More
These bottles were used for oceanographic research in the early years of the 1900s. They had two chambers with hinged lids and attached reversing thermometers, so that water temperature of two samples could be measured at different depths. They were also designed so that several bottles could be deployed on a line, with a system of messenger weights triggering the operation of bottles at different depths.
