Y scs nite for the obizaction of the folar nr og was 
,a.three-fect reflecting telefcope, with {pirit levels ; a 
ial ‘aduated, femi-circle of about 41 inches. radius, and rack 
motions for taking altitudes; and a glafs.micrometer, ; fitted 
with rack motions, I believe of Dolland's conftru&tion, having 
a nonius graduated to .:.. part of am inch: A reflecting tele- 
fcope of near two fect ; and a profpe&t-glafs:of three feet four 
anches length, which I mounted on a convenient ftand.

y houfe ; and from that time to the day of the eclipfe, I was 
«onftantly employed in taking correfponding altitudes of the 
fun with my telefcope, and conftru&ing a meridian-line. 
Our obfervations of the ecliple were as follow :
