![milion is six parts of mercury to one of sulphur, and forms thirty-six per cent, of the whole mass of rubber The tendency to flower, or appear in minute globules, may, by the globules being liberated by friction on the palate, and the decomposing action of light, free a small quantity of mercury, which being introduced into the stomach in a finely divided state might be acted upon by the acids there present, and the active chlorides of the metal produced. Some varieties are adulterated with arsenic, &c., to which the deleterious effects may be due. In such cases, however, it should be ascertained whether mercury has not recently been taken. It may, indeed, stay a long time in the system, and then suddenly manifest itself after taking, for example, the iodide of potas- sium.
