Ability To Smell
The horse's olfactory receptors are located in the mucosa of the upper nasal cavity. Due to the length of the nasal cavity, there is a large area of these receptors, and the horse has a better ability to smell than a human. Additionally, the horse also has a vomeronasal organ, or Jacobson's Organ, which is in the hard palate, and is able to pick up pheromones and other scents when a horse exhibits the flehmen response. The flehmen response forces air through slits in the nasal cavity and into the vomeronasal organ. Unlike many other animals, the horse's Jacobson's Organ doesn't open into the oral cavity.

“The only fruit which even much living yields seems to be often only some trivial success,—the ability to do some slight thing better. We make conquest only of husks and shells for the most part,—at least apparently,—but sometimes these are cinnamon and spices, you know.”
—Henry David Thoreau (1817–1862)
“The truth is, no matter how trying they become, babies two and under don’t have the ability to make moral choices, so they can’t be “bad.” That category only exists in the adult mind.”
—Anne Cassidy (20th century)
“You never saw this room before a show,
Full of lank, shivery, half-drowned birds
In separate coops, having their plumage done.
The smell of the wet feathers in the heat!”
—Robert Frost (1874–1963)
