deposits a residue which soon crystallises by simple cooling without the 
necessity of sowing it with a crystal. This residue was therefore almost 
entirely composed of thymol. After rccrystallisation, the crystals had still 
a slight reddish coloration, but the manner of their preparation, their melting 
point (49.3”-50.5°C.) and their odour are sufficient for their identification. 
We do not think that the essential oil of Ocimum gratissimum L. has pre- 
viously been studied, but thymol, which, moreover, has hitherto scarcely been 
observed except in the Labiatre, has nevertheless already been recorded (see 
E. Gildemeister, Les Huiles essentielles' 2nd French Edition, p. 502) in the 
essential oil of another Ocimum, O. viride. — (Scien. and Indus. Bull, of Roure-

A sti'ongly-scented, perennial, lierbaceons, erect plant, l-2ft. 
high, softly patently hairy. Stem sometimes woody below. 
Branches erect, ascending or spreading. Leaves oblong obtuse 
or acute, l-S^in. long, variable in breadth, base narrowed ; 
margin entire or subserrate, hairy on both surfaces and minutely 
dotted, petioles |-lin. long. Floral leaves sessile, ovate- 
lanceolate. Racemes very slender 6-8in. long ; pedicels slender 
as long as the Calyx. Calyx short, two lower teeth very long- 
awned, longer than the broadly oblong upper, lateral broadly 
ovate, shorter than the lower. Corolla very small, scarcely longer 
than the Calyx. Filaments exserted, knee villous. Fruiting 
Calyx -J-in. long on a slender pedicel, broadly campanulate,

compressed, nearly smooth, pale-red, brown. 
Uses : — The leaves have expectorant properties, and their 
juice is used by native physicians in catarrh and bronchitis.
