Hey Folks, After church today, while waiting for brunch, my wife and I strolled down the street to an antique store and found these two items. The demijohn is about 2 gallons in volume, 18 inches tall and about 9 in diameter. The other, I thought was a canning jar with an iron clamp BUT when I looked closer at it, there are two "eyes" in the lid where something hung off the lid and was suspended in the jar. The jar is pressed glass, no mold lines and a finely ground surface on the top. The glass is maybe a quarter of an inch thick. Now I'm thinking some kind of scientific ware. There is a patent date of June 11, 1895 on the glass lid and the screw mechanism, but no company name. Any guesses as to what it is? Scott
