N. 3. Whether any Vegetables may be fet fo an tagrm 

 in tioe Air* 



There is a queftion now-adays frequently projofed, 

 Whether there be more Soils then the ordinary 

 Turf or furface of the Earth, tempered with fome 

 water, foyl being meant for the ground, in which 

 things may be fet to grow. I need not fpeak much 

 upon it, as to Water, which by Experiments related 

 in the Chapter concerning Propagation by cuttings, 

 appears to have a property to elicite Roots, and make 

 - them where they were nor, and nourifh the Plants 

 by them after they were made ; to which, I mult 

 adde this circumstance, not before mentioned, that 

 Periwinckle, and divers others, continued their 

 growth by this nourishment alone, from year to year, 

 not dying in the Winter.- How long they might have 

 . continued, I can't afiert, for being abfent this Win- 

 'tcr, and no fires being kept near, the water in the 

 . Glaffes, was fo raryfied by the Froft, that the fides 

 could nor contain it, but were forced afunder there- 

 by, and fo the Plants peri/Hed ; whereas others ife, 

 they being fet in a 1 00m over my Laboratory, I que- 

 ftion nor, had many of them continued till now. 



Some put for.vard, that the Air might have the 

 faculty of nouri fning Vegetables 'afcribed to 

 it: And no wonder, when. Faracelfw makes it a
