KINDLE SEPARATION OF SALT EROM SALINE WATER noted in a few days that a thin fihn of salt has formed a narrow linear band around the inside of the glass and extended above the original sur- face of the water. This film widens through evaporation of the water around the sides of the glass, depositing a la3'er of salt on the glass just above the npper margin of this film. The film of salt continues to ad- vance slowly upward by capillary attraction and subsequent evaporation of saline water until the top of the glass is reached.

The film of salt continues to ad- vance slowly upward by capillary attraction and subsequent evaporation of saline water until the top of the glass is reached. It then in the same manner grows downward and eventually covers entirely the outside of the vessel. If the supply of saline water is renewed from time to time, the. Figure 1.—Salt Efflorescence The efflorescence has completely covered five vessels through the creep of the salt water over the sides of the innermost vessel water will be found to flow out of the glass quite rapidly after the salt incrustation is well developed and down over the outside in a continuous trickling sheet. The glass if set inside a series of larger vessels will in this way cascade its saline contents into each one in turn through the medium of the salt film. Constant thickening of the salt layer on each of the vessels is a concomitant feature of this barrier-climbing process. The salt incrustations on the five vessels shown in figure 1 were produced by placing salt water only in the inner vessel, from which it slowly cas- caded into the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Geological Society of America.
