History and etymology
In the days when snuff use was popular, the user would place a small amount of snuff from the container into the "anatomical" snuff box (as opposed to the physical snuff box which he carried around in his pocket, hence "anatomical" ), close one nostril with an index finger and sniff the snuff up the open nostril. It was common practice to offer snuff to those in your company.
