    Of the other cases had pericarditis males 0, females 1; „ „ endocarditis only „ 3 „ 3. The cases of recent cardiac complication were, therefore, 7 in number, or 1 case in 1*5, or 66*6 per cent. Of the 10 subacute cases, 7 were males and 3 females. Of these were wholly free from signs or symptoms of cardiac affection, male 1, female 0. Had slight signs only, males 2, female 0. Eegarding the latter as healthy, the cases uncomplicated by heart affection were, therefore, 3 in number, or ]. case in 3*3, or 30 per cent. Of the remainder had peri- and endocarditis, males 1, females 1; „ „ endocarditis only „ 2 „ 2 j „ „ old cardiac disease „ 1 „ 0. The number of cases in which cardiac complications existed was therefore 7, or 1 case in 1*4, or 70 per cent. Taking both series of cases together— 4 cases were entirely free from cardiac affection ; 3 „ had only slight signs, and may be regarded as free. The number of uncomplicated cases was thus 7, or 1 case in 3, or 33*3 per cent. Of the other cases— 1 had pericarditis only; 2 „ peri- and endocarditis; 10 J, endocarditis only j and 1 old disease only. The total number in which cardiac affection occurred being thus 14, or 1 case in 1*5, or 66*6 per cent. If the case in which there was old disease be not calcu- lated, the cases of recent heart complication only are 13, or 1 case in 1*6, or 61*9 per cent. In one of the cases of peri- and endocarditis there was also old disease, the sequence of a previous attack of rheumatism of which the date was not ascertained. It is probable also that in other cases in which there was marked cardiac disease, there may have been recent rheumatic symptoms, and that these may have escaped enumeration, from the cases being reported only as cardiac. The mean age of the patients with recent cardiac complica- tion did not materially differ from that of the other patients, being in males 23*3 years, and in females 22*3. Of the cases in which recent cardiac^complication occurred, 9 are reported or may be inferred to have been recent or first attacks, and in 4 the patients had previously suffered from rheumatism.
