Dear Miss Scrymgour,

    Thank you for your letter of December 17 and the material of the Brachina manuscript. I hope it can be published soon.

    I have checked the magnification of the figures; Fig. 10 is 23x, Fig. 14 is 27x, and Fig. 15 is 83x on the xerox copies you sent me. The reference you inserted for Bowen and Schairer is correct.
 
    I have read your contribution and find it quite informative and have nothing to add. On the middle of p. 2 you pencilled in "striae" instead of "grooves" in describing the texture of the frontal surface; I agree that "striae" is probably preferable. Your acknowledgement of Dr. Schmitt's contribution seems quite appropriate.
   
    The only change I would like to make is in the order of authors in the title. I would like to add Mr. Jarosewich's name (and eliminate it from the acknowledgements), since I feel his analysis is a major contribution, and I would prefer the order J.E. Johnson and J.M. Scrymgour followed by Eugene Jarosewich and Brian Mason. Jim Johnson deserves great credit for recognizing the meteorite as the second chassignite, and we would not have had the opportunity of studying this almost unique meteorite if it had not been for him and you.

    With warmest regards and best wishes to Jim and yourself.
   
    Sincerly,

    Brian Mason
    Curator
