ON THE NORTH-AUSTEALIAN EXPEDITION.

prosecution of my labours, which I found facilitated to the fullest 

 extent, as far as circumstances would permit. 



I have also to acknowledge contributions towards the botanical 

 collections from all the officers of the expedition, and although 

 those additions yielded but a very small number of species not 

 observed by myself, yet I was thus enabled to reexamine many 

 plants in a more perfect state of development. 



I am placed under the greatest obligation to Mr. Walter Hill, 

 Curator of the Brisbane Botanic Grarden, not only for commu- 

 nicating some valuable and unique specimens, but also for his 

 disinterestedness in assisting me with his local knowledge of the 

 Moreton Bay district, in obtaining many botanical rarities which 

 I otherwise should have failed to procure ; and it remains for me 

 to express likewise my thanks to Mr. C. Moore, Director of the 

 Botanic Garden at Sydney, for providing me with ample room for 

 arranging the herbarium, for giving me unlimited access both to 

 the library and the collections of his establishment, and for ren- 

 dering numerous services to alleviate my labours in Sydney. 



To his Excellency the Grovernor- General I owe the deepest 

 gratitude for entrusting to me the phytological investigation of 

 such an ample and interesting tract of country, a favour, which I 

 can — ^reflecting on the rarity of such occasions for research — 

 never sufficiently acknowledge ; and finally, I feel proud to state, 

 that, through the usual liberality of Sir William Hooker, I am 

 permitted by Her Majesty's Government to retain a set of bo- 

 tanical specimens, in order to elucidate hereafter to the fullest 

 extent the flora of tropical Australia. 



I have the honour to be. Sir, 

 Your most obedient and humble servant, 

 Feedinand Mullee, 

 Botanist to the North -Australian Expedition.
