Marblehead, Nahant, Marshfield, Hyannis, a village in the town of 

 Barnstable on the south side of Cape Cod, and Bullock's Neck on 

 the east side of Seekonk or Providence river. The extreme results 

 differed less than one foot, though the stations embrace a distance 

 of seventy or eighty miles of sea-coast. The point chosen for the 

 mean height of the sea, was half way between high-water and low- 

 water, as observed on the same day ; care being taken to repeat the 

 observation on days when the sea had been for some time (appa- 

 rently at least) without agitation by high winds or storms. 



After applying the reductions for the sea-level, and the standard 

 length and temperature, the following results were obtained for the 

 length of a degree of the meridian.
