long, curved, shortly tomentose (at least when young). W. and A. 

 Bark like that of A. ferruginea in its properties. 



*#* Besides these several New Holland Acacias yield a substance simi- 

 lar to Catechu, especially 566. A. mollisima, 566 a. A. decurrens, and 

 566 b. A. melanoxylun. The extract of this bark has been exported 

 in considerable quantity under the name of extract of " Mimosa bark" 

 from Van Diemen's Land. 



I find in a recent work on that Island, that in consequence of the 

 bark having been boiled in iron vessels in the process of manufacturing 

 the extract, the latter although of great strength did not answer in 

 England, as it was found to impart a colour to the leather, which it also 

 rendered brittle. This was in the year 1828. 'Accordingly in the fol- 

 lowing years 1829, 30 and 31, bark alone was shipped at Hobart Town 

 for England, in quantities as follows : viz.
