Dear Dr. Jago:

     Your letters of June 15 and August 8, 1977 to Brian Mason have been referred to me for reply.  Your letter of August 8 actually arrived here several days ahead of your letter of June 15.  I am returning the envelope used for the earlier letter, as it may interest you.  It was sent surface mail as printed matter.

     I have looked over our specimens to IVB meteorites with a view to supplying material for your research.  The following notes give my initial reactions, but I will be glad to hear from you further on these.

     Under separate cover you are being sent a small slice of our Hoba specimen USNM 3390.  You may remove a small amount of this specimen for your work, as described in your letter.  One surface of this piece before it was sliced looked like it may have been removed from the main mass by an oxy-acetylene torch.  Buchwald saw this sample and did not report heat alteration.  You might want to polish the surface and examine it optically before you take your samples for TEM.

     We have only one small polished section of Ternera, and I would be reluctant to have that used for sampling for destructive analysis.  I notice that there is also a small sample at UCLA.  Perhaps John Wasson would be willing to part with a small amount for your work.

     We have only one small polished section and an exhibit specimen of Iquique.  I am reluctant to disturb the exhibit without exceedingly strong justification.  Perhaps you could find some other source for this meteorite.

     Our slice of Tlacotepec is large, but it is also an exhibit specimen.  We have none of this meteorite in our research collection.

     We have a 60g slice of Weaver Mountains (USNM-3145) that could be lent to you for sampling purposes should you be interested.  It may just duplicate Tawallah Valley, however.
