And that there is fome air both in anelaftick and unelaftick ftate, mixd with theearth, (which may well enter the roots withthe nourifhment) I found by putting intothe inverted glafs z z a a full of water(Fig. 35.).fome earth dug up in an alley inthe garden, which after it had flood foak-iiig for feveral days, yielded a little elaftickair, thos the earth was not half in Experiment 6%. we find that a cu-bick inch of earth yielded 43 cubick in-ches of air by diftillation, a good part ofwhich was roufed by the action of the firefrom a fixd to an elaftick ftate.

VI. A fpecimen ofan attempt to analyze the Airby a great variety of chymio-fiatkal Ex-periments, which fhew in how great a pro-portion Air is wrought into the comfoji-tion of animal^ vegetable, and mineralSubftances, and withal how readily it re-fumes its former elaftickftate, when in thedijfolution of thofe Subftances it is dijm-gaged from them.
