meters, iuto decimal fractions of the whole leugth of the plate, and apply 

 the correspondinft- angles to similar plates of any size. 



This can be done in the case of the square plate A, by simply multi- 

 Inlying its sides and its C by two, and thus obtaining the column 2A, 

 as if for a square 180""" on a side. If the reasoning were correct then 

 the a in the column 2A should be comparable with those extrapolated 

 from B and C, but the relation between them is not simple, so that care 

 must be taken in applying this data to other cases.

X indicates that the an<rle is indeterminate or that the plate oscillated so much as to show that it
