An unusual chloroform inhaler discovered in Cambridge was identified as James Townley's 1862 device, not a Robinson modification. This finding clarifies the provenance of historical anesthesia apparatus.

Area of Science:

Medical History
Anesthesiology
Medical Device History

Background:

An unusual chloroform inhaler was discovered during cataloguing at Addenbrooke's Hospital, Cambridge.
Initial assessment suggested it was a modification of Snow's inhaler by James Robinson.
The device was found with historical instruments from a Cambridgeshire general practice.

Discussion:

Research involved examining historical texts, medical journals, and instrument catalogues to confirm the inhaler's identity.
James Robinson's modification of Snow's ether face-piece for chloroform administration (post-1847) lacked the distinctive air-inlet tubes and funnel.
The discovered inhaler's features matched James Townley's design, introduced in 1862 for his 'Anodyne mixture.'

Key Insights:

The Addenbrooke's collection contains James Townley's chloroform inhaler, not a Robinson modification.

Further investigation into the use of Townley's inhaler in the Cambridgeshire area by practitioners like Dr. Newton and his son.
Preservation and study of historical anesthesia devices to understand the evolution of anesthetic practices.
Highlighting the importance of meticulous cataloguing and provenance research for medical artifacts.
