No. 135. 



MARCH 29th, 1854 : EVEITIKO. 







Lat. 35 26' N. : Lon. 133 42' E. 



Sun set Gli, 14m. 

 Stronger Light 7A. 28m., &c., to JOA. : Diffuse 7A. 40m. and 9A. 



A very favorable sky for observations. Sun set at 6 h 14 m . At 7 h 14 m a whitish light all along the horizon, but 

 inns higher up towards the Pleiades than at any other part ; 7 h 24 m , there is now evidently a brightness running up 

 beyond the Pleiades, but it is not strongly eneSigh marked to give certain boundaries. At 7" 28 m it is quite distinct, 

 and I get boundaries, as at a.
