micellae of the organic substance. The holes corres- 

 pond to ellipsoids of revolution and are aligned with 

 the axis of the bone. The present interpretation ap- 

 pears to be in agreement with the properties of the 

 bone and not in contradiction to the knowledge 

 derived from the wide-angle diflYaction pattern. The 

 latter corresponds to the crystalline units. From 

 their aggregation derives the homogeneous body 

 with holes responsible for the low-angle x-ray dif- 

 fraction pattern (13, pp. 164-165).
