- adj. Having a good sense of smell
from The Century Dictionary and Cyclopedia
- Having the organs of smell, especially the ethmoturbinals, well developed: contrasted with microsmatic. According to Turner, the application of this and related terms depends largely upon the number of ethmoturbinals, live being characteristic of most osmatic animals, anosmatic animals having four or less, and macrosmatic animals from six to eight.
Sorry, no etymologies found.
But all the parts of the rhinencephalon, which are so distinct in macrosmatic mammals, can also be recognized in the human brain.
