title: Practical test kits for quantitatively evaluating the sense of smell.
abstract: A set of polypropylene squeeze-bottles, containing serial dilutions of pyridine in mineral oil, are used to deliver puffs of accurately odorized air to the nose. The patient's olfactory threshold can be quantitatively measured in a few minutes, and placed in the normal, hyposmic or hyperosmic range of sensitivity.
