The common fly (Musca domestica).- the only way to prevent the flight curing diseases to destroy history in place, keep them out of the home, etc., when developed, by screens and swat or catch by flypaper, etc., everyone seen in a room.

Houseflies are a danger to human life.  Airborne filth, feed upon garbage, sewage waste matter of all kinds.  They carry germs on the pro-business of their bodies, and a single flaw is known to have carried as many as 350,000 germs and given them off into the liquid food in which it was floating.  They also carry numerous germs inside their bodies which they convey to food, etc., and their vomit and all matter.

Flies can carry disease germs of typhoid fever, consumption, diarrhea, dysentery and other diseases from a sufferer to you.  They come in contact with your food, milk, water, etc., you're sleeping child, or a light on an open wound, direct from the garbage can, because the door, this bit industry, etc., from decaying animal and vegetable matter and from the sick room.  Thus every individual should do everything possible to aid the physician, city and state and destroy these known carriers of filth and disease and thereby prevent sickness, due to carelessness and indifference by permitting flies to breathe and live.

If you consider the tone of this particular section, you would think that the housefly was the Swiss Army knife of disease carriers in the Western world.  In fact today we understand their purpose and the world a little bit better, but that doesn't mean that they should be entirely permitted to run amok.  Typically the presence as a result of some other item that has started to decay in the area and attracted flies.  The presence of this item sometimes can be more dangerous than the flight itself, but the fly can definitely spread that around once the process is started.  In their defense there are some practical uses for utilizing flies or even sterile I'll maggots to help clean items from time to time.

• Pleura of the Lungs – Size/ shape/ weight of lungs
  
  

  Pleura of the Lungs. –in this chart we see also the pleura or the investing membrane of the lungs, and right below it the diaphragm or midriff.Two Distinct Lungs. –although the lungs are two in number, as far as their structure is concerned, and are perfectly distinct from each other, having, as we observe in the chart underneath this one, the heart and blood-vessels between them, yet as regards their functions they may be considered the same, since they received their blood from a single vessel, the pulmonary artery, and the air by one canal, the trachea or wind-pipe, and act in common with each other.

  Size and Shape of Lungs. –as will be observed, the lungs are not quite the same size or shape; the right lung, although somewhat shorter and thicker than the left, is the larger and stronger, being divided into three lobe; wills to the left is the smaller and weaker, divided into two lobes only, and hence more frequently subject to disease.

  Weight And Shape of Lungs. –the weight of the lungs varies very much; but in general they average about forty-two ounces in the male;thirty-six in the female; the right lung been about 2 ounces heavier than the left. Each lung is comical in shape, with a broad concave base resting on the convex surface of the midriff, the apex directed upward and extending into the root of the neck about 1 inch above the level of the first rib.

  ______________
  This section sounds much more scientific than the opening statement, it does have quite a few excessive examples of commas and even a few semicolons, but it doesn’t mention corsets, and it seems to stick to the facts or leased a description of the lungs in this particular case.

  A student studying medicine might learn something about the lungs from the section, although I suppose it probably was a practical thing to learn hundred years ago that corsets cause and strictures in the lungs. In fact it might have even been common knowledge although there may have been some sort of taboo against discussing such things and maybe it was only known by certain people. Therefore it might’ve been very practical to call that a medical book in case male readers or male doctors were somehow ignorant of the problems caused by corsets.

• How is Malaria carried by the Mosquito
  
  

  How is malaria carried by the mosquito?-best imagined that a man has returned from some malarial country takes up his abode in a healthy, yet mosquito infested village.  This man may be fairly over his attack yet he still suffers from an occasional chill with fever.  He has no screens in his house, nor have his neighbors, unless previously told to follow such cautions.  A female as Cato are several attack in and stuck his blood which contains these tiny parasites.  The mosquito takes millions of the little parasites which then undergo a development in the body of the insect and can be seen microscopically in the stomach and intestine, and the small glands in its mouth, which secrete saliva.  Now let us follow the mosquito and see what harm it can cause any community.  It flies through a screen door or window and lights on the arm, etc., of an unsuspecting neighbor.  Inviting a person the mosquito ejects or gives off its saliva into the womb to eight in diluting the blood of a person which it has been, as the blood is too thick to be sucked up to the tiny tube in the bill (proboscis) of the mosquito.  In this way the bite of the female mosquito whose body contains a small animal error sites which cause malaria, as by means of the saliva into the blood of the person during the act of sucking up the blood.  Does the mosquito sucks up the blood of the individual and in exchange injects into his blood the saliva contains parasites.  These parasites multiply in the blood of the person bitten and produce poisons which give rise to the chills, fever, aching limbs, etc., known as malaria, malarial fever or “odd,” (chills and fever).  It can readily be seen how malaria will spread when individuals in the community have millions of parasites in the blood, and at the same time as Cato’s are carrying around in their bodies, millions of the same living germs which they sought from the blood of the infected person, develop and inject them into the blood of every person they bite.

  You will notice as you read the follow on sections covering Mosquitos and Malaria that the book is big on talking about where they live, but not terribly practical on how to actually deal with the insects.  There are more references to different possible breeding places than there are gears in a Patek Gondolo watch.

• BONES OF THE HEAD, BASE AND NECK.
  
  

  
  

  Bones of the Skull — this illustration gives an accurate and faithful representation of the head, face and neck, surrounded by an outline of the fleshy parts as they appear in the human frame. The bones of the head, eight in number, constitute the skull, and those of the face, 14 and number, compose a strong, hard bony case, which encloses and affords a suitable protection for the brain and the four organs a special sense, viz.: site, smell, taste and hearing. All of these bones are in movable, except the lower jaw, which moves by means of a hinge-joint, and permits of the opening and closing of the mouth.

  One of the things that struck me as I dictated this last segment (for my readers information I am using Dragon Naturally Speaking to dictate this text as well as my views on the text) was the large number of commas as used in this paragraph. By my count there were 15 used in this paragraph which had three sentences. Now this book in general uses the coma extensively and reminds me of a style of writing that I was taught in grade school shortly before several rules of language were simplified. For example when I was in grade school I was taught that a conjunction that included the word “and” should have a coma in between each item building up to the conjunction including the last word that preceded the word “and.”

  Back then I would’ve drafted this sentence as follows:
  I went to the store, the post office, the car wash, and the bank.

  Later in high school some economy of writing came about and decreased 1 of the commas needed in writing. I don’t know when or why this occurred, but I do recall several grammar teachers remarking on the fact and teach in is the new writing style. Back then I didn’t follow the news quite to the extent that I do today and so I do not recall whether there was a boost in the global economy due to the increased productivity allowed workers especially “knowledge workers” who would not have had to write, type or dictate quite as many commas. In fact they would have one less coma to write. Can you imagine what everyone did with all that extra time saved him from writing?

  Now honestly one coma probably to make that big of a difference. But now as I read the library of health I realize that over the last 82 a hundred years the world hasn’t saved just one coma; they have saved close to a dozen per paragraph. Computers may have brought a significant amount of productivity to the workforce, but just imagine how much we’ve saved over the last hundred years writing fewer comas.

  I wonder when the majority of the comas as were lost. Maybe it was the result of World War I or World War II or the combination of both wars. It’s possible that to expedite communications Society had to adapt and reduce the number of dits in das used in a telegraph. The war to end all wars may have failed in Indian all wars, but it may have succeeded in putting an end to a few extra comas.
