You cannot do otherwise, and not betray your ignorance to the thinking world. If in the human body you can find the most wonderful chemical laboratory mind can conceive of, why not give more of your time to that subject, that you may obtain a better understanding of its workings? Can you afford to treat your patients without such qualification? Is it not ignorance of the workings of this Divine law that has given birth to the foundationless nightmare that now prevails to such an alarming extent all over civilization, that a deadly drug will prove its efficacy in warding off disease in a better way than has been prescribed by the intelligent God, who has formulated and combined life, mind and matter in such a manner that it becomes the connecting link between a world of mind, and that element known as matter? Can a deep philosopher do otherwise than conclude that nature has placed in man all the qualities for his comfort and longevity? Or will he drink that which is deadly, and cast his vote for the crucifixion of knowledge? CHAPTER XVI. REASONING TESTS. The Vermiform Appendix--Operating for Appendicitis--Expelling Power of the Vermiform Appendix--Care Exercised in Making Assertions--Reasoning Tests--A List of Unexplained Diseases--Concluding Remarks. THE VERMIFORM APPENDIX. At the present time more than at any other period since the birth of Christ, the medical and surgical world have centralized their minds for the purpose of relieving locally inside, below the kidney of the male or female, excruciating pain, which appears in both sexes in the region above described. From some cause, possibly justifiable, it has been decided to open the human body and explore the region just below the right kidney in search of the cause of this trouble. Such explorations have been made upon the dead first. Small seeds and other substances have been found in the vermiform appendix, which is a hollow tube over an inch in length. These discoveries, as found in the dead subject, have led to explorations in the same location in the living. In some of the cases, though very few, seeds and other substances have been found in the vermiform appendix, supposed to be the cause of local or general inflammation of the appendix. Some have been successfully removed, and permanent relief followed the operation. These explorations and successes in finding substances in the vermiform appendix, their removal, and successful recovery in some cases, have led to what may properly be termed a hasty system of diagnosis, and it has become very prevalent, and resorted to by the physicians of many schools, under the impression that the vermiform appendix is of no known use, and that the human being is just as well off without it.
