1. The stability against heat of the catalase in five species of marine algae; Ulva pertusa, Enteromorpha Linza var. crispata, Scytosiphon Lomentaria, Polysiphonia senticulosa, and Porphyra pseudolinearis, was examined. 2. The activity of the catalase in each of these algae was reduced by half when heated at 55°C for five minutes, and was completely extinguished when heated for thirty minutes at 60°C and for fifteen minutes at 65°C.
