Standard large-capacity Admiralty water-bottle for collecting water samples for analysis, as used on HMS Porcupine, c.1869.

The cruises of HMS Porcupine were initiated by the Royal Society with the cooperation of the Admiralty and followed a cruise the previous year by HMS Lightning. They carried out dredging operations to investigate sea bottom temperatures and the organisms in the deep sea. The scientists aboard Porcupine also carried out chemical analyses of seawater samples, which were collected with bottles like these.

The brass tube was fitted with conical valves. The inside would have been coated with sealing-wax to prevent corrosion and contamination of the sample.
