Kohn 1203 Shattuck Avenue Berkeley, CA 94709 Dear Henry: Thank you for sending me the corrected pages of your draft report. I’ve rnarked”a few places that might be improved for technical clarity. I appreciate your patience. I believe our book was mistakenly identified in the task assigned to you. All the technical effort was done by Bill Robison and colleagues. You have wisely reviewed their work rather than our book, but it is still not fully clear in your report. However, this doesn’t detract from your excellent work. Wit best regards, 4 b W.~.
