Note. — The table readily shows that the relation of the plane of natural curvature to either one of 

 the axes of the cross-section, varies in different hairs, as well as at different pofhts in the same 

 hair.

Figures of the various sections: Oval, 95 sections; approxiniatp oval, 14; round, 1; approximate 

 round, 0; egg, 2; triangular, 1; approximate triangular, 1. 



Note. — The same hair sometimes represented different figures at the three points 

 where sections were made ; for instance, hair Ko. 5, of specimen No. 3, was approxi- 

 mately round at butt, irregular oval in middle, and oval at the end. It may be noted 

 that in specimen No. 3 we have the greatest average length for the long axes and the 

 shortest average length for the short axis of the figures of tho cross-section. Also 

 note the evenness of the average length of short axes of specimens No. 4 and No. 5, the 

 variations being but .0082 millimetres while the long axes varied .0181 millimetres 

 in the same specimens.
