Anosmic

"He had an anosmic patient who was very fond of the bouquet of moselle. […] One gentleman fell from his horse, fractured the ethmoid bone, and became anosmic."

"The whales, porpoises and seals have however a reason that man does not possess for being anosmic. For they, in common with all the living world of earth and air, left the sea millions of years ago and, as they developed lungs with which to breathe, so did they modify their organs of smell to receive sensations from air, not water. Eons later, in comparatively recent geologic times, when these few mammals left the land and returned to the water, this differentiation for air-smelling had gone too far. Their senses of smell failed to react to water-borne stimuli. […] It is worth discussing these anosmic animals, and what caused them to lose the sense of smell."

"A person who has lost the sense of smell (an anosmic) is deprived of more than pleasurable sensations, for it has been argued that as the environment becomes more polluted what the nose knows may have to be taken seriously[…]."
