i : r is too, while the duration and intensity of the wind - remain the 
‘ same. . At the head of the bay, the phenomenon will thus be exhib- 
ited, of the recession of water in the face of a strong current of wind. 
__ This occurrence has no doubt led to the opinion already referred 
_ to, and tlfe same appearances will be exhibited, though«in a less 
ing degree, upon the shores of all the lakes. A slight variation 
‘Ufthe force, or direction of the wind, will occasion a change in the 
elevation of the water, seeking at all-times to attain a level; and 
nations of ebbing and flowing will thus be exhibited, aided no 
loubt by the conformation of the coast, not easily reconcilable to the 
7 actual state of the wind. Very respectfully your obedient servant,

Arr. I—4 Notice of the Salt Springs of Moutiers, in the Taren- 
taise, (Alps) and of a peculiar method of evaporation; extracted 
rom the Travels of R. Baxewet, Esq.: Vol. I. p. 220: Lon- 
don. 
Introductory Remarks.—By permission of the author, we insert 
' following extract, presuming that the method of evaporation here | 
described may be advantageously adopted in this country, especially 
m the case of springs whose impregnation is weak. We are aware 
that methods, depending on the same principle, have been adopted 
In this country, but we are not informed that any of them have been 
Permanently successful. nine 
Tur springs that supply the salt works at Moutiers, rise at the 
om of a nearly perpendicular rock of limestone, situated on the 
South side of a deep valley or gorge, through which the Doron runs, 
hefore it joins the Isere. ‘The distance from the springs to the salt 
Works is about.a mile ; the water runs in an open canal, made for 
4€ purpose, but is received in a reservoir in its passage, where it 
deposits part of its ocherous contents. Formerly the.canal was con- 
tinued to Conflans, a distance of sixteen miles, where part of the wa- 
ler was evaporated. 
the water-rises from the rock with considerable force, and emits 
; much gas, which is principally carbonic acid, with a mixture of sul-
