U. S. Ship Vincennes, 



At Sea, January 31st, 1840. 

 Sir, — 



It becomes my duty, in consequence of the report of the assistant- 

 surgeons of this ship (a copy of which is enclosed), relative to the 

 health and condition of the crew of this ship, to restore you to duty 

 for their benefit, and to obtain all the medical advice in my power to 

 enable me to carry out the instructions of the government. 



You will, after due examination and consideration, relative to the 

 health and condition of the crew, report to me in writing, your 

 opinion in regard to the same. 



I am, very respectfully, 

 Your obedient servant, 



(Signed) Charles Wilkes, 



Commanding Exploring Expedition. 

 Dr. Edward Gilchrist, 



Acting Surgeon, Vincennes.
