Vintage apothecary bottle from the 1920's to the 1940's. Contained Tannis Chinini (quinine tannate, an extract of Chinona bark) . This form of quinine is less bitter than quinine sulfate, and was widely used to treat whooping cough and malaria in children. The amber bottle helps protect the compound, which is light sensitive. This bottle, which most likely came from Eastern Europe, has a black and white decal label (no cover glass was used). The bottle measures about 5" tall by 2" diameter. It has a very unusual ground glass stopper with a hollow dome and stem that is filled with a dry powder. The open end of the stopper is sealed with a piece of cloth tied around the stopper. I believe that this stopper contains a moisture absorbent to help protect the contents from moisture in the air. Overall, the bottle is in very good condition.
