The Journal of experimental zoology . salts of potassium.

After Uio hours there was still no expansion in KCl, a slight expansion wasbeginning in the KBr; in KNO3 all but the most central melanophores showedan expansion and all were expanded in KI and KSCN. After three hours, there was still no expansion in KCl; all the others werefully expanded and degeneration was well advanced in KSCN. After four hours all five scales showed expanded melanophores; in KI andKSCN degeneration was well advanced. These figures show clearly the protective anion sequence: Cl>Br>N03>I>SCN. 5S0 PHYSIOLOGY OF CHROMATOPHORES OF FISHES R. A. SPAETH PLATE 1. 581 PLATE 2 PHYSIOLOGY OF CHROMATOPHORES OF FISHES R. A.
