the cephalopods swallowed in large quantities by the Cetacea. As 
evidence, he points to the fact that several molluscs exhale a pro- 
nounced odour, which lasts after their death and even desiccation. 
The ancients are known to have utilized various species for the sake 
of their odour; and M. Jourdain suggests that the action of the 
biliary products upon the cephalopodic perfume may modify it and 
result in the production of ambergris. 
Lemon-grass Oil.—A sample of Ceylon oil of lemon-grass 
examined by Dodge * was found to have a sp. gr. of 0°886 at 22° 
and 0°8955 at 15°°5. On distillation, the boiling-point was found 
to range between 200° and 240°, a small residue not being volatile 
at the latter temperature. The principal fraction came over between 
220° and 225°C. 
The identification of a new species of Vanilla, V. ensifolia, Rolfe, 
from New Granada, a specimen of which is in the herbarium of 
the Pharmaceutical Society, has now been confirmed by the author- 
ities at Kew, and its botanical analysis fully described in the 
‘Kew Bulletin, No. 66, p. 141. The species is a very distinct 
one, easily recognized by its narrow sword-shaped leaves +.
