one which falls within my province, the former may safely be left to 
the medical profession in the colonies. 
For ringworm, the seeds of Vatairea guianensis are made use of in 
British Guiana. 
As a tonic in flatulent indigestion, boiari root seems to find general 
acceptance in British Guiana. 
The following, from their poisonous properties, also seem worthy of 
chemical investigation : aramata, coroocoroo and moraballi bark, 
devildora root, haiari root (Lonchocarpus densiflorus) and the seeds of 
Cacoucia coccinea. 
Excellent specimens of chillies were exhibited from Natal, and both 
chillies and capsicum in great variety in nearly all the West Indian 
Courts and in British Guiana ; in the latter Court, Tonka beans, as fine 
as those of Para, were also shown. 
In the Montserrat Court, the Montserrat Company exhibited a 
specimen of oil of lime leaves, which had a peculiar fragrance of its 
own, quite distinct from that of neroli. Apparently the only specimen 
of oil of bergamot in the Exhibition was shown by the same firm. 
The principal official oils exhibited were castor oil and olive oil. The 
former was shown from nearly all the West Indian Courts, British 
Guiana, South Australia, Ceylon, Fiji, and the Seychelles, but only that 
from the last-named colony possessed the clearness and brilliancy to 
which we are accustomed in this country. 
A large number of non-official oils were exhibited in the different 
Courts, some of them being obtainable in large quantities from more 
than one colony. This was the case with carapa or crab oil, which was 
shown in the British Guiana and Trinidad Courts, and is a product also 
of Western Africa. It has a bitter taste, and is used by the natives as 
an insecticide, a property which, if retained when the oil is saponified 
might be turned to useful account. 
Numerous specimens of cocoanut oil were shown in several Courts 
that from Seychelles being very white, and a specimen in the British 
Guiana Court was not only very white, but unusually solid, and was 
pronounced by experts to be the best in the Exhibition. 
Of those official in the British Pharmacopoeia, copaiba was exhibited 
in the British Guiana Court. The specimens were of a pale colour and 
good consistence, but it is remarkable that it does not appear to be 
recognised as a commercial variety in this country. 
A kind of elemi was shown in the British Guiana and West African
