found near Bagneres in Gafcony : With

feeur Second at de Montefquieu, of the Aca-

* 
Read Mar. 8.^ | H O U G H the Spring called LaFon- 
I 743'4- taine du Saint is at a good Diftance 
from the Town of Bagneres-, it is, neverthelefs, as 
much frequented as any in that Country ; and, be- 
tides its admirable Effeds in curing a great Number 
of Diftempers, it likewife offers, to the Eyes of the 
Lovers of Natural Hiftory, a very remarkable Singu- 
larity. 
In the firft Bath, through which the largeft of the 
Two Branches of the Spring flows, there are found, 
from time to time, fmall Stones, of the Colour of 
Iron ruft, and of a regular Figure; being either 
Parallelopipedes with oblique Angles, of which the 
Sides are unequal ; or fmall folid Bodies with Six 
Sides, only differing from Cubes or Dice in this, 
that the Surfaces are not perfectly perpendicular one 
to another, but a little inclined ; as alfo commonly 
longer than they are broad, and broader than they 
are high. 
The largeft which I have feen were but 1 1 Lines 
in Length, 9 - in Breadth, and 6 in Height: They 
are moftly a great deal (mailer. I have one which 
is very odd, being a Parcel of an hundred in one 
Lump.
