At the sugyi-stiou of Professor Tate, to wliose work I aiu already much indeljteil, 

 I have added to tlie narrative tlie following short sunnnary of the results of the 

 Expedition so far as they are concerned with Zoology, Uotany and Geology. I 

 have not included in the summary the Anthiopological work for the simple rea.son 

 tliat a mere biic^f outline of tlie work of Dr. Stirling and Mr. Gillen would have 

 been of no value, whereas, in the case of the three sciences mentioned tlie connec- 

 tion between them is so intimate and the bearing, especially of the Geological 

 work, upon the important question of the distribution of the fauna and tlc»ra is of 

 such a nature that it appeared to be of advantage to bring together and briefly 

 discuss the main results ari'ived at in these departments. For the Geological and 

 Botanical results I am of course indebted to the papers written 1)y Professor Tate 

 and Mr. Watt, singly and in conjunction with each other. Un one or two points, 

 such as for examjile the previous existt^nce of a " cosnjopolilan llora " in Australia, 

 I have ventured, when discussing certain general conclusions, to diil'er from the 

 views put forth in the reports. 



ZOOLOGY. 



In the narrative some of the more interesting points in regaitl to dilierent 

 forms of animals found have been already alluded to. 1 shall here endeavour to 

 brietly summarise the general results.
