NOTE ON A PARIS PHOTOGRAPH OF THE ECLIPSE.

Figure 301 was obtained at the Paris Observatory, 

 bv MM. Demetresco and Crojes, with a telescope of 

 ten metres focus placed before the siderostat. The 

 Observatorv was some twelve-and-a-half miles 



sun. Some prominences are seen rising out of it, a 

 large one near the bright solar crescent being 

 especially noteworthy. The irregularities of the 

 moon's limb break the chromospheric ring into beads

distant from the central line, and consequently a 

 crescent of sunlight about 8" in width remained 

 uneclipsed. This appears as a confused glare in the 

 picture in consequence of over-exposure. The thin 

 white crescent on the other side of the moon's disc 

 belongs to the chromosphere, not to the body of the 



in a few places. These are analogous to Baily's 

 I)eads. The part of the moon most distant from 

 the solar crescent is seen outlined against a faint 

 light, which is, I think the inner corona. The 

 Paris observers are to be congratulated on obtaining 

 such an interesting photograph.
