Effects of salt ions on the membrane formation by mechanical stimulus were studied. The material used was Strongylocentrotus pulcherrimus. The eggs were put into the following solutions respectively. 1 M urea 10cc + 0.54 M NaCl 5cc 1 M urea 10cc + 0.54 M KCl 5cc 1 M urea 10cc + 0.36 M CaCl_2 0.25cc or 0.06cc 1 M urea 10cc + 0.36 M MgCl_2 0.25cc or 0.06cc 0.45 M NaCl After one minute, the solution, containing the eggs, was sucked into a pipette and then was emitted violently from it. If the solution without Ca or Mg was used, the membrane elavation took place. But when the solution contained Ca or Mg, no memberane formation occurred.
