 are situated at 10700 and 12500 (about 11400 and 13320 

 English) feet above the level of the sea. The numerical

 observations, render it probable that the major axis of the 

 Ring of the Zodiacal Light does not coincide with the plane 

 of the Sun's equator, and that the vaporous mass of the 

 Ring, whose molecular condition is wholly unknown to us, 

 does not pass beyond the Earth's orbit (Schum. Astr. Nachr. 

 No. 492).
