Boiling liberates the tannic acid of the tea, which acts upon the tin, making a compound bitter and metallic in taste, and unfit for human stomachs.
COFFEE.
The best coffee is made from a mixture of two-thirds Java and one-third Mocha; the Java giving strength, and the Mocha flavor and aroma.

The roasting must be very perfectly done.

If done at home, constant stirring is necessary to prevent burning; but all good grocers use now rotary roasters, which brown each grain perfectly.

Buy in small quantities _unground_; keep closely covered; and if the highest flavor is wanted, heat hot before grinding.
A noted German chemist claims to have discovered an effectual antidote to the harmful effects of coffee,--an antidote for which he had searched for years.

In his experiments he discovered that the fibre of cotton, in its natural state before bleaching, neutralizes the harmful principle of the caffein.
