1. A small number of English translations from other languages has been included (see especially Stanislaw Pietkiewicz, "The evolution of the map definition during the last hundred years," Actes du xie Congres International d'Histoire des Sciences, Varsovie-Cracovie, 1965/4 (Wroclaw, 1968), pp. 272-5) but none of these translations is the work of the present author.
2. The full texts of the definitions are obtainable from the author at the Department of Geography, Trinity College, Dublin, Ireland, or on the World Wide Web at http://www.usm.maine.edu/~maps/essays
3. The word "recorded" here and throughout this paper refers only to the author's sample. This means that not more than limited significance can be attached to the dates of so-called first and last occurrence. Some of these dates are in any case approximate.
4. The figure for planar representation may be supplemented by another 18 definitions (1775-1989) that specify paper as the commonest cartographic medium.
5. It seems clear from the context that "projection" in these cases does not carry the specialized mathematical meaning familiar in modern cartography.
