3. If we had specimens of the leaves, flowers, and fruit of the 
iree from which the milk was obtained, we might then be ina 
position to suggest a treatment that would afford satisfactory. 
results present we have no dei. pan n which to work, and 
the matter cannot be carried any furt. 
4. We would suggest -m steps s Rie to procure specimen 
of tarb f flowers, and fruit of all rubber plants in the district i in 
which you are setae, and we enclose instructions for 
collecting and preparing such specimens, so that they might 
arrive in this country in a suitable state for examination.

eec ru: of the tin were strongly acid ; on pouring out the

cutting off the lid. The part coagulated was treated by itself.

portion which separated in this case bins "end T by itself. Both 
products were very sticky, and becam 8 the washing 
process was continued ; they tdiimately. aedes on unma nage- 
able for the subsequent stages of drying, &c.; the substance is 
quite unsuited for any ordinary india-rubber manufacture 
y destructive distillation it does not yield esiétclibusifs 
which is the principal characteristic of caoutchouc or india- 
rubber. The distillate more closely resembles in smell that of 
some principles, balsams, &c., which yield cinnamic acid 
leaving the same exposed in open vessels, and E what 
forms on the surface from time to time so as to increase the 
chance of further evaporation, &c. If it be intended to send 
these natural juices for examination, it will be best to add 
mmonia freely, so as to neutralise any acid which may be 
generated whilst in transit. 
The Resident DUM adds : “ i; o do not see our way to make
