The writer has much reason to believe he has found a reliable pointer for the cause of croup, diphtheria, and pneumonia; also a rational and easy cure that any mother can administer and save the babe from choking to death in her arms. Having witnessed croup in all its deadly work for fifty years, and seen the best skill of each year and generation fail to save, or even give relief, I lost all hope and grew to believe there was no help and the doctor was only one more witness to the scene of death and carnage found along the mysterious road that croup travels to slay the babes of the whole earth. Of later days we have new and different names for the disease, but alas, it kills the babe just as it did before it was called diphtheria, la grippe and so on. SOME ADVICE TO MOTHERS. I write this more for the mothers than for the critics. We say to mothers, as you are not Osteopaths, you are perfectly safe in putting glycerine in a child's ears. It is made from oils and fats. I believe when the wax is not consumed it clogs up the excretories with dead matter, thus the irritation of the nerves of throat, neck, lungs and lymphatics which give cause for the swelling of the tonsils and glands of the neck. In this book can be found why I see wisdom in treating for croup from the nerve centers of the brain. So far the uses and importance of healthy ear-wax as a cure for disease has had no attention that I can find by any author on disease or physiology. I hope time and attention may lead us to a better knowledge of the cure of diphtheria, croup, scarlet fever and all diseases of the throat and lungs of children, and how to cure a greater per cent than has been up to this writing. My experience up to date with such diseases, when treated as indicated, has been very encouraging. Though it is but a short time since I began to treat by this method, it has proven good with the young and old. As all authors so far seem silent even as to how or when the wax is formed, we must resort to much careful dissection to find the relation of the cerumen system to health. To intelligently acquaint the mother with this treatment who does not understand anatomy so as to give Osteopathic treatment for croup, diphtheria, and so on, I will say; take a soft wet cloth and wash the child's neck and rub gently down from ears to breast and shoulders; keep ears wet, often dropping in the glycerine. Use glycerine because it will mix with the water and dissolve the wax, while sweet oil and other oils will not do so. A CASE IN POINT.
