6 A CONTRIBUTION TO THE STUDY OF ICE-STRUCTURES 



The temperature of the brine when bottled at the lake was 22° F. (necessarily 

 the temperature of freezing equilibrium for that particular mixture), further reduction

of the temperature caused a separation of H 2 as ice, but there was always a liquid 

 remainder even at temperatures far below zero Fahrenheit. 



Two different samples of the liquid brine from the bottom of this lake have been 

 examined by Mr. F. B. Guthrie, F.C.S., analyst to the Department of Agriculture, 

 N.S.W., with the following result :
