a7id Foreign Ships of War. 43 



guidance in the construction of ships, the elements of the ships 

 of war designed by the celebrated Swedish constructor, Chap- 

 man, are given : they ai-e extremely fine specimens of naval 

 architectural skill. The French and Swedish tables, as here 

 exhibited in English measure, have been calculated by Mr. 

 Read and myself, jointly. 



In a very absurd article on Ship-building, signed " Neptuni," 

 in No. 6, of The Naval and Military Magazine, my plan of cal- 

 culations is characterized, "as a mode of getting the light dis- 

 placement (!), quite impracticable and totally erroneous." It is, 

 however, evident that the miserable writers " Neptuni," or the 

 SeaGods{.'), have never read my plan; or if they have read it, 

 they have not been able to understand it, as they are obviously 

 imacquainted with its nature, and are unequal to passing an 

 opinion on it. They may now see that the work is not im- 

 possible. 



In addition to the synoptical view of ships of war here 

 given, other calculations on them, with the legitimate deduc- 

 tions arising therefrom, will in a short time be published.
