a few months yielded 3491 hookworms of which 30 only were A. duodenale 
and the remainder N. americanus, an ancylostome index of 0-86. 
A group of 35 Tamil coolies engaged in road repairing in Kuala Lumpur 
were found to be harbouring 2870 hookworms of which 59 were A. duodenale, 
the remainder N. americanus, the percentage of ancylostomes being 2*0. 
Polynesia. 
Fijians represent a mixture of two stocks, Melanesian and Polynesian. 
The typical Melanesian is exemplified by the Papuan, while the Polynesian 
is represented by the Tongan or Samoan. 
Fusion of the two stocks is going on to-day in Fiji. With the object of 
learning what the species formula of the autochthonous Fiji population was, 
the remote and rather inaccessible village of Nasoqo in the mountains at the 
head waters of the Rewa River was visited and a group of 15 persons treated. 
Among 546 hookworms obtained not a single A. duodenale was encountered, 
the ancylostome index being nil (a few A. ceylanicum were found as in the 
mountain villages of Java but these are derived from dogs and have no bearing 
on the A. duodenale index). 
The worm counts made on the town dwelling Fijians (village of Nausori) 
confirm the findings at Nasoqo, but, as we have seen, they show evidences 
of contaminative infection by A. duodenale from North Indian sources, that 
is, from plantation and factory coolies working and living in the same 
village. 
Until further and more detailed survey work is done in Polynesia we may 
assume that the primitive ancylostome index in this region is nil. 
This observation at Nasoqo is of the greatest value, for it was made on 
a pure uncontaminated population of two fused South Sea ethnic stocks. 
Chinese, Japanese, Portuguese and East Indian immigrations have been for 
several years altering the primitive index of South Sea Islanders in the towns 
and villages near plantations. 
The absence of A. duodenale in Fiji among uncontaminated autochthones ' 
indicates that races carrying A. duodenale as the Egyptians, Chinese, Burmese, 
Japanese and North Indians have never colonized there, and it shows that 
the Fijians, wherever their stock originally came from, did not come from 
north of 20" N. latitude and have never been in contact with people from 
those latitudes. 
This is a matter of considerable interest in view of the probably erroneous 
opinion held by some that the Polynesians originated in northern Africa or 
Asia and that during their migrations southward they sojourned in Fiji. 
Additional surveys are urgently needed in Polynesia before we can speak 
confidently in this matter. 
To one who has been intimately acquainted with Malays and Javanese 
and has seen something of the Papuans, Solomon Islanders, Fijians, Tongans, 
Samoans and Maoris there is beyond certain linguistic similarities nothing to
