Mr. Harvey on Square and 



outer edge of the port; and tlie direction of the shot passed quite 

 clear of the adjacent water-closet. From this situation, the gun 

 was turned towards the opposite quarter of the ship, the line of iire 

 /F, forming with the axis X Y Fig 2, Plate III, the angle/ F Y of 

 30°, the gun having swept over the arc e f of 43°, without the 

 smallest difficulty of any kind. Hence it appears, that the entire 

 range of the arc af, from the point a where the limiting fire of the 

 after broadside-gun commences to the pointy, where the utmost 

 limit of the adjacent stern-gun is obtained, is capable of being as- 

 sailed by an efficient and vigorous fire, from either of the ports 

 here alluded to, or from the port in the quarter of the stern ; and 

 that moreover, the weakness of the quarter, which in the square 

 stern has always formed so essential and important an objection, 

 in the curvilineal stern is entirely removed. It may also be added, 

 that when the gun was trained in the last-mentioned position, its 

 muzzle was only an inch within the outer edge of the port. It will 

 likewise be remarked that the line of fire passes entirely clear of the 

 dressing-room. 



For the purpose of a more convenient reference, the following 

 table is added, the first column of which contains the different 

 angles formed by the lines of fire with the principal axis of the ship ; 

 and the second, the distances of the points of intersection formed 

 by the same lines of fire with the axis, reckoned from the point K, 

 the centre of the circular arc ab e ff e b a which surrounds the 

 stern.
