These figures give an average for the eight men of 5 feet 1} inches, 
the tallest being 5 feet 2} inches and the shortest 5 feet 1 inch, witha 
variation of 14 inches only. The two chest measurements were 36 and 
33 inches, and the corresponding hip measurements of these two men 
were 314 and 31 inches respectively. These chest measurements are 
not to be taken as representative, as both men were exceptionally well- 
built. 
Like the Sakais, the span of the outstretched arms is also greater 
than the height. The mean span is 5 feet 3°28 inches, being 1°43 inches 
more than the mean height, while the excess of the span over height is 
one-forty-third of the height. 
Only one woman was measured, and she was rather taller than the 
tallest of the Sakai women. 
The variation in the stature of the male Semangs is much less than 
amongst the Sakais. This uniformity of height is a thing that strikes any 
one at once. The same thing is recorded by Mr. Mann of the Andamese. 
The averages given by the above measurements seem to indicate that 
the Semangs are a slightly taller race than the Sakais, but more ex- 
tended observations are necessary before this point can be established. 
SIGHT. 
These observations were taken with the test-spots used in the 
British Army. They are square black spots measuring one-fifth of an inch 
and are spaced at distances of one-fifth of an inch from one another. 
The black spots are most conveniently placed in the centre of 4-inch 
square pieces of white cardboard, each card having a different number 
or arrangement of spots on it, the numbers running from 2 up to 6. 
The spots occupy the central square-inch of each card, and there are in 
the pack that was used twenty-three cards in all. These cards are easy 
to make; all that is required is to cut the card up into 4-inch squares, 
then rule the central inch, in pencil, up into fifths of an inch, take some 
Indian ink and a paint brush and paint in, say, four of the squares, leaving
