of course avoidable. 
One oil was exhibited in the Jamaica Court which is 
highly extolled by Mr. FIELD. I refer to it, as the tree 
whence it is produced grows here easily, and is by no 
means uncommon. We know it as the horse-radish or 
seringah, but its botanical name is Moringa pterygo- 
sperma. Its seeds yield oil of Ben or Behen, described 
as an exquisite oil, and ' one which, though appa- 
rently devised by nature expressly for the perfumer, 
seems to have been singularly neglefted. Mr. PiESSE, 
in his " Art of Perfumery," is enthusiastic in its praise. 
It would be invaluable to the flower farmer, who by the 
process known as enfleurage, i.e., submitting blossoms 
to the aftion of oils or lard, extrafts their perfume. 
It is also said to be the basis of macassar oil which is, 
or was, so fashionable. 
Referring to ' enfleurage, the Jamaica Court shewed 
fine specimens of tuberose and jasmine pomades. Surely 
British Guiana could do likewise with behen oil. These 
and other pomades and oils, for which the demand in 
England alone is enormous, could be manufa6lured here, 
and a profitable industry created. Mr. Field's remarks 
on this subject are worth laying to heart. u Why," he 
asks, H should not our own colonies supply us ? Why 
" should all our citron, bergamot and orange oils come

Carapa or Crab oil, it appears, would be a fine and 
valuable oil but for its sickly and persistent odour. It 
proved impossible to get rid of this defe6l — blowing hot 
air through a pint of it for 24 hours was ineffectual. It
