9. The observations on flat drops of olive-oil in absolute alco- 

 hol were conducted similarly to those on drops of mercury in 

 the same liquid, and gave the following results : —

The capillary constant of the common surface of olive-oil and 

 aqueous alcohol of nearly equal specific gravity is also interesting 

 on account of Plateau's experiments. 



I determined, in a glass which with the liquids had not been 

 disturbed for a year or more, and in which the aqueous alcohol 

 had obtained a greater specific gravity than the olive-oil ; the
