Himalayas, so far as the stations within the alluvial plain are 

 concerned, and in order of latitude in the case of those situated 

 on rock to the south of the alluvial plain. The alluvium here is 

 about 150 miles in width, and, on the road section to Khatmandu, 

 the main boundary lies about 24 miles from the outer edge of the 

 hills ; the total width of the Gangetic trough is, therefore, about 

 170 miles. The southern boundary of the alluvium exhibits a 

 peculiarity in this region w^hich, as will be seen, may not be without 

 influence on the deflections of the plumb-line at stations near its 

 southern boundary ; just at the 84° meridian the boundary turns 

 nearly due southwards to the line of the Son River, and eastwards 

 of this numerous outliers of rock rise through the alluvium 

 between the main continuous rock area and a line running about 

 E. N. E., on the continuation of the line of the Son Valley. Over 

 this area the alluvium, between the hills rising from it, is probably 

 nowhere of great depth, and the region as a whole should be in- 

 cluded in the rock, rather than the alluvial, area. One station, 

 Bihar, is situated on a small outlier, which is the last visible to- 

 wards the continuous alluvial plain, another, Teona, is close to 

 the line where it approaches the N-S stretch of the boundary, 

 and a third, Mahar, is on a hill about 15 miles from the line bound- 

 ing this archipelago of inliers. 



Turning to the consideration of the deflections we find that 

 the stations of the alluvial plain show southerly deflections of 

 about 12" ; the most northerly is about 60 miles from the outer
