When I was 10 or 11 my brothers and I found in the cellar under our new house a trove of Astounding, Amazing, Fantasic etc pulp fiction magazines. They dated from ~ 1930 to 1940 and were in good condition as the cellar was very dry. I read them all from cover to cover. A few stories stick with me, some of which I've been able to re-find via sites like the Internet Speculative Fiction Database. But one in particular has eluded all searches.
AFAICR the title was something like the The Crystal of Beryl, or The Beryllium Crystal. The story's title page pictured a crystal lattice. Somehow the protagonist has got inside it and is trapped there. The crystal has strange properties that lets him travel in time and space. This picture reminded me of it. Do I jog anyone's memory? Mine hasn't proved very useful! Suggestions also welcome.
