Interactive plates

Memoirs and Proceedings of the Chemical Society

Interactive plates from volumes II and III

These plates are present in the original volumes as discs freely rotatable by the (careful) user. They have been rendered here as Macromedia Flash animations to preserve their functionality and interactivity. You can move the discs by grabbing the pointers and handles with the mouse (click and hold) and moving them round.
