Burrough’s Wellcome vaporole inhaler is pictured here together with a textbook image of an ammonium chloride pipe inhaler.
To use an ammonium chloride inhaler the acid and alkali constituents had first to be mixed. The inhaler resembles a chemistry experiment with its test tubes.
The drawing is from the Family Physician 1899. The Vaporole inhaler is listed in Wellcome’s price list of 1937-38.
