(1) improved precision; (2) higher speed of operation;
(3) increased scope of applicability. If for
the purposes of research it is necessary to obtain
twenty solutions of a certain differential equation
these solutions might easily require several
months* work by a mathematician with ordinary
-computing aids, two days' work with the present
machine, and possibly two hours' work with the
proposed new model. The present machine has
been in continuous use on a wide range of problems
for four years. It has been reproduced at
the University of Manchester, England, and the
University of Pennsylvania has recently put a
unit into operation. Anotherimit is unc>r construction
at the Astrophysical Institute at Osio,.
These machines are used in studies on cosmic
rays, geophysics, seismology, electrical machinery,
acoustics, astrophysics, and radiation.
Fellowships and Grants in Aid
During 1935 the Foundation continued to contribute,
although on a lower level than in previous
years, to the fellowship programs in the biological
and the physical sciences administered by
the National Research Council. An appropriation
of $75,000 was made for the support of fellowships
in these twofieldsduring the year 1936-
37. During 1935 there were sixty-three persons
working under these fellowships in the physical
