SHIP.BUILDING. 



produA are to be divided by the immerfed part of the bottom 

 of the fliip. 



it is hence evident, that while the feftion at the water-line 



is the fame, and the volume of the immerfed 

 torn remains alfo the lame, the altitude of the 

 remain the fame, whatever may be the form 



part of the bot- 

 meta-centre will 

 of the bottom. 



The above operation give,^ 14 feet 9^ inches, the hciplit 

 of tlip meta-centre above the centre of gravity of the im- 

 merfed part of the bottom of the 74-gun Ihip, }'/ale 11. 



Now let us fee how the above calctilations in determining 

 the height of the meta-centre above tlie centre of gravity 

 agrC'^s with aftiial experiment ; for theory (particularly in the 

 coiillrtitJliiig ot fliip") that agrees with experiment is only 



to be regarded. We are in this particular indebted to the 

 late admiral Levefon Gower, who direded feveral experi- 

 ments to be made to try the relative liability of the follow- 

 ing Ihips of war, by heeling them with their lower-deck 

 guns out on one fide, and houfed on the other ; and after- 

 wards with their men at tjuarters, the guns remaining ai 

 above.
