minutes later, at two inches deep ; an hour and a half later, 
at four inches deep ; and this cold had not reached six inches 
deep in five hours, showing how slowly cold descends into the 
ground. Before the eclipse was total Arion ater and Helix 
pisana were moving about as if it were evening ; the latter 
was exceedingly common.”
