The heat, which is perceived in the hotbeds, which 



are ufed for the growth of cucumbers and melons, is produced by 

 this union of oxygen and carbon, or by the generation of forae other?

That this heat is owing to 



the atmofpheric air combining w 



fome inflammable bafe, and producing acidity of fome kind, appears 

 from the following experiment.
