chances of recovery.
Now, two broad facts emerge from this study. The first is that 49 out of 144, or 1 out of 3, died in or

Now, after
examining all the evidence directly proving a structural change in the wall of the heart which was at my disposal, I found that it was not possible to use any simple clinical criterion of gross cardiac damage save one?the presence or absence of a pericardial rub. Here again, therefore, I divided my cases into two groups, those in which friction was heard and those in which it was not. The prognosis in these two groups I express
