During our six years' voyage the following changes 

 occurred: — 



Mr. Usborne invalided, in consequence of his 

 wound, in May 1839 ; Mr. Birch exchanged, in 

 August 1839, with Mr. Pasco, into the ' Britomart ;' 

 Mr. Freeze exchanged, in September 1839, with 

 Mr. Forsyth, J into the ' Pelorus ;' in February 

 1840, Mr. Helpman joined the colonial service in 

 Western Australia ; Mr. C. J. Parker was ap- 

 pointed, in December 1840, to Mr. Usborne's 

 vacancy, superseding Mr. Tarrant, who had been 

 doing Master's duty since Mr. Usborne left ; Lieu- 

 tenants Emery and Eden returned to England in 



* This officer I afterwards appointed to the assistant surveyor- 

 ship, (vacated upon my succeeding Captain Wickham,) on account 

 of the active part he had taken in the surveying duties : an 

 appointment most handsomely confirmed by Captain Beaufort. 



f Mr. Keys was always a volunteer for boat work, and is 

 entitled to honourable mention as being, even where all were 

 zealous, of great value upon more than one occasion. 



:j; From this officer's previous knowledge of the duties of sur- 

 veying, having sailed in the ' Beagle' on her former voyage, he 

 proved a very valuable addition to our party.
