I cannot add anything to Herbernar's report which is clear and thorough. = The whole structure, including the presence of martensite, is consistent = with the quick cooling of condensed drops of iron vapor. There is enough = carbon in Canyon Diablo to account for martensite, and only a very small = percentage of carbon and phosphorus would account for the Steadite - the = Fe-Fe3C3Fe3P eutectic. If you use these data in a published paper, please give Herbenar all the = credit, because I did nothing in the way of research. I want him also to look over the specimen from Peru and then I will send = them to you, with the specimen. Cordially, (Stuart Perry - name is missing as this is the file copy. The original se= nt to Nininger would have been signed by Perry) The numbered photos were taken by Bidigare; the four lettered ones, A to = D, by John F. Swing at the engineering laboratory at Ann Arbor. ------=_NextPart_001_0008_01C41ECE.29D5A4E0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <HTML><BODY STYLE=3D"font:10pt verdana; border:none;"><DIV><FONT size=3D2= > <P>(Stuart Perry to Harvey Nininger letter, Perry's File copy)</P> <P>F= ebruary 8, 1951</P> <P> </P> <P>Dear Nininger:</P> <P>In this packag= e I am sending you Herbenar's report on the iron granules, and the photos= taken under his direction; also three or four earlier photos taken by my= assistant at Ann arbor.</P> <P>I cannot add anything to Herbernar's repo= rt which is clear and thorough.
