The crude oil of D. fascicularis contains free alcohol, probably 

 geraniol, as practically no constituent was present boiling below 

 222°. 



By referring to Schimmel & Co's list of known constituents of 

 essential oils, Report, April, 1897, we find that geraniol occurs in 

 the oil from the following: — 



Fresh flowers N.O. Rosacese (Roses). 



Herb N.O. Geraniacese (Pelargonium sp.) 



Grass N.O. Graminese (Andropogon sp.) 



Flowers N.O. Rutacese (Citrus sp.) 



Flowers N.O. Anonacese (Cananga sp.) 



Wood N.O. Burseracese (Bursera sp.) 



To this list may now be added; Shrub N.O. Myrtacese (Dar- 

 winia sp.) 



With the doubtful exception of the oil from Eucalyptus citrio- 

 dora this appears to be the first time that geraniol has been found 

 occurring in plants belonging to the Myrtacese, although this 

 genus consists so largely of oil-yielding plants. 



Distillation of the original oil. 

 100 cc. of the crude oil of D. fascicularis was distilled under 

 atmospheric pressure, only a few drops came over below 170°, 

 principally water ; the thermometer then rises rapidly with an 

 occasional drop to 215°, between 215° and 222° 5 per cent, distilled, 

 three fractions were then obtained : 



1. 222° to 230° obtained 32 per cent. 



2. 230 „ 240 „ 32 



3. 240 „ 270 „ 22 



Specific gravity first fraction -897 at 20° 

 „ second „ '906 „ 20° 



„ third „ -913 „ 20° 



Another distillation gave — 



222° to 230° = 34 per cent. 



230 „ 235 = 47 



235 „ 240 =67
