Dear Mr. Hyland:
I am returning under separate cover corrected second galleys 69-79 inclusive.
In regard to the preprints of part of the book: the members of the seminar do not desire to purchase individual preprints. Hence, I wish to order six copies struck off from Chapters III, IV, V, and VI for their use. If convenient for you, those should be here by February 17. The charge for them is to be billed to me.
I am looking forward to receiving page proof soon.
