As will be seen by a comparison inter se of the analyses made in 

 1876 and 1905 of the waters of Owen's Lake, California, a lake of 

 triple alkaline waters, and those of the Great Salt Lake. L'tah, made 

 in 1877, 1889 and 1892. a difference of salinity, amounting in the 

 case of Owen's Lake to 153.2 permille, and in that of Great Salt 

 Lake to 116.7 permille, obtained between the extreme dates. This 

 shows the variation in concentration of the smaller salt lakes. In 

 both cases it is seen that the concentration has been a progressive 

 one in time. For Great Salt Lake, successive analyses show the 

 following concentration, which, with the exception of the first, 

 shows a regular progression.
