The mean height K of the drops is 3*629 millims., from which, 

 and by means of equations (12) and (13), it follows that the 

 acute angle of mercury against glass, when a = 55*03 milli- 



grammes, is 



(9 = 51° 8'. 



7. Drops of a liquid of specific gravity a v in another liquid 

 of specific gravity <r 2 , behave similarly to drops of mercury in air 

 when (r 1 >o-c l . 



In this relation I examined bisulphide of carbon and chloro- 

 form in water which was placed in a trough whose sides were 

 made of plate glass and cemented with sealing-wax. The drops of 

 liquid introduced into the water did not come into contact with 

 the sealing-wax. Without this precaution, u n will be found 

 less than in the following Tables, in which the observations are 

 collected. The measurements were made as described in § 5. 

 The notation is the same as there, except that K, k, and K — k 

 are now positive magnitudes.
