THE EFFECT OF SALVARSAN UPON THE HEART IN DOGS.
The intravenous infusion of 0.5 per cent. acid "606" causes a weakening of the heart which is usually fatal. The intravenous infusion of 0.5 per cent. alkaline "606" causes no marked apparent effect upon the heart, but its factors of safety may be so reduced in some instances that a slight extra strain produces fibrillation and death.
