Diagram of a piece of experimental equipment (a small chamber) with notes on dimensions and construction
Biographical / Historical
The diagram was found with a small note written in German with which it seemed to share a provenance. This is a note of greetings from a German colleague and is written from Bonn, with the date given as 18th January 1913. There is the signature of the sender (not deciphered) who has a surname beginning with 'K'.
The diagram is stuck to a small piece of card bordered in red, on which the notes are written in what appears to be Rivers's handwriting.
