SHOWERS OF BLOOD EXPLAINED. 351 



in the suburbs of Aix, and for many miles around 

 it, and particularly the walls of a churchyard were 

 spotted with the blood. This occurrence would, no 

 doubt, have been chronicled in history as a super- 

 natural prodigy, had not Aix possessed at this time, 

 in M. Peiresc, a philosopher, who, in the eager pur- 

 suit of all kinds of knowledge, had not neglected the 

 study of insects. It is accordingly related, in the 

 curious life of Peiresc by Gassendi, that he had, 

 about the time of the rumoured shower of blood,

 this was further corroborated by his finding none of 

 the red drops in the heart of the city, where the butter- 

 flies were rarely seen. He also remarked, that the 

 drops were never on tiles, and seldom on the upper 

 part of a stone, as they must have been had they 

 fallen from the heavens, but usually appeared in

 up a supposed red earth into the air that had tinged 

 the rain ; no less wide of the truth than the popular 

 superstition which ascribed it to magic, or to the 

 devil himself* Those who are curious to verify the
