The Yeet Eev. Chaeles Graves, D. D., President, in the Chair. 



Eobert McDonnell, M. D., read a paper ''On the Lateral Line in 

 Eishes." 



The Eev. Professor Haughton read the foUoAving paper : — 



Ojs^ the Eain-Eall and Evapoeatiox m Dublin in the Yeae 



1860. 



The observations, of which the following Tables contain the results, 

 were made in Dublin, on the roof of the Magnetical Observatory, with 

 a cylindrical glass vessel, eight inches in diameter, freely exposed to 

 both rain-fall and evaporation. 



1 have added the daily rain-fall, the direction of the wind, and the 

 dew point, observed at 10 a. m. Erom these observations it appears 

 that the evaporation exceeded the rain-fall during the first fifty weeks 

 of the year by 1-62 inches ; the rain-fall during that time having been 

 34-643 inches (to which was added during the last sixteen days of the 

 year 1-239 inches — making a total rain-fall of 35-882 inches) ; and the 

 evaporation during the fifty weeks amounted to 36-263 inches, leaving 

 a balance in favour of evaporation of 1-62 inches. 



During twenty-three weeks of the entire fifty weeks the rain-fall 

 exceeded the evaporation by 1 1-40 inches ; and during twenty-six weeks 

 the evaporation exceeded the rain- fall by 13-02 inches, and in one week 

 they were equal to each other.
