46 Mr. Brown, on the Proteacea of Jussieu. 



by that of Sir Joseph Banks, has, with his accustomed liberality, 

 submitted it without reserve to my examination. 



Mr. Ilibbert, who for many years possessed the most extensive 

 collection of living Proteas that has ever been formed, and 

 who also received from his intelligent collector Mr. Niven a va- 

 luable Herbarium of native specimens, most obligingly permitted 

 me to examine these, and even to dissect such as were new. For 

 the like privilege I am indebted to the friendship of Mr. Aiton 

 of Kew, who sent me his whole collection, peculiarly valuable 

 as gontaining many of the original specimens of Mr. Masson : 

 and lastly, I have to acknowledge the great assistance I have 

 derived from the extensive collection presented to this Society 

 by my friend Dr. Roxburgh, \vho during his short residence at 

 the Cape appears to have paid particular attention to this tribe 

 of plants, and who, besides the many new species discovered by 

 him, has given a greater value to his Herbarium by numerous 

 observations on the sexes, the size, and places of growth, which 

 I have every where inserted on his authority.
