In the course of the voyage, several changes 

 occurred among the officers, which it may be well 

 to mention here. 



In September, 1826, Lieutenant Hawes inva- 

 lided : and was succeeded by Mr. R. H. Sholl, the 

 senior mate in the Expedition. 



In February, 1827, Mr. Ainsworth was unfortu- 

 nately drowned; and, in his place, Mr. Williams 

 acted, until superseded by Mr. S. S. Flinn, of the 

 Beagle. 



Lieutenant Cooke invalided in June, 1827 ; and 

 was succeeded by Mr. J. C. Wickham. 



In the same month Mr. Graves received infor- 

 mation of his promotion to the rank of Lieutenant. 



Between May and December, 1827, Mr. Bowen 

 and Mr. Atrill invalided ; besides Messrs. Lunie, 

 Jones, and Macdouall : Mr. W. Mogg joined the 

 Beagle, as acting Purser ; and Mr. D. Brail y, as 

 volunteer of the second class. 



Mr. Bynoe acted as Surgeon of the Beagle, after 

 Mr. Bowen left, until December, 1828. 



In August, 1828, Captain Stokes's lamented 

 vacancy was temporarily filled by Lieutenant Sky- 

 ring ; whose place was taken by Mr. Brand. 



Mr. Flinn was then removed to the Adventure ; 

 and Mr. A. Millar put into his place.
