The starch of steamed potatoes is not destroyed to any great extent, but a little of it is converted into amylodextrine, i. e., yields a red reaction with iodine. There was no growth, or very slight, in Cohn's solution; very little growth appeared on silicate jelly (with Fermi's solution) at the end of 6 days. The. : 1 - ss v>j.
