6. Ihid, page 193, we have a letter dated from the Sydney Botanic 

 Gardens, March 6th, 1857. 



A chatty letter on botanical matters, referring in part to the 

 vegetation of the Northern Territory. Certain natural orders are 

 discussed seriatim. 



7. Ihid, page 225, Mueller continues his discussion of certain natural 

 orders.

Descriptions in Latin of certain new genera, not all from the 

 Northern Territory.

Then we come to Landsborough's Expedition of 1861-2. 



Henne. — Diedrich Henne, who was born at Hanover, Germany, 

 in 1834, was the botanical collector of Landsborough's expedition in 

 search of Burke and Wills. He is the last survivor of the expedition, 

 and lives in Sydney. 



The following two works may be referred to : — 



Landsborough (Wilham) — " Journal of Landsborough's Expedi- 

 tion from Carpentaria in search of Burke and Wills." With a map 

 showing the route. 8vo., pp. 128 ; Melbourne, 1862. At page 8, refers 

 to " Mr. Hennie (Henne) the botanist." There are very few botanical 

 notes. A few are given at page 115. 



" Landsborough's Exploration of Australia from Carpentaria to 

 Melbourne, with especial reference to the settlement of available 

 coujitry." Edited by James Stuart Laurie, formerly H.M. Inspector 

 of Schools. With a chart and a systematic arrangement of Carpen- 

 tarian plants, by F. Mueller, Ph. D.l &c., 12mo., Lond., 1867. 



The title of Mueller's contribution is " Plants noticed around the 

 Gulf of Carpentaria, from the Roper to the Gilbert River, including 

 those collected during Mr. Landsborough's Expedition." (n). 



(m) A succinct account of the North Australian (A. C. Gregory) Expedition will 



be found in " An Historical Review of the Explorations of Australia." Mueller 



(Trans. Phil. Inst. Vic, Vol. II., pp. 160-.3). 

 (n) Compare also " A Systematic Arrangement of the Plants Noticed Around the 



Gulf of Carpentaria from the Roper to the Gilbert River " (Mueller, 



Melbourne, 1862), which I have not seen.
