468 COSMOS. 



eclipsed Sun, belong to the outermost gaseous envelope of 

 the central body. 1 These projections became visible on the 

 Moon's western edge as it proceeded in its motion towards 

 the east (Annuaire du Bureau des Longitudes for 1842, 

 p. 457); and disappeared again when they were covered on 

 the opposite by the eastern edge of the Moon. 



On a subsequent occasion the intensity of the light of 

 these projections became so considerable, that they could be 

 perceived within the corona through telescopes, when veiled 

 by their clouds, and even with the naked eye. 



The form of some of the projections, which were mostly 

 ruby or peach-coloured, changed with perceptible rapidity 

 during the total obscuration; one of these projections appeared 

 to be curved at its summit, and presented to many observers 

 the appearance of 'a freely suspended detached cloud* near the 

 point, and resembling a column of smoke curved back at the 

 top. The height of most of these projections was estimated 

 at from 1' to 2. ; at one point it is said to have been more. 

 Besides these tap-formed projections, from three to five of 

 which were counted, there were also observed riband-like 

 streaks of a carmine colour, extended lengthways, which 

 appeared to rest upon the Moon, and were often serrated. 1

1 Compare the observations of the Swedish mathematician, 

 Bigerus Vassenius, at Gottenburg, during the total eclipse of 

 May 2, 1733, and the commentary upon them by Arago, in 

 the Annuaire du Bureau des Longitudes, for 1846, pp. 441 

 and 462. Dr. Galle, who observed on the 28th of July at 

 Frauenburg, saw *' the freely suspended cloud connected with 

 the curved, hook-formed gibbosity by three or more threads." 



* Compare what a very expert observer, Captain Berard, 

 saw at Toulon upon the 8th of July, 1842. " II vit une bande 

 rouge tres mince, dentelee irregulieremeut." (Annuaire du 

 Bureau des Longitudes, p 416.) " He saw a very narrow red 

 band irregularly serrated."
