officers will, no doubt, be anxious to contribute 

 their share to the scientific character of the survey. 



" 1 have now exhausted every subject to which it 

 can be necessary to call the attention of an officer of 

 your long experience ; and I have, therefore, only 

 further to express my conviction, that if Providence 

 permits you to retain your wonted health and 

 activity, you will pursue the great objects of this 

 expedition with all the energy in your power, and 

 with all the perseverance consistent with a due 

 regard to the safety of His Majesty's Ship, and to 

 the comfort of your officers and crew.
