same principle, with the exception of the fittings for war, being armed with only 10 

 brass swivels, one pounders ; she was constructed by Mr. Lang for the packet ser- 

 vice between Falmouth and Malta, and built under his superintendence by Messrs. 

 Curling and Young ; was employed in that service at first, about nine months, under 

 the command of Lieutenant Baldock ; she was afterwards fitted as a yacht for the 

 Marquis of Anglesea, at Dublin, since which, on the Marquis leaving Dublin, she 

 has been employed as the yacht for the Lords Commissioners of the Admiralty to 

 perform their sea duties ; her dimensions are as follow :

Her two engines are 60 horse power each, made by Messrs. Maudslay ; her pad- 

 dle-wheels by Mr. Morgan ; her performance is considered to be superior to any 

 vessel of her size in proportion to the power of her engines, which are very small for 

 a vessel of such dimensions ; her velocity has been proved in several instances where 

 she has beaten her opponents ; one vessel of 237 tons, two engines of 50 horse 

 power each * ; one vessel of 400 tons, two engines of 90 horse power each f ; an- 

 other, 700 tons, two engines 150 horse power each \ ; one of 237 tons, two engines 

 of 50 horse power each $, &c. She behaves well at sea in bad weather, and is a good 

 sea-boat under canvass alone ; she is rigged with three masts, similar to the Medea. 

 Nothing further need be said by way of description of the vessel, as her form, method 

 of fastenings, fittings, &c., are all exhibited in the drawings. Vide the Plate.
