[printed material on left side of page, see original] Dr S L Katz [stamped, Mar 17 1973] Peds/Duke see (1) Has anyone made that point in print? (2) Is your reply a considered one? Or that you think such considerations should influence our public health policy? (with which I would agree) Wouldn't smallpox in fact make a rather reasonable harassing and or clandestine weapon? (In a world that has seen massacres at Lod airport and a Khartoum embassy!) In fact I'm sorry you even articulated the idea in print in what might be an instructive fashion. I've had plenty of self-doubts on the same score. [written in right margin in different handwriting, KATZ, Samuel]
