1. Partially exhausted and refired tea-leaves, known as “Ching Suey” (clear water), which name doubtless has reference to the weakness of a beverage prepared from this article.

2. “Lie tea,” made from Wampan leaves.

3. A mixture of 10 per cent. green tea and 90 per cent. “lie tea.” It is sometimes sold as “Imperial” or “Gunpowder” tea, and is stated to be extensively consumed in France and Spain.

4. “Scented caper tea,” consisting of tea-dust made up into little shot-like pellets by means of “Congou paste” (i. e. boiled rice), and said to be chiefly used in the English coal-mining districts.

The following are the results of the analysis by American chemists of samples representing 2414 packages of Indian tea.
