The following pages are from a vintage educational booklet covering nutrition and "meat cookery," i.e. roasting, broiling and panbroiling, focused on the experiments in cooking, focused on the advantages of low heat. I'm including additional information on this old publication (below) because it seems to be rather rare and the film it supports / accompanies isn't documented well either.
