SOME NEW ENGLAND EUCALYPTS AND THEIR ECONOMICS. 285 



two fractions were added together and again distilled, 

 when between 155 - 156° 0., 100 cc. came over, and between 

 156 - 159° C. 30 cc. more, or 65 per cent, of the crude oil. 



The specific gravity of the first fraction at 15° 0. = 0*8639; 

 rotation a D = + 25*4°; refractive index at 22° O. = 1*4643. 

 The specific gravity of the second fraction at 15° O. = 08658; 

 rotation a D = + 24*8°; and the refractive index at 22° O. 

 = 1*4646. 



These results confirm those previously obtained with the 

 oil of this species, and the chemical evidence shows the 

 botanical difference between these two trees to be specific. 

 A portion of the crude oil was steam distilled, when over 

 90 per cent, came over. This was practically colourless, 

 had a turpentine odour, and traces of eucalyptol were 

 detected. The specific gravity at 15° C. = 0*8698 ; refrac- 

 tive index at 22° O. = 1*4647; and rotation a D +24*4°.] 



Eucalyptus nova-anglica, Deane and Maiden. 

 "Broad Suckered Peppermint." 



Historical. — It was first referred to in scientific literature 

 by J. H. Maiden, in A.A.A.S., Vol. VII, 1898, p. 541, under 

 Eucalypt No. 2. Specific rank was given it by H. Deane 

 and J. H. Maiden in Proc. Linn. Soc. N.S.W., 1899, p. 616. 



Remarks. — It is well distributed over the New England 

 tableland and is one of the many " peppermints " of that 

 area, being known as white, red, and black peppermints of 

 different localities, these probably referring to its "pepper- 

 mint " bark. 



Timber Tests. — Three pieces were taken, standard sizes 

 3" x 3" x 36", and gave the following results : — 

 Transverse tests : — 1. Broke under a pressure of 4,850 lbs. 



2. „ „ „ 4,400 flbs. 



3. „ „ „ 3,750 lbs.
