Dear Dr. Mason,

We have been working in this laboratory for some time on determination of major, minor and trace elements in various natural substances by the method of neutron activation analysis. We have determined several elements like Na, K, P, S, Si, Mo, W, Re, Mn, Cu, Mg, Ca, Re, Fe, Ni, Hg, Se, Zn etc. in various materials like steels, biological and plant materials and Indian ores. We are desirous of extending these methods to analysis of meteorites and similar geological specimens. In this connection, we would like to request you to spare us some meteorite samples if it is possible. We are not in a position to exchange similar specimens with you, but would be grateful if you can donate some specimens to us. If any expenditure is involved in this transaction, we would be willing to bear it. 

With best wishes,

Sincerely yours,
