340 Mr. Harvey's experimental inquiries relative to the 
intensity of the starboard section on the upper and lower 
decks, and the corresponding intensity of the middle section 
on the latter deck. The minimum intensity was at b\ in the 
same plane as the greatest intensities of the middle and star- 
board sections on the main deck. 
On the lower deck, and in the same longitudinal plane, the 
most striking difference in the intensities of the starboard and 
larboard sections was found at the stations H", H", the for- 
mer being 69.96, and the latter 135.63 ; the difference be- 
tween the bearings of the ship's head at the two observa- 
tions being only a point and a quarter. The last mentioned 
intensity was also found to be the greatest in the whole section ; 
and was situated in the same transverse plane as the minimum 
intensities of the middle and starboard sections on the same 
deck. The line of stations H w x 111 H" was immediately over 
the after part of the shot-locker. The least intensity was 
discovered at e'", in the same vertical plane as the minimum 
intensity of the starboard section on the main deck. 
The following table exhibits the maximum, minimum, and 
mean intensities of the stations assumed in the three longitu- 
dinal planes, arranged according to the sections in which 
they are found.
