The corrections of the chronometers were determined by Mr. 

 Paine for Boston State House, from transit observations of Mr. 

 Bond, at Dorchester ; those for Philadelphia State House, by eastern 

 and western altitudes of stars, observed at the High School Observa- 

 tory, by Messrs. Paine, Riggs, Walker, and Kendall, with the Trough- 

 ton's sextant, circle, a Pistor's sextant, and a sextant (maker's name 

 unknown) reading to 10". Those for Washington were made by
