ECLIPSE OF THE SUN, JUNE 16, 1806. 301 



The luminous circle on the edge of the moon, as well as the 

 rays which were darted from her, were remarkably pale, and 

 had that bluish tint, which distinguishes the colour of quick- 

 silver from a dead white. 



I attempted to make observations on the different stages of the 

 eclipse, but for the want of a meridian, and glasses of sufficient 

 powers, I am sorry I could not make them with the accuracy I 

 wished. I however send them as they are, — they may possibly 

 be of some use among the collections from other quarters. I 

 have also taken some pains to ascertain the extent of the moon's 

 shadow, in a northerly and southerly direction. The best in- 

 formation I have obtained is from Judge Thorn of the County 

 of Washington, who assures me that the northern edge of the 

 shadow passed nearly aiong the south bounds of Campbell's 

 patent in the town of Granville, which on my map of the 

 State, lies in latitude 43° I 1 -!' and longitude 0° 45' east of the 

 meridian of New-York; and from Johannes Miller Esq. of the 

 county of Orange, who determined the southern edge of the 

 shadow in the town of Montgomery, to have crossed the road 

 leading from Ward's bridge to Goshen, three miles and five 

 chains, counted from the bridge. This will be in latitude of 

 about 41° 30' and longitude 0° 14' west from the meridian of 

 New-York. The middle of a straight line between those two 

 points, falls on Hudson's river, in latitude 42° 26' which is 

 near the village of New-Baltimore, at which place, therefore, 

 the centre of the shadow must have passed, that is about fifteen 

 miles below this city. 



The following observations on the eclipse of the sun, June 

 16th, 1806', were made in the city of Albany, in latitude 

 42° 38' 42", longitude 73° 47' west from Greenwich. 1 he 

 latitude has been ascertained by a series of observations on stars 

 near the zenith, chiefly a Lyra and Capclla, with a sector made 

 forme by the late David Rittenhouse. The longitude I com- 

 puted by taking 75° 09' for Philadelphia, and deducting 1° 22' 

 for the difference between Philadelphia and Albany. This 

 difference is deduced from surveys connecting the two places. 

 I reguia'ed my clock by observations of equal altitudes of the 

 sun, taken with one of Ramsden s best brats sextants, furnish-
