What may well have happened is that the BoundingBox computed for
the second file is not right for the extent graphic for some
reason connected with using the embedded fonr.

Make a "test" copy of the second eps file, and then see what
happens if you edit it as follows: **using a plain-text editing
program, not a word-processor**!!

Somewhere in the eps file (either near the beginning or at the
end) you will find a line which looks like

  %%BoundingBox: 66 442 536 767

(taken from one of my own). These are the (x,y) coordinates, in units
od points, of the lower left and upper right hand corners of the
graphics **as planted by the program that made the EPS**. Since
in most PostScript display applications, the BoundingBox is a
"clipping path", normally you will not see anything that lies
outside the BoundingBox (even though it is present in the file
as PostScript commands).

The general format of the above line is

  %%BoundingBox: llx lly urx ury

so the lower left corner is at (llx,lly) and the upper right corner
is at (urx,ury). So, if you graphic appears clipped at the bottom.
try lowering the bottom edge. This means using the editor to reduce
the value in llx (at least -- maybe other adjustments may be needed).

So, for example, with the above %%BoundingBox: line, you might try
dropping it by 0.25 inches (18 points):

  %%BoundingBox: 48 442 536 767

since 48 = 66-18. If that works, then your problem has been idenitified,
and then someone wioll be able to give you specific help.

Best wioshes,
Ted.
