The vapour-densities were determined by the Dumas 

 method, corrections for expansion of the glass globe being- 

 made and great care taken to ensure accuracy. As will 

 be seen, the agreement between the theory and the values 

 actually found is quite close enough. 



Some of the fatty acids, viz. Acetic Acid, Butyric Acid, 

 and Valerianic Acid, have been shown to enter into chemical 

 combination with these hydrocarbons. In the Table the 

 percentage of hydrocarbon found in such compounds is given.
