1820.] and the Planet Venus. 415 



Meantime. Ther. 



naked eye, was about 36° to the E. of the 

 sun, and shone with a full orb of a bright gold 

 colour nearly 10 minutes. The breeze conti- 

 nued fresh. So interesting was a sight of 

 this great -eclipse and the planets at this 

 moment, that all classes of people here were 

 looking through their smoked and tinged 

 glasses,both from their gardens and house tops. 



2 — 60i The difference in the increment of light was- 

 scarcely distinguishable. The sky remained 

 clear, and of a dark blue colour ; and the 

 distant clouds near the horizon lost part of 

 their light, and descended into the lower 

 atmosphere, as is frequently observed at or 

 soon after sunset. The birds too, both small 

 and great, were observed flying over, as if 

 hastening to their respective nocturnal rest- 

 ing places. 



2 15 — 60 A Fahrenheit's thermometer in the neighbour- 

 hood that was more exposed to the S.E. 

 breeze, sunk to 58° about this time, being the 

 minimum diurnal temperature. The index of 

 the hygrometer advanced to 57°. The light 

 perceptibly increased, and cast curious but 

 imperfect shadows of objects on the leads. 

 A lofty cirvocumulus sprung up in the vicinity 

 of the sun, and stretched to the N. and S. 

 horizon. 



2 30 — COi- The temperature rose again ; and the light was 



about the same strength as at one, p. m. 

 The breeze died away ; but a broad band of 

 cirrus appeared to the westward. 



3 — 63-i- The eclipse drew to a close. Barometer, 30*12 



inches. 

 10 — 64 End of the eclipse. The sun at the same time 

 lightly shaded by a passing cirrus, but not 

 sufficient to prevent a clear view of the sepa- 

 ration of the limbs of the sun and moon. It 

 appeared that the solar hght was not now so 

 brilliant as at 15 minutes after the beginning 

 of the eclipse. 



4 — 66 A faint solar halo in an attenuated cirrostratus. 



5 — 63 Cu/nulostratus formed near the western horizon. 



6 — 61 The whole hemisphere overcast by the last 



modification. 

 6 30 — 60 The temperature the same as at 15 minutes past 

 two, p. m. The minimum temperature in the 

 night was 52°, that is, 2° above that of the 

 preceding night.
