139 pencil drawings and watercolour paintings produced by Westall, all but 2 from the voyage of HMS Investigator (1801-03).  Capturing landscapes, coastal profiles, and Indigenous peoples, these works offer a vivid, accurate record of early Australian encounters. As one of the first professional artists to visit Australia, Westall’s collection is a significant historical and cultural treasure.

About 600 books and 66 serials, mainly relating to entomology and the natural sciences. Includes works on British entomology as well as Europe, North and South America. About one-third were published in the 18th and 19th centuries.
