both by its own motion, and by that of the ocean which is so subject to its power, 

 restores again the heat which had been converted. Thus the normal condition 

 of temperature is preserved, not only throughout the changes which render it 

 latent and sensible, in the generation and condensation of vapour, but also in 

 its conversion into mechanical power and its reproduction, in the phenomena of 

 the tempest and of the billowy sea.

The next Table contains the constant corrections to be applied to the pre- 

 ceding results. The first column gives the diameters of the tubes ; the second, 

 the instrumental corrections obtained by comparison of the several instruments 

 with the Dublin standard by means of portable barometers ; the third, the re- 

 ductions to the sea-level, calculated at the rate of -0011 of an inch for each 



* The pressure for January, at Westport, is the mean of 17 days only, viz., Jan. 15-31 ; and 

 that for August, at Dublin, is the mean of 15 days, viz., Aug. 1-14.
