Oct. 24 Paraffin melted at 44-60. 



„ 31 ,. „ (thermometer not observed). 



Nov. 7 „ „ at 44-70. 



„ 11 „ „ at 44-75. 



The experiments now described have been made chiefly 

 by Mr. F. Kingdon, assistant in the Physical Laboratory of 

 Owens College. The most probable conclusion to be de- 

 duced from them appears to be that the melting point of 

 this specimen of parafBn has become somewhat lowered 

 since the experiments began. 



It is proposed to continue these experiments for some 

 time longer ; but in the meantime it has been thought 

 desirable to describe the method of research, as this may be 

 of interest to observers of melting points.
