This edition, published in London [i.e. Berlin], differs from another 1771 edition, published in London [i.e. Berlin] (v.1-2) and Berlin (v.3), by the following features: Its format is 12mo; the contribution by Pernety forms part of v.3 and does not have a title page of its own; v.1 and 3 have half title pages; and, due to a larger typography, the number of pages in each volume is higher.
"Défense des Recherches philosophiques sur les Américains" is a reply to "Dissertation sur l'Amérique & les Américains" and follows it without a break in pagination.
In this edition, the title vignette on each title page is a single flower.
