Hand as long as you pleafe, you iliall find no fatty 
Subftance fwimming upon them, as upon the Spaw Wa- 
ters. The volatile Sulphur evaporates fo ftrongly, that 
it carries up with it a C^uanlity of as one may 
fee after the Solution of the Vapours, congealed and 
frozen in Winter time, when it remains incorporated 
upon the Walls, in the Places where the Icicles were. 
Thefe Waters are in Weight equal to thofe of the Spaw \ 
coming frefli out of the Source, they appear whitilh, or 
bluiih, but having flood a-while and grown cold, 
greenifli. They are very pure, and leave no kind of 
Mud, or Lutum thermale^ behind them ; in cooling they 
yield a fmall Scum or Cream of Nitre. Far from their 
Source, being wrought upon by the Air, they let fall a 
little whitifli Sediment as thofe of Borcet do a blackifli 
one. They preferve the Colour of Rofes put into them, 
and caufe them not to wither, as doth common Water. 
The Vapours afcending from them make Silver Plate 
black, as thofe of Borcet make it white. The other 
Source of St. ^iritX^ Bath differs from thefe in no 
other Refpeft, fave that the Water thereof is cooler. 
It is referved in three Bafons. In this Well you find 
neither Sulphur nor Salt-petre flicking to the Sides, 
probably becaufe it is open or uncovered. 
II. The fecond, or fulphureo-nitrous Sort of Compus., 
&c. though they fpring up in feveral Places, and have 
different Wells, yet is the Nature of them all, their 
Compofition, and mineral Ingredients the fame. The 
Toor-MerX^ Bath hath one great Bafon or Receptacle, 
the Rofe Bath four, whereof two only are ufed, and St. 
Cornelius'^ Bath of this Mine two. Thefe Waters are 
fit for ufe at all Seafons, being of a temperate Hear, 
more efficacious, and of greater Force in their Opera- 
tions, than the firfl Sort •, they weigh two per Cent. 
more than they, and are of a flronger Scent. In thefe 
is never found any Sulphur condenfed, no not in their 
Wells, though they be covered : But when they are 
emptied, and new Water let in ( as in the Rofe Bath) 
the Water running down along the Walls and Seats, 
into the Bottoms of the Bafons or Confervatories, the 
external Air prevailing upon it, fo fpread, and in fuch 
little Quantity arrefls, fixes and condenfes its Sulphur all 
along the faid Walls and Seats, refreffiing the Eyes of 
the Speftators with its Beauty and Luflre. But the 
Water rifing in the beforementioned Bafons, and co- 
vering the Seats and Walls, the Sulphur again unites 
and incorporates with its Diffoivent, and difappears and 
hides itfelf therein. The Water of thefe Sources con- 
tains great Quantity of Sulphur, vere fine and fweet, 
kfs nitrous Salt, a little Vitriol, and lefs Allum, more 
of the other Minerals and Metals, than of the firfl 
Sort, or thofe of Borcet. So that they are more com- 
pounded, oleous and bituminous, than any of the other 
Sources •, and though they come out of the Earth ve- 
ry temperate, as to aftual Heat, yet can fick Per- 
fons hardly endure them for any long Time, for the 
moil part fcarce half an Hour. 
HI. The third Sort, which I call Sulphur eo~nitro -vi- 
triolic, and is alfo of St. Cornelius, differs from the Pre- 
cedent, in that the Tafle is a little more acid, the Smell 
fweeter, and liker that of Spirit of Vitriol, and the 
Touch lefs oily. It is of lefs Efficacy in Ufe than the 
fecond Sort, and of more than the firfl. Of this Source 
there are three Bafons, which, with the two others of 
St. Cornelius beforementioned, make five in this Houfe. 
Thefe Waters agree much in their Compofi- 
tion with the Precedent. They are very pure and 
clear, efpecially in their Wells ; and though they feem 
troubled in their Bafons, yet taken in a Glafs, they ap- 
pear clear. 
IV. The fourth, or Salfo-alumino-nitrous kind, are 
thofe of the Neighbourhood, or Borcet. Thefe come 
out of the Earth extream hot, and in great Abundance, 
are all of the fame medicinal Quality, have feveral 
Weils, and are referved in ten or twelve Houfes, each 
■whereof hath two Bafons, or Receptacles 5 befides 
which, there is a common Bath expofed to the Air, 
for the Ufe of poor People. Thefe Waters call off 
a copious Excrement or Tartar, which yet is not Stone, 
but only a Sand mingled with, and united to the ni- 
VoL. II. Numb, iij, 
the Beating of the cold Air on its Superficies, to which 
alfo concurs the Cold of the Walls expofed td the fame 
Air. Thefe Excrefcences are found in the fubterranean 
ConduitSjj not only of thefe, but the other Baths in the 
City j being held to the Fire, they foon become friable^ 
and are nothing but a pute round Sand like the common. 
The higher Houfes and Bafons have the more of this 
Tartar, yet is it fo little, that it is not to be feen or 
perceived in the Water. Thefe Waters are of a dif- 
ferent Species, Virtue, and Operation, from thofe of the 
City, are very eafy to fuffer, and ferve often for Di- 
vertifement and Recreation to Perfons that are in 
Health. The Contents of them are a great Quantity 
of Sea-Salt and Allum, lefs nitrous Salt, very little Sul- 
phur, and not much of metalhck Subftances. 
Concerning the Virtues and Effeds of thefe Waters 
inwardly taken, he difeourfes to this Purpofe : 
Thefe Waters taken inwardly are very available in 
the Phthifick, Ajihma, or Difficulty of Breathing, oc- 
cafion’d by tough Phlegm lodging in th^ Branches of 
the Wind-pipe ; againft the Weaknefs of the Stomach, 
Indigeflion, Crudities, Flatulencies, Vomitings, Hic- 
coughs, and inveterate Cholicks. They diflipate and 
dry up all Manner of Catarrhs and ferous Defluxions ; 
and are very proper to be drunk by thofe that are trou- 
bled with the Palfy, before the Ufe of the Baths, 
They quicken the Appetite, cleanfe the Blood, and 
open the Obflrudions of the Mefentery. They are of 
excellent Ufe againfl hypochondriacal Maladies, efpe- 
cially in fuch as have weak and cold Stomachs. They 
mollify the Hardnefs of the Liver, Spleen and Mefen- 
tery. They diffolve and bring away the Gravel of the 
Reins, and Icffer Stones : And here he produces many 
Examples of fuch as voided Stones upon the Drinking 
thefe Waters, and among the reft, of fome that had 
drank the Spaw Waters, and came from thence with- 
out receiving any Benefit. They cleanfe the Ulcers of 
the Bladder, diffolving not only the grofs, phlegmatick 
and vifeous Humours which coagulate the Stone, but 
even the Stone itfelf, whilft it is yet tender. They 
have fometimes cured intermittent Fevers of long Con- 
tinuance, and fcrophulous Tumours. They dry up and 
heal the Itch, Leprofy, and other Affections of the 
Skin. They flop the immoderate Flowdng of the 
Menfes in Women, and cure the Jaundice, the Pale- 
nefs and Difcolouring of the Skin in Virgins : And fi- 
nally they give Eafe and Relief in the Gout. Of all 
thefe Faculties, he brings Inftances and Examples of 
Perfons that have been cured. Particularly, that thefe 
Waters drunk may have a Power of diffolving the 
Stone, he proves by this Experiment : Taking a Stone 
voided by a Man about two Years before, and infufing 
it in Water hot from the Fountain, for the Space of 
three Days, we found it (faith he) mollified and reduced 
into a foft Phlegm. Which Virtue of the Waters was 
further confirmed to us by a late Accident : For open- 
ing the Vault of a Well, there was found a certain Glue 
or Mucilage, which, it is to me probable, came from 
the Solution of the Mortar of Lime and Sand in long 
Time, by the volatile and diffoivent Spirits of the Wa- 
ters i efpecially there being found no other Cement be- 
tween the Stones, and in that this fame Glue or Muci- 
lage mingled itfelf intirely with the Waters of the 
Fountains, without any Appearance of Scum or Fat 
fwimming on the Top, as Gum of Cherry, or the 
like is wont to do in Water, and being caft into 
the Fire burnt not, but dried up. Thefe Experiments 
and Obfervations were made upon Occafion of a Bur- 
gomafter of Riga (who being afflidted with the Stone, 
drank thefe Waters) his paffing his Urine through a 
Linen Cloth, and finding therein a certain thick Phlegm 
left behind, which, being kept a while upon Paper, 
harden’d into a flony Subftance. 
15. From Aken we continued our Journey to Juliers, 
five Hours thence, a fmall but neat City, the Houfes 
low, but of Brick, the Streets are fomewhat narrow, 
yet it has a fair Market-place. Its Fortifications are 
confiderable, but the Citadel, in which is the Diical ' 
Palace, may compare for Beauty, Bignefs and Strength,
