The first line of this table represents that element in the flora of 
the island wherein the inflaence of the three adjacent districts may be 
assumed to act indifferently ; the second line that wherein the influence 
of the Arracan district is to be eliminated and only Pegu-Malayan and 
Andaman-Nicobar influences (presumably equally) prevail; the third 
line that wherein Pegu-Malayan and Arracan-Assam influences prevail, 
while Andaman-lSTicobar influences do not act ; the fourth contains the 
element representative of Pegu-Malayan influences alone ; the fifth that 
representative of purely Andaman-Nicobars influences ; the sixth that 
indicating purely Assam-Arracan influences ; the last, like the first, in¬ 
dicates an element wherein the influences of the three areas act in¬ 
differently but in the opposite way. As however this element (the 
endemic) is here only represented by one species, it is not convenient 
or useful to employ it in computation, and since Diamond Island is 
geographically inseparable from Arracan this species is tieated as 
indicative of Arracan influence. 
Reasoning from particulars the Andaman influence is stronger 
than either the Pegu or the Arracan influence is, so far as positive evi¬ 
dence goes, for there are here three exclusively Andamanese species as
