It is well known that some savage tribes with their large, open nostrils not only recognize their enemies but also track game the same as hounds.
Individual Odors .-- Many individuals are said to have exhaled particularly strong odors, and history is full of such instances.

We are told by Plutarch that Alexander the Great exhaled an odor similar to that of violet flowers, and his undergarments always smelled of this natural perfume.

It is said that Cujas offered a particular analogy to this.

On the contrary, there are certain persons spoken of who exhaled a sulphurous odor.

Martial said that Thais was an example of the class of people whose odor was insupportable.
