298 PRINCIPLES OF NAVAL ARCHITECTURE TO AERONAUTICS. 
longitudinal stability, it was not the intention in the paper to take the ground that 
at the present stage of development, the transverse stability is the more important. 
What the paper was intended to bring out is the fact that before the introduction 
of ailerons or warping wings, such as was the case when Langley conducted his 
experiments, that the longitudinal stability was greater than the transverse sta- 
bility. Langley depended for transverse stability almost entirely on the dihedral 
angle. In other words he placed the center of gravity of the total weight a con- 
siderable distance below the center of buoyancy of the supporting surfaces. This 
naturally resulted in a reduction of the longitudinal stability because of the pendu- 
lum action resulting from the low placed center of gravity as referred to in the paper. 
THE PRESIDENT:—We will now close the meeting, with the thanks of the 
Society to Messrs. Roberts and McEntee for the papers which they have presented 
to us. 
The President requested that the members of the Council convene for a meeting, 
after which the meeting was adjourned.
