. Effects of the rays of radium on plants . Fig. 45. Experiment 54. Increased Growth of Zca Mays, following a ten-day Retardation, after the Seeds (before planting) were soaked in freshly fallen Rain Water. Summary The experiments show that when corn grains were soaked for 24 hrs. in water exposed for hrs. to radium rays growth was accelerated. The water exposed to the stronger radium caused the greater acceleration. With seeds of Lupinus albus similarly treated, the effects were very slight, but the same in kind as with corn. Oats seemed to be slightly retarded at first, but four or five

The water exposed to the stronger radium caused the greater acceleration. With seeds of Lupinus albus similarly treated, the effects were very slight, but the same in kind as with corn. Oats seemed to be slightly retarded at first, but four or five days after the planting the oats soaked in the exposed water were much taller than the control plants, and tallest after soaking in the water exposed to the strongest radium. In a similar experiment, after 40 hrs. of soaking in water pre- viously exposed for 24 hrs., oats were accelerated from the begin-
