Arcs of lyOwitz were not seen from that station, although in 

 all other features the observer recorded the same general 

 details as were visible in Media. It is quite possible that the 

 arcs were obscured from that point of view by clouds of smoke 

 overhanging the city or on account of an irregular condition 

 in the strata of frozen moisture. It will also be noted that 

 the arc formed by the outer halo is not so great as was 

 observed at Media, and that it occupied a somewhat different 

 position relative to the line passing through centre of the sun
