II. Measurement of the Base Line near Ban' 



galore. 



This base was executed by Lieut. Warren, of 

 H. M: 33d Regt. then one of iny assistants ; and 

 was intended as a datum for extending the triangles 

 to the Malabar coast : and also as a base of verifica- 

 tion to the triangular measurement brought from the 

 base near Madras; and it appeared that, by continuing 

 the compUtatKms the whole distance, and making 

 this base one of the sides of the last triangle, the com- 

 putation exceeded the measurement only '^■^ inches.
