Murray. During this year he made a more extended exploration 
of the Australian Alps, as detailed in his Second General Report 
dated October 1854. His other explorations were under the 
leadership of A. C. Gregory in 1856 to explore North-western 
and Northern Australia for traces of Leichhardt, journeying from 
the Victorian River overland to the Dawson, and botanical 
expeditions of an exploratory character to Western Australia in 
1867 and 1877 respectively, the former trip being from King 
George’s Sound to the Stirling Range, and the latter to the Shark’s 
Bay district. 
The mere recounting of the Baron’s works would take up more 
time than can be allowed on the present occasion, but I may

an invaluable supplement to the Flora, while the Systematic 
Census of Australian Plants, of which two editions have appeared, 
is indispensable to the student, being a cyclopeedia of notes on

It is one of a series of valuable quartos dealing with various

“ Eucalyptographia” in the absence of descriptive accounts of 
each plant), are the “lconography of Acacias and Cognate Genera,” 
*‘Tconography of Australian Salsolaceous Plants,” ‘‘ Descriptions 
and Illustrations of the Myoporinous Plants of Australia,” and 
“Tconography of Candolleaceous Plants” (only one decade issued). 
The “Plants indigenous to Victoria,” in two folio volumes, with
