When Hewitt introduced his regulating stopcock in 1887, attempts were made to dilute the nitrous oxide with air and so obviate the element of asphyxiation. The method was to be seen in London, mainly in dentistry and minor surgery, so late as 1930. It was not very successful. To give even 10% of oxygen (which is not enough) the gas-mixture must contain 55% of air and 45% of nitrous oxide. The latter is thus so diluted by atmospheric nitrogen as to be incapable of producing anaesthesia except by asphyxiation. "Gas-air" was confined to analgesia, for example in midwifery.

Sir Frederic W. Hewitt (1857-1916), an accomplished and well respected English anesthesiologist, was an expert in the function and use of the Clover Ether Inhaler. In 1901, Hewitt described his modification of the Clover Inhaler. Often referred to as the Hewitt Wide-Bore Inhaler, Dr. Hewitt introduced changes in order to make it easier to breathe through the device and improve the ventilation of oxygen and carbon dioxide. In 1901, Hewitt was recruited to anesthetize King Edward VII for emergency abdominal surgery. This was just a day or so before the new King was to be coronated. He recovered well, and Hewitt became the first anesthesiologist ever to be knighted. (Source: Wood Library Museum)Tall black round topped box with brass hooks at the sides and brass hinges at rear.

Lambert Ormsby was a New Zealand surgeon who migrated to Ireland. He described his inhaler in a letter to the Lancet in 1877.Ormsby listed the advantages of his inhaler as simple, inexpensive, small quantity required to produce sleep, prevents evaporation of ether, portable and small (can be carried in pocket), short time to complete anaesthesia (two minutes) and safe. Disadvantages of this apparatus were that it had to be removed in order to recharge the sponge with ether or when anaesthesia becomes too deep. Considerable carbon dioxide accumulation developed and there would also be some oxygen lack. In thirty years of use, Ormsby's Inhaler underwent certain modifications, an exhalation valve was fitted to the mask and device for recharging the sponge with ether was later added. The Ormsby inhaler was modified by Carter Braine in 1898 with the aim of making it easier to clean. Essentially it is very similar except there is no net around the bag.The inhaler consists of an india-rubber flexible bag enclosed within a net bag to limit expansion. There is a soft metallic mouthpiece with india-rubber tubing around the edge. The tubing had to be purchased separately from the manufacturer. The body contains a wire cage with a similarly shaped hollow sponge into which ether was poured.Maker's details inscribed into metal ring around the bore: Barth Co.
