Mr. Hamilton obferved the end with a telefcope of thirty 

 inches focus double objed-glafsj magnifying power about 120. 



My fon obferved it by projedion on paper, with the telefcope 

 of a fmall equatorial of about feven inches focus. 



Not being yet furnifhed with a micrometer for meafuring the 

 diftances of the cufps, I obferved the appulfes to the fpols, pro- 

 pofing to determine their places by the equatorial; but clouds 

 coming on immediately after the eclipfe, I was difappointed, and 

 fhould be extremely obliged to any perfon that may have fettled 

 them on that day for a communication. 



Both Mr, Hamilton and I obferved a diftortion and difcolor- 

 ation of the fpots as the moon's limb approached them ; and this 

 effedl took place at" fuch a diftance, that I think it cannot be 

 attributed to the infledion of the rays of light, but feems more 

 like the operation of the lunar atmofphere. 



Mr. Sutton obferved this eclipfe at his obfervatory at Drum- 

 condra-hill in Lat. 53. 22. 45.
