324 ON THE VIBRATION OF PENDULUMS IN FLUID MEDIA. 



motion, and likewise the particular conditions to which it is 

 subject. 



It would be encroaching too much upon the Society's time 

 to enter on the present occasion into an explanation of the 

 cause of this apparent anomaly : it will be sufficient here to have 

 made the remark, and, at the same time to observe, that when 

 the extent of the vibrations is very small, as we have all along 

 supposed, the preceding theory will give the proper correction 

 to be applied to bodies vibrating in air, or other elastic fluid, 

 since the error to which this theory leads cannot bear a much 

 greater proportion to the correction before assigned, than the 

 pendulum's greatest velocity does to that of sound.
