Hoc autem ita esse a serpentibus licet aspicere, quae, per calorem cum exhaustam habent umoris refrigerationem, tunc acerrime moventur, per brumalia autem et hiberna tempora ab mutatione caeli refrigerata, inmota sunt stupore.
We can observe this in the case of snakes: they move quickest when the heat has drawn away the damp with its chilling effect; but in the rainy and wintry seasons they are chilled by the change of climate, and are sluggish and motionless.
