There are a great many truths in surgery and medicine in which a satisfactory explanation of the manifested phenomena has never been discovered. The explanations of how tubercular peritonitis is cured by a peritoneal opening are many, but none are satisfactory; hence I trust I may be pardoned if I add another, which to me is original.
It would seem from the findings in most of these cases that there was not a local focus from which the disease spread, or if so, that focus was overshadowed by the later and more widespread process. The nodules have been about equally distributed over the peritoneum in most of my cases, both visceral and parietal. Inoculation experiments have demonstrated the extreme susceptibility of the peritoneum to tubercular invasion. This membrane can resist the inroads of most of the pus microbes better than the tubercle bacilli.
Most of my cases have been in
