This collection contains a single preliminary sketch, labelled “Le tarsier podje [tarsie Duett?] vol 13 des Iles moluques,” done by Jean Baptiste Audebert for his book Histoire naturelle des singes et des makis (1800). The final illustration appears in the book identified as “Le Tarsier / Tarsius Daubentonii.” This sketch was executed largely in watercolor with some body color and ink details.
