In the Philadelphia Medical Journal of Nov. 12, 1898, Dr. Flexner of Baltimore presents certain facts obtained by the postmortem study of a large number of cases of peritonitis in which careful bacteriologic examinations were made.
Among the earlier studies of the experimental peritonitis, that of Grawitz in particular, as well as of others, has clearly defined the conditions that result in the development of peritonitis in animals. Grawitz has also shown that these results are nearly allied to the natural conditions found in man.
