 circumstantial case is described by Hemmer : 



On June 30, 1788, a soldier in the neighbourhood 

 of Mannheim, being overtaken by rain, placed himself 

 under a tree, beneath which a woman had previously 

 taken shelter. He looked upwards to see whether the

 appearances, immediately concluded that I had received 

 the battery discharge. The intellectual consciousness 

 of my position was restored with exceeding rapidity, 

 but not so the optical consciousness. To prevent the 

 audience from being alarmed, I observed that it had
