The samples when prepared should not be unnecessarily 
exposed to the sun, but will not be injured in any way 
exposure to rain. They will if anything, be improved by 
immersion in water. 
The above method was employed when preparing the sample 
which I forward as Exhibit 1. At this season of the year it is 
diffieult to obtain large enough eren of milk for extensive 
experiments, and the specimens e to show are in 
consequence too small for MM etes It is, however, 
my intention to continue the experiments on which these notes 
are based when the rains begin and the trees yield more sap. A 
further report will then be submitted should any new features 
present themselves. 
Exhibits Nos. 2 and 3 are of unwashed milk coagulated by 
pressure, but as an insufficient weight was applied, they show a 
cellular structure, and are also not free from impurities. 
Exhibits Nos. 4 and 5 are of shade-evaporated, unwashed milk, 
and are of fair quality. This method, however, cannot well be 
applied during the rainy season without ‘the application of artificial 
heat, which I have proved to give MER Rr: results 
Exhibits Nos. 2, 3, 4, and 5 are the results of ecrit 
experiments which. were carried on with a view to p the 
possibility of adopting, for the paom H of West African 
rubbers, the process dsa in notes already dinis) 1 to the 
Government of this Colony (see Government Gazette, Colony of 
Lagos, February, 1888). 
Exhibit No. 1 shows that the method indicated has i 
certain extent successful, even under extremely adverse 
stances. It will, however, be for experts in England to ep i 
the good and bad qualities of the samples, and to declare the price 
that it VP to command in the English market. 
These notes have been aii limited to the consideration of 
certain eon to apply the method above described t up e 
preparati ion of india-rubber ies the juice of the “ Abba” 
ere is now on hand a series of experiments on the “Ibo” vite 
juice, which may be further reported on when complete, but at 
present no results have been arrived at of sufficient definiteness to 
warrant a detailed report 
It is important to remember that the results here noted have 
been obtained from one series of experiments only, and are not to 
.be considered as in any way final. They serve to prove the 
possibility of applying a simple and inexpensive system of 
preparation to ican rubbers which has already produced good 
results elsewhere. It will s be asincere p to me 
them to the preparation of india-rubber for the Euro opean market, 
and any question addressed to me in writing will also meet with 
attention, and will be answered as fully as my slight knowledge 
of the matter may permi
