Attention has been recently called in several quarters to the simulation of appendicitis or peritonitis by pulmonary processes, especially pneumonia and pleurisy. The fact that this simulation often occurred has long been known, but is commonly overlooked, and, inasmuch as the diagnosis is certainly at times extremely difficult, and since operation for appendicitis has even been performed when only pneumonia was present, I have thought it of interest to report a few cases of this nature and to quote those of like sort which have come to my notice in medical literature, limiting myself entirely, at least in detailing cases, to the occurrence of the condition in early life. It is, indeed, at this time that the confusion is most likely to happen, although some cases developing later in life are also met in literature.
Of the cases reported here the first two have already been
