She has definitely got to the point where large-scale genetic analysis is possible, and its connection with problems of differentiation in this particular type of organism is obvious. ‘D) lonwevalwy If you have any immediate answer to this suggestion, please either write to her d¥rect at the above address or to me: En Chalet, St. Luc, Valais, Switzerland, where I shall be till the end of August.
