[ALUG] Launch xterm with smaller font than specified in .Xresources

Dear All, On my system, fonts are served up by XFS. The font I usually use in xterms is set in my .Xresources file as follows XTerm*VT100.Font: -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO10646-1 XTerm.Font: -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO10646-1 XTerm*Font: -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO10646-1 However, for one particular task, I want to launch an xterm with a much smaller font. The command xterm -fn fixed Gets me part way there, but I want an even smaller font than that. Any ideas, please? -- Thanks, Dan
