THE GEOLOGIST. 
the theory which supposes the saline waters of this district to 
be derived from the saliferous deposits^ notwithstanding the 
thickness of the intervening beds, is not to say the least altogether 
of a hypothetical character. 
In a notice of the descriptive character of the present it will 
be necessary to state the different kinds of saline waters w^ith 
which our health-restoring springs are so bountifully supplied ; 
they may be divided into 1st, the Purgative, 2nd. the Tonic 
and Srd, the Alterative; the purgative consist principally of 
pugative salts, as chlorides and sulphates of the kaligenous 
metals, in various proportions, the Tonic waters have these salts 
in smaller quantities, but in addition they contain some salt of 
iron, mostly the sulphate, which gives them their tonic effects. 
The alterative consist of two kinds, the sulphur springs, vvhich 
derive their sulphur from the decomposition of iron pyrites which 
often occur in beds in the lias, these waters are particularly re- 
commended in cutaneous diseases, whilst the 2nd. kind of alter- 
ative, the ioduretted and bromine waters, act slowly upon the 
absorbents. Of course these different kinds of waters are not 
always exactly alike and this will account for the different result 
of each new analysis of them. —

" On newly discovered Ichthyolites in the new red-sandstone of 
New Jersey/' from W. C. Redfield, Esq. 
Mr. Redfield has found two distinct fish-Deds in the new red 
sandstone of New Jersey both containing ichthyolites of the genus 
Palaoniscus. In the sandstone between the fish-beds he discovered 
an Ornithoidicnite, and observed numerous slabs exhibiting im-
