(k.) The sample of turpentine used was kindly furnished 

 me by Prof. J. H. Long of the l^orth Western University, 

 who had had it prepared in his laboratory from pure spruce 

 gum. It had been rectified over sodium and boiled at 156°-5— 

 157°'0 (uncorr.) under a pressure of 745"^'"^ of mercury.
