Table I. — Comparison of the Melting-points of the Anilides and Amides 



of some Fatty Acids. 



Table II. — Comparison of the Melting-points of the Oximes and Ketones 



of some Fattv Acids. 



As the series is ascended the higher members have a smaller difference 

 in melting-point between ketone and oxime than lower members.
