The people faid that it prognofti- in thefe new plants, after being fet at liberty from the ftrufture of the laft year's plants by putrefaction, or by fire. Mould, che- jnically examined, has the fame analogous parts. Acid and cau- |tic are plentifully contained in the common air, and may alfo eafily be reftored to the mould, and thus circulate through a new fyitem of plants. Water comes fikewife from raia and fnow, -out of our atmofphere ; alkaline and oily particles, or a kind of/oaj> s are t...he only things wanting, which, when added with the former to any fubtle earth, will make a good mould ; and thefe are pro-? cluced by putrefaction or fire, from vegetable and animal fub^ fiances, and are the great promoters of vegetation. BUT the great queltion is, from whence thefe various fub- $ances, neceiTary for vegetation, originally came ? To believe they are produced from pu trifled vegetables, is begging the quef- tion, and making a circulus vitiofus in the argument. There is therefore no evafion ; they were certainly produced by the great Creator of the univerfe, and endowed with fuch qualities as make them capable of producing in various mixtures new bodies ; and u-hen they are introduced by moiilure into the firft ftamina of a plant, or a feed, they expand thefe ftamina, and conilitute a new being, capable of affording food to the animal creation.
