Ok, I'll go to the library and find the original I copied mine from, and
post the dates. I'm fairly sure it came out of Scientific American. Our
library has them bound back to 1850. I'll also see if I can get a friendly
typist to reproduce the article and put it on the web so anyone who's
interested can get it.
