SCIENTIFIC EXCURSIONS IN NEW HOLLAND. 291: 
There are many geological specimens, which I send to Dr. 
Nicholson of Newcastle. 
My herbarium is extensive, and contains a number of 
things which I do not know, and which I hope to study when 
I return from Port Essington. The Leguminose are a rich 
tribe; but I found very few Proteacee at Moreton Bay ; not 
above four or five. You may observe, in my paper published, 
in Jameson's Journal, that very fine fossil-bones are found on 
the Darling Mountains. I have sent a specimen to Mr. 
Richard Owen, who had kindly given me an introductory 
letter to Sir Thomas Mitchell of this colony.
