Figure 5. Orgueil after HF-HCl treatment. (.4) One of 2 transparent spherical par- 

 ticles seen. Irregular black-brown material is adherent to the surface. (B, C, D) Amorphous 

 residue remaining after HI-'-HCl treatment. Most of this material is amorphous carbon with 

 traces of MgF2 and organic matter. The line is 20 n in length.

It is evident that there are discrepancies between our findings and those of 

 Nagy et al. In an attempt to resolve these differences, we visited the labora- 

 tories of Claus and Nagy at their invitation. They examined our material 

 and we examined their material. It became evident that there were several
