[72] PROFESSOR STOKES, ON THE EFFECT OF THE INTERNAL FRICTION 

 Baily's results with the spheres at the end of the short rods. 



Here again the differences between theory and experiment are extremely small. In the 

 case of the pendulum No. 61, Baily's two results 1 - 901 and 1-513 appear to be inconsistent, as 

 not agreeing with the formula (155). 



60. The following table contains the values of t, k, and k t deduced from the given data, 

 and employed in the calculations of which the results are contained in the two preceding tables. 

 It is added, partly to facilitate a comparison of the circumstances of the different experiments, 

 partly to assist in the re-computation of any of the experiments, or the detection of any 

 numerical error which I may have committed. I may here observe that I have not, generally 

 speaking, re-examined the calculations, except where an error was apparent, but that each step 

 requiring addition, subtraction, multiplication, or division, was checked immediately after it 

 was performed. I have not thought it requisite to check in this manner the taking of loga- 

 rithms or antilogarithms out of a table. 



Values of t, k, and k x employed in the calculation of the theoretical results employed in 

 the two preceding tables. 



The corrections for confined space employed are, for the spheres, (AAr), 0-0115, 0-0321, 

 0-1013; and for the rods, (A&0, 0-009, 0-002, 0000. These corrections are to be added to the 

 values of k, k x given in the preceding table before going on with the calculation.
