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

 the corresponding angles to similar plates of any size. 



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

 plying 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 anfrle is iudeterminate or that the plate oscillated so much as to show that it 

 was in a state of uustable oiinilihiiiiin.
