OF THE SUN, JUNE 16, 180(3. 26*7 



grecs distance. — The lunar disk was ill defined, very dark. 

 forming a contrast with the luminous corona; with the tele- 

 scope I distinguished some very slender columns of smoke, 

 which issued from the western part of the moon. The ring- 

 appeared concentric with the sun, hut the greatest light was 

 in the very edge of the moon, and terminated confusedly at 

 6' distance. 

 -II 1 ' 00' 20", (chron.) Ohscrved the appearance of a ribhon 

 or border, similar to a very white cloud, con- 

 centric with the sun, and which appeared to me to belong to 

 its atmosphere, 90° to the left of the moon. 



ll h 00' 28", (chron.) Observed the illumination of various 

 points in the disk of the moon on the same side. 



1 l h 00' 30", (chron.) The illumination of the moon was ve- 

 ry distinguishable, shewing the irregularities of 

 its disk, the colour of a palish yellow. — In the moment of the 

 sun's re-appearance, the versed sine of the illuminated segment of 

 the moon, was equal to 4. part of the apparent diameter of Ju- 

 piter, observed in opposition with the same tube, 



ll h 00' 34" 8, (chron.) End of total darkness, 90° on the left; 

 the sun appeared as a very bright star of the 

 third magnitude; at the call of the 35", such was the intensity of 

 the light that I abandoned the telescope, having received a vi- 

 olent impression on the eye: from the appearance of the first 

 ray, to the moment when it became insupportable to the eye, 

 was so instantaneous, that I have estimated it at less than T j^ ot 

 a second. ' It is to be remarked, that this observation was made 

 without a darkened glass, with tube No. 1, which magnifies 

 90 times, and is remarkably clear. 



0" 21' 38", (chronometer.) End of the eclipse. 



During the whole of the eclipse, the sky was very clear, 

 not a single cloud was visible, and there was scarcely any wind. 

 The sun was without a spot. A little dew fell during the dark- 

 ness; five or six principal stars and planets were visible. 



Mr. John Garnett (of New-Brunswick, New-Jersey,) who 

 also observed the eclipse with an excellent telescope of Dolland, 

 with a triple object glass, and 2 T 7 - °- 5 . inches aperture, tube No. 

 1, of the same power as the one I used, was placed four or
