On the Measurement of the 
[Nov. 
After the successful termination of the war with Tipu Saheb, Brigade Major Lamb- 
ton brought forward his plan of a geographical survey of that part of the peninsula. 
His first idea was confined to throwing a series of triangles across from Madias to 
the opposite coast, but in the prosecution of this object his enlightened mind soon 
resolved to combine with it the measurement of as many degrees ot latitude as the 
limits of his survey might enable him to subtend : his design was fortuitously 
seconded by the arrival in India of the duplicates of the instruments employed b) 
General Roy, and it met with the cordial support of Lord Clive and his council. 
Major Lambton had in 1801-2 established a first scries of triangles on a me- 
ridional arc of one and a half degree, 35 miles to the west ot Madias. He subse 
quently abandoned this line, and selected the Dodagontah meridian depending 
upon a twice-measured base line at Bangalore. The object ot this substitution 
was to obtain a clear run to the southernmost point of the peninsula, vbich 
effected by February 1809, making a line of 4° 50' ; a suspicion having however 
arisen on the calculation of the resulting length ot a degree in the latitude ot 
dagontah, that the plummet had been subject to some deviating influence, a ne 
was carried northward from Pagar to Guti in 1811, and the seiies was ex ^ ^ 
3 degrees further north to Damargidda, by the winter of 1815 ; making in 
arc of nearly 10 degrees in length. 
During the three following years, owing to the Pindari war, the establish 
was employed upon the subordinate arcs of Lavendrug and Kylasgeih. ' ^ ^ 
operations wereonlv recommenced in 1819 ; at which period Captain Everest 
associated in the grand work. For three years in succession the disasters cncou 
ed by the whole party were of the most discouraging description. Minute 
country was one impenetrable jungle, hitherto entirely unexplored; tie ^ QnJ 
was uncongenial both to Europeans and natives, who were oveicome by P ^ ^ 
and sickness. Colonel Lambton came to Calcutta ; and Captain 
soon after driven to the Cape of Good Hope, to recover his healtn. . g j n 
In 1822, the veteran Colonel was again in the field, measuring a _^ 0 
valley of Berar, near a place called Takal Klidra, where lie was j°^ e ^ a | cU tta, to 
Everest. He had dispatched his medical attendant, Dr. Voysey, via 
Agra, for the purpose of reconnoitring the country along w nc 1
