A First Study of the Burmese Skull 
In the position of the skull on the board when tlie scriber was passing over the 
glabella and occiput the warjoing of the board would have no effect. If we add 
to the contour measurements 1 mm. which the defective Klaatsch was responsible 
for docking, the agreement is seen to be very close indeed. 
The length as obtained from horizontal contours does not tally with the above, 
of course, since their plane does not pass through the occipital point. It is on the 
average 2 mms. less.

In the case of the auricular height as given by the sagittal contours, we have to 
allow for some shortening due to both contour tracer and drawing-board defects. The 
tracer passes over the bregma inclined at about 60° : the bregma is therefore thrust 
about 0-5 mm. nearer to the auricular point ; in marking the auricular point the tracer 
is not held aslant, and the shortening of the distance in question at this point will 
be about 0-3 mm. ; i.e. about 0-8 mm. in all through the defect in the tracer. The 
warping of the board would affect both terminals and further shorten the line by 
about 1 mm. The addition of 1-8 mms. to the sagittal contour means brings them 
into closer agreement with the craniophor means except in the case of C ? ; and the 
difference of 1-2 mms. there obtained is not serious. With the transverse contours, 
neither source of error displaces the mid-point of the auricular line which is one 
terminal, but they combine to displace the apex, our estimate (already used) being 
about -8 mm.

In marking the terminals of this measurement (nasion and alveolar point), the 
positions of the Klaatsch were parallel and pointing in the same direction. The warp
