This change continues to proceed af 



feberries, apples, oranges. 



the pears and apples, or oranges, are taken from 



florehoufes, but the fruit in this fituation continues to ripen by 

 getable procefs, as it can not be faid to be dead, becaufe it do(

But there are other means of increafing or haftening the fa

cal produaion or increafe of fugar in vegetable juices is worth being 

 further inquired into ; fince if fugar could be made from its elements 

 without the affiftance of vegetation, fuch abundant food might be 

 fupplied as might tenfold increafe the number of mankind ! 



It is a curious circumftance not yet fufficiently underflood, that not 

 only ftarch appears to be convertible into fugar by the vegetable pro- 

 cefs of digeftion, as in the germination of farinaceous feeds ; but that 

 fugar is capable of being converted into ftarch, as appears in the ri- 



pening procefs of forae pears, which firil contain a fweet -juice, a 

 afterwards become mealy.
