The following experience from the pen of Dr. H. T. Turner, of Washington, affords incontestable proof of the allegation made, that the colon is the seat of disease, and his testimony should be read with extreme care. It is no fanciful, theoretical statement, but the ghastly revelation of an appalling reality. While reading his statement, the reader will do well to refer to the engraving, representing the digestive apparatus, at the commencement of this book, as it will greatly facilitate his comprehension of the matter. "In 1880 I lost a patient with inflammation of the bowels, and requested of the friends the privilege of holding a post-mortem examination, as I was satisfied that there was some foreign substance in or near the Ileo-coecal valve, or in that apparently useless appendage, the Appendicula Vermiformis. (See explanation of engraving.) "The autopsy developed a quantity of grape seed and popcorn, filling the lower enlarged pouch of the colon and the opening into the Appendicula Vermiformis. This, from the mortified and blackened condition of the colon alone, indicated that my diagnosis was correct. I opened the colon throughout its entire length of five feet, and found it filled with faecal matter encrusted on its walls and into the folds of the colon, in many places dry and hard as slate, and so completely obstructing the passage of the bowels as to throw him into violent colic (as his friends stated), sometimes as often as twice a month, for years, and that powerful doses of physic was his only relief; that all the doctors had agreed that it was bilious colic. I observed that this crusted matter was evidently of long standing, the result of years of accumulation, and although the remote cause, not the immediate cause of his death. The sigmoid-flexure (see engraving), or bend in the colon on the left side, was especially full, and distended to double its natural size, filling the gut uniformly, with a small hole the size of one's little finger through the center, through which the recent faecal matter passed. In the lower part of the sigmoid-flexure, just before descending to form the rectum, and in the left hand upper corner of the colon as it turns toward the right, were pockets eaten out of the hardened faecal matter, in which were eggs of worms and quite a quantity of maggots, which had eaten into the sensitive mucous membrane, causing serious inflammation of the colon and its adjacent parts, and as recent investigation has established as a fact, were the cause of his hemorrhoids, or piles, which I learned were of years' standing. The whole length of the colon was in a state of chronic inflammation; still this man considered himself well and healthy until the unfortunate eating of the grape seed and popcorn, and had no trouble in getting his life insured in one of the best companies in America.
