More on Wood's slides

I wrote about Professor Wood's lantern slides last time, and I have now found more about them. The slides were marketed by Newton & Co, and I found their 1920 catalogue on line in the Internet Archive.

This is the relevant section (click to enlarge):


So we now know that there are 47 slides and, as you'd expect, not all of them are infrared as they illustrated his talk on both IR and UV photography. So far I haven't been able to track down a set. Does anyone know of one?

Newton's also marketed a set of slides where Wood illustrated sound waves in photographs. This is a link to the catalogue.
