28 A NATURALIST IN THE PACIFIC chap. 



A. Analysis by Dr. C. T.Jackson of Boston, U.S., of the water 



obtained in 1840 by the Wilkes Exploring Expedition?- 



Specific Gravity I '0097. Temperature 57° F. 



The evaporation of a quantity equal to 1000 grains of distilled water gave 

 7'2 grains of salt, thus composed : — 



Chlorine 3-577 



Sodium I '665 or Soda 2'238. 



Magnesia 0^440 



Lime o'366 



Silica and iron with a trace of phosphate 



of lime o'20o 



Carbonic acid o'493 



6741 

 Organic matter and loss o'459 



7 "200 



B. Analysis by Dr. Oscar Pieper of Hamburg of the water 



obtained by Mr. Kleinschmidt in May, 1 876.^ 



The report stated that the water was clear, neutral in reaction 

 and salt-bitter in taste, brown flakes of hydrated iron oxide occur- 

 ring in it after long standing. The dissolved salts amounted to 

 " 8 -48 g. per litre," and the remark is made that " the concentration 

 is therefore not so great as in sea-water." The solid constituents 

 consisted in by far the greatest part of Natrium and Calcium 

 chlorides. A quantitative determination, which on account of the 

 small quantity of the water was confined to " eine Chlor und Kalk- 

 bestimmung," gave this result : — 



Chlor (Chlorine) 479 g. per litre. 



Kalk (Lime) 2-31 „ „ 



Reckoned as Chlornatrium (Kocksalz) and Chlorcalcium, these 

 results were obtained : — 



Chlorcalcium (Calcium chloride) 4*55 g. per litre. 



Chlornatrium (Sodium chloride) 3-09 „ „ 



Amongst other constituents found in small quantities were 

 Sulphuric acid. Silicic acid (Kieselsaure), Potash, and Iron oxide. 

 Iodine, Bromine, Nitrates, and Borates were completely wanting. 

 " If this water," says Dr. Pieper, " has healing properties, it does not 

 owe them to its chemical composition."
