Numeric and PIL Files?

[W. Watson]

I'm looking at some files that are related to Python:

Python-2.4.2.msi
Numeric-24.2.win32-py2.4.exe
PIL-1.1.5.win32-py2.4.exe

What are the three files? msi is the install file for MS, but what are the 
other two, and where can I find them? The first one no longer seems 
available on the <http://www.python.org/download> site.

          the end of his life in his 90s and contemporary of Charles
