i found this bottle in a channel that leads into the town of Chester CT, the channel was used to bring in big ships to unload elephant tusks for Piano Works factory in the town of Deep River and to drop off good for the surrounding areas....im not to sure what this bottle is or what it was used for.......

Yours seems more like a seltzer type medicine. Need the poison experts to weigh in.
