First thanks to all of you for your responses, either on- or off-list.

It turns out Siep's remark above solves the problem: run, in 
Terminal.app,

	sudo updmap --disable wolfram.map

then pdfLaTeX the .tex file including the figures that use the 
Mathematica fonts. Everything, then, works as expected and the font 
Math1 looks fine in the output.

The problem is apparently that I had installed the Mathematica fonts, 
from my Mathematica 4.1.5.0, in all the appropriate subfolders of 
texmf.local, and that I had accordingly run

	sudo updmap --enable Map wolfram.map

afterwards (wolfram.map -- the .map file, not the fonts -- is included 
in Gerben's teTeX, at 
/usr/local/teTeX/share/texmf.tetex/dvips/misc/wolfram.map). This was 
mostly for testing purposes, as I don't actually use Mathematica fonts 
directly in my TeX documents.

Now, this seems to have an unfortunate side effect when figures (in 
either .eps or .pdf format), containing subsetted Mathematica fonts, 
are included in a TeX document not otherwise using these fonts: it 
turns out (this is my interpretation, I may be wrong) that pdfTeX 
insists on replacing the subsetted (and possibly re-encoded) versions 
of the fonts included in each .pdf graphics by the version, installed 
in the teTeX tree, specified by wolfram.map, according to

	Math1 Math1 <Math1.pfa

dvips, on the other hand, is clever enough to leave the .eps graphics 
alone, and to only perform re-encoding and downloading for the fonts 
specified in the actual TeX input, not for those in the included .eps 
files.

Thanks for pointing this out, Siep, I would never have guessed 
otherwise.
