that if the misleading term " balata" were dropped, and 
relations opened directly with the manufafturer, a very 
large trade could be done in this article. Balata, or 
gutta, suffers from coming into the market as a different 
material from gutta, and under another and less recog- 
nised name. It has been bought by speculating dealers 
at a nominal price as bullet-tree gum, and sold to the 
manufa6turer at the market price of the best gutta. 
It is also desirable to adopt some system of coagula- 
tion of the fluid gum which would advance the 
quality of the produ6l, or minimise deterioration by 
oxidation. It appears that ozone, which, to a certain 
degree, is beneficial to human life, is the cause of rapid 
decay in gutta and rubber — a thin leaf of the former 
falling to dust in strongly ozonized oxygen. It is recom- 
mended, therefore, to mould the produft into thick com- 
pa6l masses rather than into thin sheets. 
The India-rubber shewn in the British Guiana Court was 
considered sound and of good quality. Mr, BOLAS believes 
that much of it was obtained from the Touckpong tree, 
which is a variety of Sapium biglandulosum. Another 
sample shewn was from Hancornia speciosa. The 
rubber from Hevea Spruceana was submitted by 
Mr. HOLMES to well-known brokers, who stated 
that it had never come into the London market, 
and that if well cured, it would command 2/ to 2/2 per lb. 
The sample of Hancornia or Mangeibera rubber was 
cleaner than the samples usually sent to the London 
market, and was valued at 1/10 to 2/ per lb. 
The samples of Gum Animi, or Locust gum, were con- 
sidered exceptionally fine. Mr. Bolas remarks that the 
value of this material is quite understood by varnish
