were made upon the whole Plant,or fome Portiow of it wherein feveral 
Parts are mixed together: And others, upon fome one Part of a Plant 
diftinét from the feft. All of them anfwering to fuch Queries, as may 
feem proper to be propofed. 
Query 1. Asfirft, Whether Trees or Herbs and Bufhes, quantity for 
quantity & ceteris paribus,yeild the moft Lixivial Salt ¢ 
For thisf took A(b-Barque and Rofemary of each tbj. The latter 
yielded 5 Scruples ; the former but 32 Grains ; which is three times lef, 
I took alfo the fame quantity of the Barque of Black-Thorn, and of A- 
grimony, The latter yielded 5 Scruples and 6 Grains 5 the former, not 
above 1 Seruple and 5 Grains 5 which is four times lefs. 
Although the Barque of a Tree be compounded of Pithy and Lignous 
Parts 3 yet to anfwer the Query exactly, the Wood of thefé Trees thould 
be taken with the Barque, that there may be fome portion of every 
Part of the Ivee, as well as of the Herb. 
But thus far the Experiment is conclufive, That the fame quantity of 
Lixivial Salt, doth not always follow the fame Generical Tafz. For the 
Barque of Afh and Rofemary, are both equally Bitter; and the Bargue 
of Black-Thornz and Agrimony are both Affringent and Bitter. 
Quer. 2. Whether any Plant growing in a Garden or the Field, doth 
not yield a leffer quantity of Lixivial Salt, than another of the fame kindred 
growing on the Sea-Coaft , and with what difference > 
For this, I took Garden and Sea-Scurvygrafs, of each tbj. The for- 
mer yields 2 Drachms and 1 Scruple; the latter, being well wathed, 
9 Drachms, which ismore than 4 times as much. The like may be 
tryed upon others. 
Quer. 3. Whether the fame specifich Plant affords more Lixivial 
Salt, being only dryed, and then calcin'd 5 or after it hath first been diftil- 
led, it is then dryed and calein'd2 ; 
For this, wastaken ttj of Mizt only dryed and then calcin'd; and 
another firft diftilled. The former yielded 3 an Ounce and} a 
Drachm of Salt ; the latter, 5 Drachms and a Scruple 5 which is almoft 
- 52 more. This alfo fhould be tryed on other Plants. 
Quer. 4. How far the proportion follows the different Tafts of Plants? 
The firft Experiment, relates to the fame Tasf in feveral Plants ; this, 
to feveral Tafts, _ And fo, 
Of Majorane, which is Arowatick, tbj affords but one Scruple of Lixi- 
vial Salts, which is but the 384th part of the whole pound. 
Of Ozk-Barque which is Affringent, {bj yields } a Drachm of Salt ; 
or the 256th part of the whole, 
Of Liquirifh, which is fweet, 1b) yields about the fame quantity. 
But Avife Seeds tbj yields 2 Scruples or a 1924 part. 
OF Sorrel, which is ower, {bj yields one Drachm, or the 128 part. 
OF Garden Scureygrafs, which is Hot, tbj yields 2 Drachms and 4 a 
Scruple 5 or the 59th part. 
Of Mint, which. is Hot and Bitter, tbj yields 5 Drachms and a Scru- 
ple, or the 24 part. 
OF Sea Scuroygrafs, which is Salt, 1b) yields 9 Drachms and a Scru- 
ple or 28 Scruples 3 which is near +,th part of the whole. A greater 
proportion of Su/t, than in any other P/ext upon which I have hitherto 
made Tryal : Or even in Tartar it felf Yet is it not a Marine, but 
true Lixivial Salt : asis evident, both from its Ta/fe; and in that it 
maketh
