Abstract
The tail hairs of various mammals were subjected to different chemical treatments for different times and their xβray diffraction photographs obtained. The powder rings recorded in the case of buffalo hair disappeared after the fiber was treated in acetic or formic acid for 48 hr. On the other hand, inorganic salt solutions were practically inert.
