I have had an opportunity to observe the influence of vaccination upon a case of whooping cough. The patient was vaccinated the same as is done for the prevention of smallpox. When the ulceration on the arm was healed, the cough had disappeared. I cannot explain the action of this treatment but I am satisfied that it will prove satisfactory.
In the treatment of membranous croup, I use the second or third trituration of kali bichromatum. One-half grain of this powder is blown into the throat in a careful manner during an inspiration. I have observed relief from its use within less than one minute.
In its later influence it disorganizes the membranes. I use a tube five or six inches long, and since I have adopted this treatment I have had the most excellent results. In fact, I think I have not failed in a single case since I learned how to administer it properly.
