round, and four feet below the surface. The sea that enters 

 rushes in with considerable velocity. The water rises in the 

 pit through the sluice, to the height of two feet, and is then 

 discharged through some means not yet ascertained. Mr Bab- 

 bage said that the waters which disappeared might go into vast 

 hidden receptacles not yet filled up, or else the volcanic agency 

 supplying heat might, as the waters descended into the earth, 

 cause eruptions. — Professor Wheatstone shewed his speaking- 

 machine, and explained the pi'inciples upon which this inge- 

 nious machine is invented. — The business of the meeting con- 

 cluded by the thanks of the Association being given to the pre- 

 sidents, &c., and to the public institutions in Dublin for the 

 accommodation granted to them, and especially to Sir John 

 Tobin of Liverpool, who gave one of his fine steam-vessels for 

 the conveyance of members of the Association to and from Ire- 

 land. 



Thus terminated the fifth meeting of the British Association 

 — a meeting equally interesting and effective with those that 

 preceded it, but out-doing them all in splendour and in displays 

 of national character.
