analysis of alcohol and sulphuric ether. The constituents of alcohol 

 are as follows : — 



Carbon 51-98 



Oxygen 34*32 



Hydrogen 1370 



100-00 



This result seems to show that alcohol is composed of 



Atoms. 



Oxygen 1 



Carbon 2 



Hydrogen 3 



6 



An atom of it, according to this statement, would weigh 2-89S. 

 This composition is very simple, considering that the number of 

 constituents of alcohol amounts to three. 



The constituents of sulphuric ether are. 



Carbon 67-9S 



Oxygen 1 7'6'2 



Hydrogen 1-4-40 



100-Oa 

 This result seems to show that sulphuric ether is composed of 



Atoms. 



Oxygen 1 



Carbon 5 



Hydrogen 6 



12 



So that, if the analysis of Saussure be correct, sulphuric ether 

 contains twice as many atoms in its composition as alcohol. The 

 weight of an integrant particle of it, according to this statement, 

 would be 5-547. 



IX. Analysis of IFaters. 



Bouillon-Lagrange and Vogel have published an elaborate 

 analysis of the sea-water that washes the different coasts of France. 

 The following table exhibits the results of their analyses : —
