While cases of meningococcic septicemia are common, being reported in large series in the literature, those in which accompanying endocarditis and myocarditis have been proved are uncommon. The literature at the present time contains 17 case reports of endocarditis and 12 of myocarditis caused by the meningococcus. Cardiac involvement of these types has proved rapidly fatal in the majority of cases, while in a smaller number the course has been subacute or chronic. Cases have been reported more frequently during the past ten years, as up to 1927 there were only 11 cases in the literature (Rhoads1). The duration of the disease varies from ten days (my case) to eight and one-half months (Gwyn2), the average being about six weeks.
An early diagnosis of meningococcic septicemia, with its various lesions, is often not arrived at, owing to the resemblance of the symptoms to those of other, more frequent, conditions. The
