The Admiralty instructions for the first voyage had required officers "to use their best diligence in increasing the Collections in each ship: the whole of which must be understood to belong to the Public", but on the second voyage this requirement was omitted, and the officers were free to keep all the specimens for themselves.
As instrucións do Almirantado para a primeira viaxe esixían aos oficiais "usar a máxima dilixencia en incrementar as colección de cada barco: a totalidade das cales debe entenderse que pertencen ao Público", mais na segunda viaxe esta esixencia foi omitida, e os oficiais eran libres de quedarse para eles todos os espécimes.
