| Analysis of Sea Waiter. Qa] 
the specific gravity amounted to 1-0274. This ap to be 
the greatest weight. 
When weighed in fair weather in December, it was almost 
1:0271; after rain I found it to be 1:0267. These variations 
will of course depend entirely on the state of the weather. If the 
atmosphere be bright, and no heavy rain has lately fallen, the 
water will have, even close to the shore, the same specific weight 
as out at sea, but after rain it is obvious that the sea-water 
to the shore will be most diluted. It is therefore indispensable 
that the sea-water for examination should be taken at a distance 
of several miles, that its specific weight should be ascertained, 
and that the analysis should be performed from one and the 
same dip. 
i t I cannot conclude this paper without drawing the attention of 
medical men to the importance which the brine-springs on the 
Continent have lately acquired, as, for instance, the springs near | 
Kissingen, | the Adelheids-quelle, near Heilbroun, and above all, 
the springs of Kreugnach, which have been found highly bene- 
ficial in scrofulous diseases when internally administered, their 
action being dependent entirely c on the chlorides, iodides, and bro- 
. ' mides they contain. Sea-water would afford similar advantages 
. for bathing, and when evaporated to dryness, the residue might 
., be kept i in earthen vessels, and thus be conveyed to any distance ; 
ae and as its constituents are very soluble, sea-water in perfection 
: t be procured at any. place. The evaporation of sea-water
