These surveys, checked by the numerous latitudes which were 

 taken, and knowing the longitudes of a few points and the magnetic 

 variation which was frequently ascertained, enable us to lay down, 

 with sufficient accuracy for present purposes, a considerably amount 

 Data for a map. of topography. As, however, it is proposed that I shall continue ope-

 both years' work at the same time. For the same reason I propose 

 next year to describe the whole region more fully, so that the present 

 report may be considered as being to some extent only provisional.
