Observations on the Relations which exist between the Force, 

 Construction, and Sailing Qualities of Ships of the Line. 



With a former number of the Journal of Science*, we gave 

 a brief disquisition on the force of ships-of-war ; we shall now 

 prosecute our inquiries, and endeavour to shew in what manner 

 the force influences and connects itself with the theoretical 

 construction and sea-going properties of such vessels. 



In the construction of a ship-of-war, it becomes a matter of 

 imperious necessity to consider the relation between its military 

 and sailing qualities ; for it is to very little purpose that the 

 ship possesses the former, if it have not the latter to take them 

 into action and to render them fully available and effective. 



As the limits of a single memoir preclude us from entering 

 into the proposed discussion relatively to all classes of ships-of- 

 war, we shall at present confine our inquiries to those which 

 are denominated ships of the line, reserving for a future paper 

 a similar task in relation to frigates and smaller vessels. 



The easy service of a piece of artillery, as we have already 

 seen in our former paper, is dependent on its weight and 

 calibre, the maximum of which, for sea service, we have therein 

 endeavoured to indicate, from the examination of some facts 

 with which we have been furnished from the practice of our 

 own and foreign naval artillerists. But, however true this 

 maxim is, with regard to a single gun, it requires to be modified 

 when another gun is placed on each side ; for the juxta-position
