DEPARTMENT OF ZOOLOGY

Dear Josh:

Our Department of Zoology is faced with the pros-
pect of securing two or more staff members during the
next two years. As you may know, John Gregg is now at
Duke and Franz Schrader retires at the end of the 1958~
1959 academic year. There is further a likelihood that
we will be able to employ an additional man. There are,
of course, limitations on rank and we would be able to
offer an Associate Professorship only if we were mighty
certain about the quality of our choice. More likely the
appointments would be at the Assistant Professor's level
with a salary ranging between $5500 and $7000,

Although appointments in chemical embryology and
chromosome cytology have been or will be vacated, and al-
though we would hope to get someone who can help with our
undergraduate teaching, these considerations need not dic-
tate our selection. We frankly feel that we must be very
careful in these appointments to secure men of real dis-=
tinction; certainly the appointees should be expected to
develop into biologists better than any of us now on the
staff. Of course we realize how hard it is to recognize
true promise in a young scientist and we would appreciate,
therefore, your advice,

With all best wishes,

Sincerely yours,

—hhners

Francis J. Ryan
Professor of Zoology
