Te an Effervefcence with Spirit of Salt 5 which Sea-Sakt will 
not do. 
For the Experiment to be fully adequate to the Query 3 the 
fhouldbe made,either all on Trees, or aT on Herbs 3 all a rniee: 
on Stalks, &c. Yet thus much is evident, That sorrel yields Thrice as 
much as Majorane Sea-Scurvygraft, Eight and Twenty times as much: 
Mint, Five times asmuch as Sorrel 3 and Sixteentimes as much Majo= 
rane, &c. 
Quer. 5. How far the Proportion follows the Faculties of Plants 2 
And fo, it appears, that 
Majorane,a Cephalick,, hath a greater Proportion of Volatile Parts, than 
any of the Plants above mentioned, and fo far, is more agreeable to the 
Avimal Spirits, and Genus Nervofum. 
Agrimony, (a) an Aperient, yields above Five timesas much Lixivial (a) Quer. 
Salt, as Majorane. “Yet much lefs than many other opening Plants eye 
which are ftronger: 
Mugwort (t6j) yields two Drachms and two Scruples 5 or above half 
as much more as Agrimony. So that this Plant, though it hath no con- 
fiderable Taffe, and in that refpe& promifeth but little; yet yielding a 
good quantity of Lixivéal Salt, feems no contemptible Medicine to fub- 
due thofe Acidities which either by caufing Ob/frudions, or immoderate 
Fermentations, frequently diforder the Female Sex. 
Mint, yieldeth fill a greater quantity ; and is therefore, partly for 
the fame caufe fo excellent a Stomachick: And Rofémary,(b)which is ap- (b) Quer.t 
propriated both to the Head and stomach, yieldeth a midle quantity ai 
of salt; more than the chief Cephalicks, and lefs than the chief Stoma- 
chicks. 
Common Mallow ( tb} _) yields 5 Drachms and 2 Scruples. 7. e. the 234 
part of the whole. So that this Plant, though of a very mild Tafée, 
yet yieldsmore Sa/t than Adint it {elf a Bitter Plant. Whereby it no 
’ longer feems ftrange, that a Plant of fo foft-a Tafe, thould be very 
Dinretich, and fo evidently affe& the Reins. 
Rhubarb (2 Ounces) yieldeth fcarce any fixed Salt, fo far as can be 
judged by the Taffe of the Afbes, not more than a Grain or two. So 
that its Satis, in a manner, wholly volatile; and thereby apter to 
operate upon the Bilious parts of the Blood 3 which contein a far greater 
proportion of Volatile Salt, than do the Serous. 
OF the Caput Mortunwe or meer Earth, it is obfervable, that it 
was near # an Ounce or 3" part of the whole; Which is almoft Six 
times as much as the Caput Mortunm of Common Dock: and much more 
than that of any other Root Ihave yet calcin’d, Whereby it feemeth 
probable that Rhubarb loofeth much of its Volatile Part, and therefore 
of its Virtue, before it comes to our Shops. 
Sena (t6j) yields 4 Scuples and 4 of Sats or the 85* part. 
Falap (46) ) yields but one Drachm and 15 Grains, or 1024 part. 
Colocynthis ( tbj of the Pulp) yields an Ounce and half of Caput 
Mortuum, whichis almoft all Salt. Yet allow ‘half an Ounce of the Salt, 
and Earth to be wafted in filtring &c. theremaining Ounce is no lefs 
than 4,th part of the whole. Which is more than in any of the 
above named Plants, except the Sea-Scuruygra/s.
