ECLIPSE OF THE SUN, 1869.

1869.] 



Ozone was much in excess. The ozoneonieter, placed at 

 4 P.M, and removed at 7 P.M., s^howed a tint corresponding to 

 3 of the scale, while the usual measure, exposed from 4 p.m. till 

 7 P.M., showed somewhat less than 2. 



The observations of the sky spectrum, by the spectroscope, 

 were not carried out so well as was desirable. The only dif- 

 ference observable was a dulness in the colour of the red ray. 



Peltier's Electrometer indicated but a very slight disturbance 

 in the electric state of the atmosphere. The temperature of the 

 air was observed every five minutes, as also the temperature of 

 evaporation. The Barometer was read eveiy fifteen minutes. 

 From these combined observations the gas3ous and hygrometric 

 state of the atmosphere have been reduced. — (See Table 1.)
