[emeritus]

I have a facsimile volume of "The Model Engineer" for the second half of 1904 that features several readers' X-ray machines that use Wimshurst machines. The ME did a booklet on how to make one yourself. It also interviews the 18 year old author of a book on Radium and other radioactive elements, in which he describes how his experiments caused mutations in tadpoles. I do wonder if his house in South London managed to survive the Blitz, and if so, what its background radiation level might still be! There are also items on the need for experimenters to obtain wireless licences that were being introduced for the first time that year.
