I think he's poking fun that the mp3 file won't play. It isn't for me anyway..

It doesn't play for me either, using Chromium (the distro pacakge of Google Chrome) on Linux Mint 14. But view source, Ctrl+F mp3, and doing wget on the name of the file worked just fine.

They should really make a lossless .wav or .flac available IMHO, but that's a different gripe...

Did you try downloading it? It works for me. (http://media.smithsonianmag.com/audio/alexander-graham-bell....)
