eAn Idea of a 
Mellow Earth, with Sand, or with Clay; or Sand with Clay; or alto- 
gether 5 and in what Proportions. The Principles whereinto any one 
of thefe Ingredients, {eparated from the reft, and put to the Teft of 
Diftillation, ‘Oftion, Calcination, or other, either alone, or by mix- 
ture with other Bodies, may be Refolved. And by their Qualities, as 
Colour, Smell, Tafte, &c. both Ingredients and Principles to be exami- 
ned. To make tryal of the growth of Plants, in all kinds of fimple 
Soils 5 either Earthy or Mineral, as Clay, Marl, Oker, Fullers Earth, 
Bole Armeniac, Vitriol, Allum, oc. or Vegetable, as Rotten Wood, 


~ Brans, Starch, or Flower, @c. or Azimal, as Dungs, pounded Fleth, 
dried and powdered Blood, and the like 5 that it may appear, how far 
any of thefe may contribute to the growth of a Plavt 3 or to one,above 
another. 
59: §. Next of the water, and ofall Liquid Receptacles. ‘Where 
the feveral kinds of Water, from Wells, Springs, Rain, and Rivers are, 
by their Qualities and Faculties, to be examined; as thefe, and by 
thefe, their Principles; either in their Natural State, or upon Digefti- 
on, or otherwife, may be obfervable: fince Common Water it felf, is 
undoubtedly compounded of feveral Principles; the fimplicity there- 
of, not being argued, from its Clearnefs and Tranfparency; for a Solu- 
tion of Alum, though it containeth a confiderable quantity of Earth, 
is yet very Clear: nor from its feeming to have neither Svel/ nor Tafte 5 
for Water-driekers will tell you of the varieties of both in different 
Waters. Befides, if thefe Qualities {hould be accounted rather Phan+ 
fic, than Senfe 5 the difference of Waters is yet more manifeft, from 
their different Effects, obferved by “ Cooks, Lanndreffés, Brewers, and. 
others, that have occafion to ufe them: for not to mix with Sope,with- 
out curdling 5 not to boil Meat tender, or without colouring it reds 
and the like, are the vices of fome Waters, not of others, which yet 
would feem, in Colour, Tafte,and Smell, to be the fame. Tryal fhould 
alfo be made of the growth of Plants in all kinds of Liquid Recepta- 
cles, as Common Water, snow Water, Sea Water, Urine, Milk, Whey, 
Wine, Oyl, Ink, Gc. Or any of thefe, with a folution of Suit, Nitre, 
Sal prunelle, Sope, or otherbody. And hereby to obferve what fol- 
lows, either in the Liquor, or in the Plant it felf: as if any fixed Body , 
being weighed before its diffolution in Water 5 and ifthe Plant,fet herein, 
groweth 5 the /Vater,being then evaporated ; whether the quantity ofthat 
diffolved body,continue the fame,or is leffened.So, whether any Vegetable 
will become Opiate,by growing a confiderable time ina plain Solution or 
Water-tinéture of Opzum 3 and the like. Which Experiments,what event 
foever they have, yet at leaft, for our further inftruGtion in the Nature 
of Vegetation, may be of wl. 
60. §. Next of Aer, where it will be requifite to inquire,what fore 
of Bodies may be herein contained : Itbeing probable, from the variety 
of Meteors formed herein; and of Vapours and Exhalations continually 
advanced hereinto; that fome or other ofthem, may bear an Analogy, 
to all Volatile Bodys, whether Avimal,Vegetable, or Mineral. The flou- 
rifhings alfo of Frozen Dew; and the Green. Colour, which the Aer 
gives the Ground or Water, when, for fome time expofed to it; and 
other effects 5 {eem to argue, that it is Impregnated with Vegetable Prin- 
ciples. ‘Yo confideralfo the peculiar Nature of that Body, which is ftri@- 
ly called, der, And of that true Aerial Salt,which to me, feemeth pro- 
bable,
