Vintage patent medicine bottle. Clear glass bottle embossed with "Groves Tasteless Chill Tonic prepared by Paris Medicine Co. St. Louis." In 1878, E.W. Grove figured out how to make a relatively tasteless suspension of quinine, a very bitter drug used to treat malaria. It was sold as a preventative and treatment for the chills and fever associated with the disease. It became a household sensation, selling millions of bottles per year, reaching peak sales in the mid 1930's. Paris Medicine Company became Grove laboratories in 1934, and continued to make the Chill Tonic into the 1950's when it was absorbed by Bristol Myers Company (1957). This bottle is in "as found" condition. It measures 5 3/4" tall by 2 1/2" wide by 1 1/2" thick, and originally would have had a cork closure. This bottle probably comes from the 1930's (it is marked with a "J" in a diamond on the the bottom). It is in very good to excellent condition, with no chips or cracks.
