The Natural History of Selborne

Strawberries from the woods are over; the crop has been prodigious.  The decanter, into which wine from the cool cellar was poured, became clouded over with a thick condensation standing in drops.  This appearance, which is never to be seen but in warm weather, is a curious phaenomenon, & exhibits matter for speculation to the modern philosopher.  A friend of mine enquires whether the “rorantia pocula” of Tully in his “de senectute” had any reference to such appearances.  But there is great reason to suppose that the ancients were not accurate philosophers enough to pay much regard to such occurrences.  They knew little of pneumatics, or the laws whereby air is condensed, & rarifyed; & much less that water is dissolved in air, & reducible therefrom by cold.  If they saw such dews on their statues, or metal utensiles, they looked on them as ominous, & were awed with a superstitious horror.  Thus Virgil makes his weeping statues, & sweating brazen vessles prognostic of the violent death of Julius Caesar:.. “maestrum illacrymat templis ebur, aeraq sudant.” Georgic 1st
