oned from fome Obfervations 5 I have met within your fa'd 
7'ranfa51^ion% , referring to my fubje£t. 
hndFir[t, in N^. 51. p. 1039 /. 40. in mentioning the 
Principles ot Scarkou^h-tvater , there was pretermitted Vitnvl ^ 
which I foppofe was not defignedly done, "i his I was to premiiep 
becaufefome things that follow do refer to that Mineral. 
Next^ I cannot but take notice of D. Feofs ingenious Notes 
and Letter in your Nwmk 52. p. 1050 : which he gronnds 
upon your enlarged Account of my Book, about the Volatil 
parts of Mineral waters , together with his ^erics^ To all 
which thoiigh I might have returned a fi3eedy Anfwer from old 
ObferVatidnl , yet I was willing to ftay , till my occafions could 
permit me toilep over to to renew my Experiments-, 
wherein as I refolved £0 be more Critical, fo I hopemy return 
will be more fatisfadory to all3 that are concerned. 
AsTor Tachenim^ to whom he refers^ I cannot get him in 
London^ therefore can fay nothing to his Principles. Ic is 
certain, thatthefe foits of Mineral waters -are miOre pleafanr 
to the palat , and alfo more elFeauil ^ if they be drunk at the 
Fountains 5 then when carried at diftance/ Yet fomeof them 
will endure carriage much better than others. Such of them , 
as are impregnated with a bodj of Mwu\^^^s Scarhonghy Mai- 
tony and the Sulphur-well 21 Krutresbrdugh ^ 'will better indur.e. 
carriage than th^ Sweet- wcdl :ii Knares-hrongh^md the Smvemr 
in Germciy.:j S:ic, which have imbibed little or nothing but the 
Volatil Spirits or Vapors of fome Minerals, which quickly e- 
vaporate, if removed from their Springs, 
Now though ScarbrGtigh^vjdiizi will endure carriage as far as 
any I know, and yet retain its purging quality, even to many 
days or weeks, when it ft inks , becaufeof its large proportion 
of Mineral Silts > which are not loft by carriage, and wil; car- 
ry it through the Body • yet certain ic is 5 that it uiffers a gre^at 
alteration and decay, of verto^e'^ ; being conveyed atdiftaoce ^ 
which' probably mail: 'proceed ■from the lofs of fome volatil

which it fiiould fortify the Crafts of the Siomach and other 
Nervous parts, or . open Obftru^ions, or e:spti the^Stone,c^v
