Solutions of Dextran Ph, Plasmoid, Periston and isotonic saline were compared with serum albumin and whole blood to determine the efficacy of the former as blood substitutes. Rats, guinea pigs and dogs were used as experimental animals. Dextran Ph, Plasmoid and Periston were found to be less satisfactory than whole blood, since 50 to 80 per cent of the rats and guinea pigs survived following their use compared with 100 per cent survival when whole blood was given. There was, however, 100 per cent mortality of the animals when a blood substitute was not given.
