2 ) The spec, gravity mentioned applies to sweet orange oil; the oil of bitter 

 orange has the specific gravity dtso 0,854 to 0,857. 



s ) Owing to the content of wax-like constituents, the oil generally forms only 

 a cloudy solution with 90 per cent, alcohol. 



Orange blossoms Oil {Oleum aurantii florum). Colourless 1 ) to 

 brownish; C1150 0,870 to 0,880; soluble in 1 to 2 parts alcohol; the

Origanum Oil, Cretian {Oleum origani cretici). Somewhat 

 viscid; yellow to red-brown; di 5 o 0,920 to 0,980; soluble in 3 parts 

 dilute alcohol, the solution is coloured violet or (more rarely) green by 

 ferric chloride. 2 vol. oil of Cretian origanum must make a clear

Parsley seed Oil {Oleum petroselini). Yellowish to pale greenish 

 somewhat viscid; when shaken with water, or in the cold, a solid crystal- 

 line body 1 ) is sometimes separated off; di 5 o 1,050 to 1,10.

Pine Needle Oil from Pinus Pumilio {Oleum pini pumilionis). 

 Colourless to bright yellow; diso 0,865 to o^S 1 ); makes a clear or 

 slightly cloudy solution with 5 to 7 vol. alcohol. 



1 ) Comp. the present Report, p. 62. 



Pine Needle Oil from Pinus Silvestris {Oleum pini silvestris) 1 ). 

 Colourless to yellow-greenish; di 5 o 0,880; soluble in 5 to 6 parts alcohol. 



*) As the oil distilled from the needles of Pinus silvestris L. is not at all a 

 commercial article, and as moreover the name Oleum pini silvestris is an old but 

 incorrect designation of "templin oil" (oil from the cones of Abies alba), it would 

 have been better to have included Oleum templim\ whose spec. grav. lies between 

 0,85 and 0,87 (15 ). 



Rue Oil {Oleum rutae). Colourless or yellowish; d^o 0,833 to 

 0,840; solidifies at about -f- 8°; soluble in an equal vol. alcohol. 



Sage Oil {Oleum salviae). Mobile; yellowish; d 15 oO,9i5 to 0,925; 

 soluble in every proportion in alcohol. 



Sassafras Oil {Oleum sassafras). Mobile; yellowish to reddish
