Setting font size in emacs

[Vincent Cocco]

Just received the latest Linux Journal and was reading the Matt Welsh
article on emacs.  He goes into how to customize and set your own key
bindings.  What I'm interested in knowing  (which I hav'nt been able to
figure out from the available docs that I have) is how to set the font
size within emacs.  When I get into into it from X (under Linux, of
course)the default font size is too large; I want it to be the same,
standard size as the rest of my windows.
Anybody know how to set this (I figure it must be a lisp command
within the .emacs file.

Any help would be appreciated.
Thanks
