[18] Drebbel's modern day Francis Bacon, like della Porta a believer in science interaction, may not have already been existing for the demonstration, but inside a ebook posted later the same 12 months, he explained it as "experiment of artificial freezing" and reported that "Nitre (or instead its spirit) is incredibly chilly, and hence nitre or salt when extra to snow or ice intensifies the chilly from the latter, the nitre by including to its cold, even so the salt by giving exercise towards the cold in the snow."[fifteen]
