Jn the different plots which consisted of 4 to 6 vines 
grown < n dead Capucin wood the following analyses show such, 
an individual variation in the composition of the vines that vm- 
less experimental plots are made large enough to cover 1/5 or 
1/lOth of an acre per plot, it will Be diflhcult to determine 
exactly the influence of manuritig on the composition of the 
vines.

In this series of analyses made it has Been proved that the 
proportion of Potash is also sometimes high as well as that of 
lime, that the three elements lime, potash and phosphoric acid 
are aBsorhed By the vanilla vines under experitnent in larger 
proportions when the food is given in the form of a complete 
manure that is to say, that these three elements reach a higher 
percentage in the ash of the vines treated than in the mitreated 
vines ; that the same rule applies to Nitrogen, which is Being 
aBsorBed in greater proportion when the manure is complete 
than when the manure is incomplete. 
However there is a consideraBle variation in the proportion 
of each separate element in treated and untreated vines, and the 
only conclusion which can Be deduced at present is that a high 
percentage of lime and potash appeared in the ash, nearly 50 o/o. 
The other elements exist in small proportions and do not 
seem to have the same importance with regards to the food of 
the vanilla plant with the exception of Phosphoric acid, which 
curiously enough when applied in large quantities, seems to 
enable the vanilla vines not only to aBsorh a greater proportion 
of mineral food But also to contain a larger percentage of lime 
than when coral lime forms part of the manure instead of guano 
(Phosphate of Lime).
