'Why you catch sore throats and how to cure and prevent it'. Germs from a public telephone in constant use, and railway carriages are favourite breeding grounds. An experiment on two glass plates were covered with a substance on which germs thrive, one plate being also treated with Formamint. The plate without Formamint showed an abundant growth of disease germs. You can prevent sore throats by sucking Formamint tablets. This has been proved beyond doubt - not alone by scientific tests.
