October 22, 1965 Dear Virginia: Hoeber Publishers have asked me to act as guest editor for one of their publications of CLINICAL OBSTETRICS AND GYNECOLOGY. As you probably know there are four hard bound volumes of such symposia per year. Enclosed is a copy of the proposed format of a symposium on Human Teratogenesis which I have outlined. Would you be willing to put some of your pearls in print for obstetricians and gynecologists who use these volumes extensively, The length of the article would be about 10 printed pages. I probably do not have to tell you how honored I would be to have you contribute to this particular issue on this particular subject. The deadline for getting the manuscript to me would be about March 15. I will be looking forward to hearing from you soon and hopefully, favorably. Best personal regards. Sincerely, Elsie R.
