OBSEEVATIONS OE THE ECLIPSE. 
I. Observations with the wnassisted Eye., and with the Telescope. 
A splendid day on Sunday the 15th was succeeded by one of the grandest and most 
awful thunder-storms I have ever witnessed; and the 16th was cloudy, almost without 
intermission. The day previous to the eclipse had been completely overcast, with the 
exception of a short interval about noon ; but even then the sun could only just be seen 
through a cloud somewhat thinner than those which obscm’ed the rest of the heavens. 
The climate had therefore proved anything but propitious, and every interval of fine 
weather had to be diligently made use of for the adjustment of the instruments and 
the prosecution of observations. Fortunately an opportunity had presented itself on 
two days for practice in observing the sun with the Dallmeyer between 1 h. 30 min. and 
4 P.M., and for special practice at about 3 o’clock. It was ascertained that duriug the 
progress of the eclipse the radius bars would have to be changed ft'om one leg of the 
tripod-stand to the other, and arrangements were made to prevent the necessity for 
doing this during or near the period of totality. 
To this instrument I had fitted an eyepiece of my own contrivance, which I described.
