are discussed, it appears probable that ,the acids with an 

 odd number of carbon atoms will behave in the same way. 

 This peculiar behaviour is shown by several of the properties 

 of the fatty acids, including their melting-points and the 

 differences of their boiling-points. 



Biltz found nothing of this nature when he determined the 

 rates of association of the alcohols in benzene solution. It is 

 noteworthy, however, that neither the melting-points nor the 

 differences of the boiling-points of these compounds show a 

 behaviour like that of the aliphatic acids.
