U. S. Ship Vincennes, 



Singapore Roads, Feb. 26th, 1842. 



Sir, 



After leaving the Straits of Sunda, you will be governed by the 

 following instructions, viz. : 



You will proceed to the westward across the Indian Ocean, passing 

 five or six hundred miles to the southward of the island of Panaw, 

 double the Cape of Good Hope, and visit the island of St. Helena, 

 where you will lose no time in filling up with water, and proceed 

 from thence to Rio de Janeiro, at which place you will make experi- 

 ments for dip and intensity, on the island of Enxados, and take on 

 board a sufficient quantity of bread for the passage to New York. 



When you arrive at New York, you will cause all journals, memo- 

 randums, remarks, writings, drawings, sketches, and paintings, as 

 well as all specimens of any kind, to be delivered to you; which, 

 together with your own journal, you will have carefully boxed up 

 and sealed in the presence of two commissioned officers ; marked 

 Exploring Expedition, and hold them subject to my orders. 



On your arrival at New York, you will find orders from me ; or, if I 

 should not have arrived, you will report by letter to the Honourable 

 Secretary of the Navy, sending him a copy of this order. 



You are supplied with Six's self-registering thermometer, with 

 which you will obtain the temperature daily, at the depth of one 

 hundred fathoms, when your morning sights are taken ; at which 

 time you will note in tables the latitude and longitude, the current 

 (velocity and direction), masthead 1 temperature, deck temperature, 

 and temperature at the depth of one hundred fathoms, and at the 

 surface. 



You will examine all shoals, banks, and positions marked "doubt- 

 ful," that may lay in or near your track. 



At St. Helena, you will leave letters informing me of your pro- 

 ceedings, and you will lose no time in making your way to your final 

 port of destination, as it is all-important you should reach the United 

 States at as early a day as possible. 



On dropping your anchor in New York Bay, you will pay to 

 each of your crew ten dollars, and suffer them to leave the vessel at 

 once, as their time will have expired ; and retain only as many as will 

 volunteer to take charge of the brig.
