210 COFFEE ANALYSES AND MANURES. 
The ‘‘ Dominant element” indicated by the above is 
certainly potash; carbonic acid (of no consequence, 
however) coming second ; phosphoric acid third with 
10°3 per cent against 55°1 of potash. Magnesia and 
lime both show well, as does sulphuric acid; but 
oxide of iron and chlorine are of little account. If 
we went by this analysis alone we should use a 
manure consisting of one-half at least of potash ; the 
remaining half being made up wainly of calcic phos- 
phate of magnesian lime in addition to nitrogen. 
Turn we now to Mr. Hughes’ analysis of beaus and 
parchment skin combined. Its history, as given by 
the chemist himself, is as follows :— 
‘*The following is an analysis of parchment coffee 
which was obtained from some cherries sent me from 
the district of Badulla. The amount of moisture pre- 
sent is possibly high as compared with average estate 
coffee received in Colombo, but on this point future 
analyses must decide. The sample was very carefully 
prepared, the beans being separated from the pulp, 
allowed to remain in contact with water the necessary 
time, well washed in fresh water, afterwards dried by 
exposure to the sun, and the enclosed in a well-corked 
bottle and shipped with the samples of soil. The 
analysis is only a partial one as regards the proportions 
of the different organic constituents. Sugar, albumen, 
tannin, caffeine, cellulose, mucilage, &c., are included 
under one heading. The separate determination of each 
would be of interest in comparing different qualities 
and varieties of coffee, but is not necessary for our 
present purpose. The quantity of nitrogen contained 
in the total organic portion has, however, been very 
carefully determined, as well as the respective quantities 
of the important mineral constituents. The analysis 
has been made with a view of ascertaining to what 
extent coffee exhausts the soil.
