Jan. 26, 1857.] DK. LIVINGSTON'S ASTRONOMICAL OBSERVATIONS. 269 



for I find they must be repeated, as the assumed longitude some- 

 times is a degree in error ; therefore at least two, but generally 

 three, approximations will be needed. 



Thus you will perceive that the only residual errors will be 

 chargeable to the eccentricity or index-errors of the sextant, and to 

 the errors of the lunar tables ; and as Livingston unfortunately 

 did not visit the Cape, I have had no chance or opportunity for 

 examining the instniraent. 



I do hope that Livingston's merit will be acknowledged by the 

 Crown in a substantial form He is a poorer man than he was 

 fourteen years back, when he landed in Africa. Without reference 

 to higher motives, he has rendered services to science, and perhaps 

 to commerce, such as few men have rendered. His constitution has 

 been seriously injured by thirty-one attacks of fever. In fact, it 

 would be difficult to find another whose claims on public gratitude 

 are so strong." 



Yours, dear Sir, truly, 



T. Maclear.

2. Notes on the Geography of Burma, in illustration of a Map of that 

 Country » By Capt. Yule, of the Bengal Engineers, f.r.g.s. 



In 1855, Capt. Yule had been sent by the Government of India to 

 Amarapura, as secretary to Major Arthur Phayre, then j>roceeding 

 on a mission to that Court. In drawing up a report of the mission 

 and of the information collected by its members, he had found a new 

 map of the country to be much wanted in illustration of his subject, 

 and this had led him to undertake the compilation in question. 



The paper gave some account of the history of the geography of 

 those countries, to which shape was first given by the mission of 

 Col. Symes in 1795 ; and especially by the collections of Dr. 

 Francis Buchanan, who accompanied that mission. The most im- 

 portant additions to our knowledge were made by the journeys and 

 surveys of various officers, especially of Wilcox, Grant, Pemberton, 

 Eichardson, Hannay, and Macleod, between 1826 and 1837. The 

 revolution at Ava, in the latter year, interrupted all such acquisi- 

 tions for many years. 



Some of the chief materials used in the new map, were, a survey 

 of the new British province of Pegu, undertaken by Lieut. Wil- 

 liams, of the Bengal Engineers, and still in progress ; a new survey 

 of the province of Martaban, by Mr. Hobday ; a survey of the river 

 Irawady to Ava, by Capt. Eennie and Lieut. Heathcote of the
