The first class is characterized by comprising those causes which are for the most part accidental. They are peculiar to confinement and motherhood, and may be in a great degree controlled or averted by the skillful and competent accoucheur. They have principally a scientific interest, and do not fall within the scope of the non-professional reader. The second class is entirely beyond anyone’s control. The causes belonging to this category are innate to the human organism; they induce those numerous afflictions which here and there sprout up in previously healthy persons, and are, in all probability, due to some specific hereditary taint. They are to be attributed to the natural imperfections of humanity, and are a constant reminder that the body is simply the transient abode of the soul, or spiritual man, and as such only perfect in its imperfections. Like the causes of the first class, these, too, have principally a scientific interest. The third class of causes of uterine diseases constitutes a very large group, and has a popular or general interest. For this reason it should be freely discussed, because the causes of this class are _avoidable_. They are entirely within the control of the average sensible person, and for that reason should be known and understood by everyone. These causes superinduce inflammatory diseases, which are not confined to the womb alone but take in the entire pelvic _appendages_, the Fallopian tubes and ovaries. They are the greatest source of revenue to the doctors, and vary in symptoms in different persons, from a slight casual reminder of something wrong to harassing pains and physical suffering; and that these all are brought about through ignorance, wanton carelessness, or sinful disrespect of nature’s or God’s law, is the characteristic feature of the causes under investigation.
