In our paper " The Use of Parica, an Ethnological and Pharmacological Review", Professor Bo Holmstedt, M. D ., as a pharmacologist and I myself as an anthropologist specialized in the study of American Indians, have touched on the difficulties in classifying, medically satisfactorily, vague expressions as regards the descriptions of the symptoms of a snuff taken by the Indians for specific purposes (Wassen and Holmstedt: 1963, p. 35-36). If we turn to the old written sources this difficulty becomes still more accentuated. To exemplify this I first want to refer to the discussion of the cohoba powder used as a snuff by the natives of Espanola or Haiti at the time of the arrival of the Whites and first mentioned by name in the small but invaluable treatise by Friar Ramon Pane. A more complete treatment of narcotic drugs and related paraphernalia used by the South American Indians will be presented on a later specific occasion from a manuscript which already has been prepared.
