xlii. ABSTRACT OF PROCEEDINGS. 



Oitral is the only aldeliycle present in the oil, as proved in 

 several ways. The crude oil was soluble in an equal volume 

 of 80°/° alcohol, but not in 10 volumes 70°/° alcohol ; it had a 

 specific gravity 0*8095 at 15° O., a refractive index 1*4903 

 at 16° C, and a rotation in a 100 mm. tube of 9*2 degrees 

 to the right. The pinene, which on a final rectification, 

 boiled between 155-157° C, had a specific gravity 0*8601 

 at 15° 0., a refractive index 1*4706 at 20°, a rotation 

 a° + 35*5°, and gave a nitrosochloride melting at 103°. The 

 purified citral obtained both from the crystalline bisulphite, 

 and from the soluble compound, gave in both samples a 

 refractive index 1*4913 at 20° a specific gravity 0*8937 at 

 the same temperature ; it had the odour of citral and also 

 gave the naphthociuchoninic acid for that aldehyde. The 

 non-aid eh ydic portion of the oil had a specific gravity 0*8866 

 at 20°, rotation +13*4° and refractive index 1*4855 at 22°. 

 It was esterised in the usual way for the determination of 

 the free alcohol. Limonene could not be detected, nor 

 were either phellandrene or cineol present. The name 

 proposed for the species is L. Liversidgel.
