate of lime, and called the permanent hardness because it is not removable by boiling, being decidedly most prejudicial to health.

Okay so I'm going to admit freely that have no idea what this last paragraph was about. I understand what saline solution is, and I understand what hard water is.  But I do not understand how the two come together in this particular paragraph and what it might mean even in the context of the previous paragraph in section. I think progress like this that I wish I had found a 100-year-old golf digest talking about golf bags and techniques as opposed to a medical journal. :-)

• Combines Lightness and Strength
  
  

  But notwithstanding this diversity in form, the general plan constantly kept in view by the Divine Architect has been the central idea of combining lightness with the greatest possible degree of strength.  The bones of the arms and legs are round were triangular, and hollow, thus giving with the same weight a greater degree of strength that have solid, besides affording a larger surface for the attachment of muscles.

  This quick little section doesn’t make a lot of sense when you read the first sentence, you have to remember that they’re talking about bones.  The paragraph structure essentially of this section is what is slightly misleading.  My grammar school English teacher would criticize a writer for not providing a topic sentence at the beginning of the paragraph.

  Regardless they have hit on a novel last backed up the design of the human body, the design of bones.  There many fascinating aspects about the human body and the strength and weight of bones is definitely a topic that has been worthy of consideration and study for many years.  In some ways we have only recently begun to understand just how important the design of bones are in carrying mass and dealing with impact.  So in this case the writers actually touching on a very interesting topic even though they are doing that and a manner that is a hundred years out of date and slightly out of focus.

• Purity of Rain Water
  
  

  There is magic in a rain drop.  A rain drop does not wonder how, when where or why, it does not keep track of time nor wonder about how to lose weight, it just is. ~ unknown

  Purity of Rain-Water.—The water, which rises in vapor into the atmosphere from all the oceans, seas, lakes and rivers of the globe is condensed after a longer or shorter time, and falls to the earth again as rain. Rain-water, being in reality a distilled fluid, is the nearest approach to a pure water which we find in nature, and when caught in clean vessels placed upon elevated objects is almost free from contamination.

• Deadly Affect of Water Impurity
  
  

  Deadly Affect of Water Impurity.  — according to the late Dr. William Budd, it also appears to be highly probable that, the poison of typhoid fever enters the system by drinking water, infection is more certain than when it is disseminated by the hair and is breathed into the lungs.  It’s part of the statement, he instances an outbreak which occurred in Wales, where out of ninety or a hundred persons who attended a ball, fully one third was shortly afterward laid up with fever.  Although the water was not examined, there was satisfactory reason to believe it was polluted with sewage.

   

  Even in public places where you would expect the aristocracy or at least the rich people together, water impurity was such a problem that sewage could be mixed into the drinking water supply at a ball.  Clearly this highlights the fact that discovering this problem was still relatively new compared to attempt to deal with the problem effectively.  This was such a new problem, that they were literally dying from it because they could act fast enough, and maybe they didn’t even know that they were supposed to act fast.  For all we know looking at this account, replacing their Movado watches might have been of higher importance than investing money in improving their drinking water supply.
