SOME NEW ENGLAND EUCALYPTS AND THEIR ECONOMICS. 291 



On rectifying the oil only the usual few drops of acid 

 water came over below 175° 0., together with a very little 

 oil containing some volatile aldehydes. Between 175 - 

 188° 0.68 per cent, distilled; between 188-224°, 11 per 

 cent, came over; between 224-265°, 11 percent, distilled* 

 The specific gravity at 15° 0. of the first fraction =0*8589; 

 of the second = 0*8714 ; of the third = 0*9224. The 

 rotation of the first fraction a D = — 34*8°; of the second 

 - 32*6°. Light did not pass with the third. The refrac- 

 tive index at 18° of the first fraction = 1*4812; of the 

 second = 1*4835; of the third = 1*4989. 



Kino* — The kino of this tree agrees in its appearance and 

 reactions with those of E. Sieberlana and allied species. 

 It gives a violet coloration with ferric chloride, slowly 

 changing to a grey precipitate, and does not contain either 

 eudesmin or aromadendrin.
