'j6 Capt. Kater’s experiments for determining the 
kept by Mr. Browne, it was found that a considerable 
change had in fact suddenly taken place from moisture to 
dryness ; and, so great was the derangement of the pendu- 
lum from this apparently trivial cause, that it became neces- 
sary to move the second weight. This was accordingly done, 
and the following experiments made for again bringing the 
number of vibrations to an equality.
