of the Indians of Peru. While admitting the marvellous skill of the American Indians in following up their quarry, most of us will, I imagine, be inclined to doubt whether its dependence upon smell is a true inference from the facts observed. Skill in woodcraft can be brought to such marvellous perfection that it may seem like magic to the onlooker—like magic, or like scent !
Further, although we are able to distinguish clearly enough between different odours, the identification and the naming of odours does not
come easy to us. Parfumeurs and druggists, no doubt, by the daily education of the sense, attain to a high degree of skill in this art, but those who have not cultivated their powers will find it very difficult, as the amusing parlour-game of guessing the names of concealed foodstuffs and spices shows. The difficulty is, like the paucity of olfactory terms, probably due to an absence of ready communication between the olfactory and speech centres in the brain.
