PHYSICAL GEOGRAPHY. 



The subjoined table and plan will give you the results of this survey, 

 without adjustment by the method of least squares, which may be applied 

 if the work should be carried further. The values marked * were 

 obtained from the U. S. Coast Survey. 



Latitudes, Longitudes, and Azimuths. 



It is proper to say that the latitude of the Shattuck observatory, Dart- 

 mouth college, as obtained by this survey, differs only 2" from the latitude 

 as determined astronomically by Prof. Young, and the longitude differs 

 only 1 ".25 from the astronomical longitude as far as has been yet deter- 

 mined ; and even this discrepancy is no doubt due to the station error
