A rare early 20th Century
Bennett's portable anaesthetic inhaler. The central body of the
inhaler is filled with an absorbent cotton into which the ether or
anaesthetic agent would be poured. The screw on cap would then be
replaced. The agent was then administered to the patient by holding
the nasal prongs (the tips of which are made from some form of gutta
percha) to the nares. Later versions were made from all metal.
